1. What the site is

TimerPlan is a set of calculators and reference pages. Everything that calculates runs in your browser and is free to use, with no account.

1 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 1 hour already in the box.

What people set 1 hour for

a workout, a long meeting, a slow bake, parking, a practice session. An hour is the unit everything else is measured against: the billing block, the meeting, the parking bay, the practice session. It is also long enough that a timer stops being about the alarm and starts being about not checking.

1 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 1 minute already in the box.

What people set 1 minute for

a plank, brushing one quadrant of your teeth, a quick brainstorm, resting between sets. One minute is the interval that feels shortest and passes slowest. It is the standard rest in strength training, a quarter of a proper tooth-brushing, and the length most people badly misjudge when asked to guess without a clock.

10 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 10 hours already in the box.

What people set 10 hours for

a four-day-week shift, an overnight sourdough prove, a long-haul flight, a slow cook on low. Ten hours is the shift on a four-day week, and it is where daily overtime rules start to matter in the places that have them. It is also a full overnight prove for bread that is going into a morning oven.

10 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 10 minutes already in the box.

What people set 10 minutes for

a tidy-up sprint, a guided meditation, a rice absorption rest, a break between lessons, a hard-boiled egg with a margin. Ten minutes is the second most-set timer after five, and it is the standard unit of a break — long enough to leave the desk and short enough to come back. It is also the classic length for a tidy-up that would otherwise take an afternoon.

10 Second Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 10 seconds already in the box.

What people set 10 seconds for

a plank hold at the end of a set, rinsing after brushing, a countdown before a take, holding a stretch at its limit. Ten seconds is the shortest interval a timer is worth opening for, and it exists mostly as the last stretch of something longer — the count before a recording starts, or the hold at the end of an exercise where the seconds have started to matter.

12 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 12 hours already in the box.

What people set 12 hours for

a nursing shift, an overnight cold prove, a fasting window, half a day. Twelve hours is the shift that runs hospitals and the fasting window most intermittent-fasting schedules start from. It is exactly half a day, which makes it the longest duration where the arithmetic is still obvious.

12 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 12 minutes already in the box.

What people set 12 minutes for

the Cooper test, rice by absorption, a pizza in a hot oven, a fifth of an hour. Twelve minutes is the Cooper test — run as far as you can and the distance estimates aerobic fitness. It is also exactly a fifth of an hour, which makes it a tidy slot in a lesson plan.

15 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 15 minutes already in the box.

What people set 15 minutes for

a quarter-hour billing block, a power nap, a short study block, roasting vegetables, a stand-up meeting. Fifteen minutes is the quarter hour: the unit timesheets round to, the length of a stand-up meeting, and the nap that leaves you clear rather than groggy. Almost every scheduling system in the world is built on it.

15 Second Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 15 seconds already in the box.

What people set 15 seconds for

a mouthwash rinse, a short social video, resting between heavy repetitions, a sprint interval. Fifteen seconds is the standard length of a short advertisement and of a mouthwash rinse, which is not a coincidence — it is about the longest a person will hold still for something without checking how much is left.

2 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 2 hours already in the box.

What people set 2 hours for

a long film, a slow cook, a parking session, a long exam, a deep work morning. Two hours is where a timer changes purpose: it is no longer counting down to an action, it is marking the end of a session. Parking, exams and slow roasts all live here, and all of them go wrong in the same way — by being forgotten.

2 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 2 minutes already in the box.

What people set 2 minutes for

brushing your teeth, steeping green tea, a plank challenge, boiling an egg for the very soft yolk. Two minutes is the dentists’ number, and it is roughly double what people brush unprompted. It is also the point at which most kitchen tasks stop being instant and start being worth timing.

20 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 20 minutes already in the box.

What people set 20 minutes for

a nap, a study block, a dough rest, an ice pack, a focused email session. Twenty minutes is the longest nap that avoids deep sleep, the standard ice-pack interval, and about the length of attention people can hold on something they did not choose. Three of them make an hour, which is why so many schedules are cut this way.

20 Second Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 20 seconds already in the box.

What people set 20 seconds for

washing hands properly, a Tabata work interval, a held stretch, a plank for a beginner. Twenty seconds is the hand-washing interval public health bodies settled on, and it is also the work phase of the Tabata protocol. Both are cases where the exact number matters more than it looks: at fifteen seconds the soap has not lifted much, and at twenty-five the interval stops being repeatable.

25 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 25 minutes already in the box.

What people set 25 minutes for

one pomodoro, a focused work block, a slow oven bake, a language practice session. Twenty-five minutes is one pomodoro, and it is the most deliberately chosen duration on this list — long enough to get somewhere, short enough that starting feels cheap. Four of them plus breaks is a working morning.

3 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 3 hours already in the box.

What people set 3 hours for

a slow braise, a long exam, a half working day, a road trip leg. Three hours is the length of a proper braise and of a long exam, and it is about as far as a browser timer should be trusted without a backup — long enough for a laptop to sleep or an update to restart something.

3 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 3 minutes already in the box.

What people set 3 minutes for

a soft-boiled egg, steeping black tea, a boxing round, a song. Three minutes is a boxing round, a pop song and a soft-boiled egg — three completely unrelated traditions that landed on the same length because it is about as long as full attention lasts without a break.

30 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 30 minutes already in the box.

What people set 30 minutes for

a workout, a roast in the oven, a meeting, a study half-hour, a proving dough. Half an hour is the default unit of a calendar. It is the length of the meeting nobody questions, the slot that most exercise fits into, and the point where a timer stops being a nudge and becomes a plan.

30 Second Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 30 seconds already in the box.

What people set 30 seconds for

a plank, a stretch held properly, resting between sets, an elevator pitch, a French press bloom. Thirty seconds is the interval people set most often below a minute, and the reason is that it is the shortest stretch that feels deliberate. It is a full plank for a beginner, a proper stretch hold, and the rest between sets in a circuit.

35 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 35 minutes already in the box.

What people set 35 minutes for

a chicken breast in the oven, a longer study block, a commute, a full circuit workout. Thirty-five minutes is an awkward number that turns up constantly in cooking, where it is the difference between a roasted vegetable and a burnt one. It is also a good study block for anyone who finds twenty-five too short to settle.

4 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 4 hours already in the box.

What people set 4 hours for

a half shift, a long slow roast, a fasting window, a long drive. Four hours is half a working day and the length of a proper slow roast. It is also the interval at which most break rules bite: many jurisdictions require a rest after six hours, and four is where people start feeling it.

4 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 4 minutes already in the box.

What people set 4 minutes for

a full Tabata protocol, steeping strong black tea, a poached egg, a warm-up row. Four minutes is the length of the whole Tabata protocol — eight rounds of twenty seconds on and ten off — and it is the shortest interval session with real evidence behind it. It is also a stubbornly common length for a decent cup of tea.

40 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 40 minutes already in the box.

What people set 40 minutes for

a school lesson, a gym session, a sleep cycle’s first half, a long roast. Forty minutes is the length of a lesson in a large part of the world, and it is not arbitrary: it is roughly the point at which sustained attention drops off sharply in a room of people who did not choose to be there.

45 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 45 minutes already in the box.

What people set 45 minutes for

a school period, a football half, a therapy hour, a deep work block, a long roast. Forty-five minutes is the standard period: a lesson, a half of football, and the so-called hour of most professional appointments. Three quarters of an hour turns out to be the length of most things that need a whole person’s attention.

45 Second Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 45 seconds already in the box.

What people set 45 seconds for

a work interval in a circuit, a wall sit, steeping delicate green tea, a timed speaking turn. Forty-five seconds is the work phase of the most common gym circuit — forty-five on, fifteen off, which fits eight exercises into eight minutes. It is long enough for form to matter and short enough to finish.

5 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 5 hours already in the box.

What people set 5 hours for

a long flight, a slow smoke, a study day, a shift. Five hours is a transatlantic flight leg, a barbecue smoke, and about the longest single stretch anyone should plan to work on one thing. It is a duration for a device that will stay awake, not for a laptop lid.

5 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 5 minutes already in the box.

What people set 5 minutes for

a jammy egg, a short meditation, a plank challenge, steeping herbal tea, a break between tasks. Five minutes is the most-set timer there is. It is short enough to feel free and long enough to change something: a break, an egg, a tidy-up, the meditation people actually keep doing.

50 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 50 minutes already in the box.

What people set 50 minutes for

a therapy hour, a university lecture, a deep work block, a long bake. Fifty minutes is the professional hour — the appointment length that leaves ten minutes for notes, and the lecture slot that leaves ten for moving buildings. Anyone charging by the hour is usually working to it.

6 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 6 hours already in the box.

What people set 6 hours for

a shift, an overnight prove, a slow cooker on high, a long journey. Six hours is the point at which working-time rules start applying in much of the world, and it is also the setting on most slow cookers’ high mode. It is a duration you set and leave the room for.

6 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 6 minutes already in the box.

What people set 6 minutes for

a tenth of an hour on a timesheet, a walking test, steeping oolong, a fast pasta. Six minutes is exactly a tenth of an hour, which is why US payroll rounds to it: the decimal figure stays tidy. It is a rare case of a duration chosen for arithmetic rather than for the task.

7 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 7 hours already in the box.

What people set 7 hours for

a night’s sleep, a working day less lunch, a long prove, a slow cook on low. Seven hours is the sleep figure health bodies converged on as the sensible minimum for adults, and it is also the working day once lunch is out of it. Two very different reasons for the same number.

7 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 7 minutes already in the box.

What people set 7 minutes for

the seven-minute workout, a medium-boiled egg, a focused tidy-up, a phone call you want to keep short. Seven minutes exists as a duration almost entirely because of one workout: twelve exercises, thirty seconds each, ten seconds between them. It is the shortest session that covers the whole body and still counts as exercise.

8 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 8 hours already in the box.

What people set 8 hours for

a working day, a night’s sleep, a slow cooker on low, a full shift. Eight hours is the working day, and it was a demand long before it was a norm — the eight-hour movement of the nineteenth century wanted eight for work, eight for rest and eight for what we will. Two of the three stuck.

8 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 8 minutes already in the box.

What people set 8 minutes for

a hard-boiled egg, dried pasta, a rice rest, a circuit of eight exercises. Eight minutes is the kitchen’s number: hard-boiled eggs, most dried pasta, and one round of a forty-five-on fifteen-off circuit through eight exercises. It is also about how long a kettle-to-cup tea ritual takes end to end.

9 Hour Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 9 hours already in the box.

What people set 9 hours for

a working day with lunch, a long sleep, an overnight ferment, a shift with a handover. Nine hours is the working day once an unpaid lunch is added back in — nine on the clock for eight paid — which is the single most common shape of a full-time day and the reason timesheets need a break field.

9 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 9 minutes already in the box.

What people set 9 minutes for

the standard snooze, a firm hard-boiled egg, a short walk, a warm-up. Nine minutes is the snooze interval every alarm clock inherited from mechanical ones, where the gear train could not manage a clean ten. It survives on phones for no reason other than habit.

90 Minute Timer

Tue, 11 Aug 2026 00:00:00 +0000

Press start, or press it after changing the length — this page is the ordinary timer with 90 minutes already in the box.

What people set 90 minutes for

a sleep cycle, a film, a football match, a long study block, a slow roast. Ninety minutes is the length of a sleep cycle, a football match and most films — three things that found the same number independently. It is also the outer limit of a single work block for most people.

About

Tue, 11 Aug 2026 00:00:00 +0000

TimerPlan is a set of free browser tools for keeping time: countdowns that ring, a stopwatch, clocks for other places, calculators for the arithmetic of hours, and colour panels that turn a screen into a light. Everything runs inside the page, on any modern browser, with nothing to install.

Why it exists

Because a timer is a thing you set and stop watching, and most browser timers are built for the state where you are watching. We measured three ways of building a countdown in a frozen tab: the common ones lost 119 and 147 seconds out of 150, and the method used here lost none. The measurement, the script and the numbers are on the timer accuracy page.

Black Screen

Tue, 11 Aug 2026 00:00:00 +0000

What a black field shows that a bright one does not:

Visible on black	Usually caused by
Fine grey haze	Dust, or a cloth that has been used dry too long
Streaks	Cleaning fluid applied directly to the glass
Fingerprints	Touchscreens, and pointing at things
Bright patches at the edges	Backlight bleed on an LCD — a panel trait, not dirt
The room	Reflections; move the light or tilt the screen

Cleaning goes in that order: dry cloth for dust, barely damp cloth for the rest, and the black panel between each pass to see what is left.

BPM Counter

Tue, 11 Aug 2026 00:00:00 +0000

Typical tempo ranges, for when the number needs a sanity check:

Style	Usual BPM
Ballad, slow blues	60–80
Hip hop	80–100
Rock, pop	100–130
House, disco	118–128
Techno	125–150
Drum and bass	165–180

If your reading lands near the edge of one of these, check the half and double figures before believing it — most disagreements about tempo are really disagreements about where the beat is.

Once you have a number, the metronome will hold it, nudge it by one or five, and add subdivisions for practice. For timing the length of something rather than its tempo, the stopwatch takes laps, and the seconds to minutes converter turns a running time into whatever unit the rest of the job wants.

Browser Timer Accuracy

Tue, 11 Aug 2026 00:00:00 +0000

The measurement

Chrome 151, Windows, measured 11 August 2026. Every figure is what each method reported as elapsed, against the system clock outside the browser.

Scenario	Real elapsed	Absolute finish time	Tick counting	Frame counting
Tab in front, 30 s	30 005 ms	30 004 ms	30 000 ms	29 989 ms
Frozen 30 s of 60	60 002 ms	59 014 ms	30 000 ms	2 997 ms
Frozen 120 s of 150	150 002 ms	150 002 ms	31 000 ms	2 986 ms

Read as error, which is the way it matters:

Chess Clock

Tue, 11 Aug 2026 00:00:00 +0000

Common time controls and what they are for:

Control	Meaning	Usual setting
Bullet	1+0	One minute each, no increment
Blitz	3+2 or 5+3	The default for a casual game
Rapid	10+5 or 15+10	Club evenings, online rapid
Classical	90+30	Tournament play, with the increment from move one

Set the base time and the increment below the clocks, then press either side to begin — the other side’s clock starts, because white has just moved.

Classroom Timer

Tue, 11 Aug 2026 00:00:00 +0000

Lengths that come up in a lesson, and what they are usually for:

Length	Typical use
30 seconds	Think-pair-share, first turn
1 minute	Tidy-up, transition between activities
2–3 minutes	Pair discussion with a question on the board
5 minutes	Independent written task, starter or exit ticket
10–15 minutes	Group work with a product at the end
20 minutes	Reading, extended writing, carousel station

The timer accepts anything typed as 5m, 90s or 5:30, and the address bar keeps it — so a bookmark called “5 min task” opens this page already set, and adding &auto=1 starts it on opening, which saves a click in front of a class.

Count Up Timer

Tue, 11 Aug 2026 00:00:00 +0000

Set a target if you want one — 45m, 1h, 90m — or leave it empty and simply count.

Use	Target	Why
Instrument practice	30–45 min	Long enough to get past warming up
Language study	25 min	Pairs with a pomodoro cycle
Billable work	1 h	The unit most invoices are written in
Reading	1 h	Progress matters more than a deadline
A shift	8 h	Watch it fill; check the total against the timesheet

When the session ends, the hours calculator turns the elapsed time into hours in both forms — h:mm for the clock, decimal for the invoice — and the time card calculator does the same for a whole week.

Countdown Timer

Tue, 11 Aug 2026 00:00:00 +0000

Type the time the way you say it. All of these are understood:

What you type	What it means	Ends
`3pm`	Three in the afternoon	Today, or tomorrow if it has passed
`15:30`	Half past three, 24-hour	Today, or tomorrow if it has passed
`12:00 am`	Midnight — the start of the day	Tonight
`12:00 pm`	Noon	Today, or tomorrow if it has passed
`0645`	Quarter to seven in the morning	Tomorrow, if set in the afternoon

The two rows in the middle are the ones worth reading twice. Twelve o’clock is the only hour where AM and PM behave the opposite way to instinct: 12:00 AM starts the day and 12:00 PM is the middle of it. The military time converter has the same trap written out in full, which is one reason 24-hour notation exists.

Decimal Hours on a Timesheet

Tue, 11 Aug 2026 00:00:00 +0000

The table worth keeping

Minutes	Decimal	Minutes	Decimal	Minutes	Decimal
5	0.08	25	0.42	45	0.75
6	0.10	30	0.50	48	0.80
10	0.17	35	0.58	50	0.83
12	0.20	36	0.60	55	0.92
15	0.25	40	0.67	60	1.00
20	0.33	42	0.70

Two rows are worth noticing. Six minutes is exactly 0.1 hours, which is why US payroll so often rounds to six-minute blocks — the decimal stays clean. And 20 minutes is 0.33, not 0.20, which is the single most common wrong entry after the half hour.

Free and Pro

Tue, 11 Aug 2026 00:00:00 +0000

Everything that calculates here is free and always will be — no account, no sign-up, no limits on how often you use it. That is not a trial. Search engines send people here to get an answer, and an answer behind a wall is not an answer.

Pro is for what happens around the answer. It remembers your setups on every device you sign in on, turns any result into a page you can send someone, lets you put a tool on your own site, emails you when a date you care about is coming, and takes the ads off every site we run — with one account and one price.

Full Screen Clock

Tue, 11 Aug 2026 00:00:00 +0000

Reading distances, roughly, for the full-screen digits on a typical display:

Screen	Comfortable reading distance
Phone, held	1–2 m
Tablet, propped	3–4 m
24–27 inch monitor	6–8 m
Television or projector	The room

Those are the same numbers that decide whether a classroom timer works from the back row, which is why both pages fill the screen the same way.

For a clock that counts rather than tells the time, the online timer counts down and the stopwatch counts up. For other places, the world clock holds a list of cities and the time zone converter converts a single time. To leave a screen on without lighting the room, the black screen is quieter than any clock.

Green Screen

Tue, 11 Aug 2026 00:00:00 +0000

The two values, and when to use each:

Panel	Hex	Use it when
Chroma green	`#00B140`	The default — nothing green in shot
Chroma blue	`#0047BB`	Subject wears, holds or contains green

Both are on the swatch row along with white, black and the warm and cool whites, so a single tab covers lighting and backdrop.

If the panel is behind the subject, something else has to light them — the white screen on a second device is the usual answer, and warm or daylight white depending on the room. To check the panel for dirt or reflections before a take, the black screen shows what the green hides.

Hours Calculator

Tue, 11 Aug 2026 00:00:00 +0000

The conversion table worth keeping, since it is the same six numbers every time:

Minutes	Decimal hours	Minutes	Decimal hours
5	0.08	35	0.58
10	0.17	40	0.67
15	0.25	45	0.75
20	0.33	50	0.83
25	0.42	55	0.92
30	0.50	60	1.00

Six minutes is exactly a tenth of an hour, which is why US time cards so often round to six-minute blocks: the decimal figure stays tidy without anyone having to think about sixtieths.

Interval and HIIT Plan

Tue, 11 Aug 2026 00:00:00 +0000

Build a session out of work and rest intervals with a round count, and see the total length before you start rather than fifteen minutes into it.

Interval Timer

Tue, 11 Aug 2026 00:00:00 +0000

The settings that come up most, and what each one is:

Work	Rest	Rounds	Total	Known as
20s	10s	8	4:00	Tabata
30s	30s	10	10:00	Even intervals, conditioning
40s	20s	8	8:00	The standard class round
45s	15s	8	8:00	Circuit, eight stations
60s	60s	8	16:00	Rowing and running repeats
3m	1m	3	12:00	Boxing rounds

The last row is worth noting: boxing has used three minutes on and one off for over a century, and it is a 3:1 ratio — the same shape as a gym circuit, an order of magnitude longer.

Kitchen Timer

Tue, 11 Aug 2026 00:00:00 +0000

Common timings, if you want somewhere to start:

Item	Time	From
Soft-boiled egg	3 min	Water already boiling
Jammy egg	5 min	Water already boiling
Hard-boiled egg	8–9 min	Water already boiling
Dried pasta	8–12 min	Return to the boil
Rice, absorption	12 min + 10 min rest	Lid on, heat off for the rest
Steeping black tea	3–5 min	Water off the boil
Steeping green tea	2–3 min	Water at about 80 °C

Three of those overlap in a normal Tuesday dinner, which is the whole argument for this page. Start each one as it goes on, name it, and stop keeping the running order in your head.

Lesson and Station Rotation

Tue, 11 Aug 2026 00:00:00 +0000

Lay out a carousel of stations with a length each, add the changeover time, and see whether the whole rotation fits the period before the class is hal

Lighting a Video Call With Your Screen

Tue, 11 Aug 2026 00:00:00 +0000

Which white

Room	Panel	Why
Household bulbs, evening	Warm 3200 K	Otherwise your face reads blue against the wall
Daylight, or LED panels	Daylight 5500 K	What most webcams are balanced for
Other monitors in shot	Cool 6500 K	Matches the white point of the screens beside it
Very dark room	Pure white, dimmed	Maximum light, then pull it back until it is comfortable

Start at daylight if you are not sure. It is wrong in fewer rooms than either extreme.

Meeting Agenda Timer

Tue, 11 Aug 2026 00:00:00 +0000

Give each agenda item its minutes and see the running total against the length of the meeting — before the meeting, which is the only time it can be f

Metronome

Tue, 11 Aug 2026 00:00:00 +0000

Tempo markings, and the ranges they usually mean:

Marking	BPM	Feel
Largo	40–60	Broad, slow
Adagio	60–76	Slow, at ease
Andante	76–108	Walking pace
Moderato	108–120	Moderate
Allegro	120–156	Fast, bright
Vivace	156–176	Lively
Presto	176+	Very fast

One beat at 60 BPM is exactly one second, which is the number worth remembering: everything else is 60 000 divided by the tempo in milliseconds, and the page shows that figure so you can check a delay setting or a video edit against it.

Military Time Converter

Tue, 11 Aug 2026 00:00:00 +0000

The whole chart, since most visits are really looking for one row of it:

12-hour	Military	12-hour	Military
12:00 AM (midnight)	0000	12:00 PM (noon)	1200
1:00 AM	0100	1:00 PM	1300
2:00 AM	0200	2:00 PM	1400
3:00 AM	0300	3:00 PM	1500
4:00 AM	0400	4:00 PM	1600
5:00 AM	0500	5:00 PM	1700
6:00 AM	0600	6:00 PM	1800
7:00 AM	0700	7:00 PM	1900
8:00 AM	0800	8:00 PM	2000
9:00 AM	0900	9:00 PM	2100
10:00 AM	1000	10:00 PM	2200
11:00 AM	1100	11:00 PM	2300

The trick for the afternoon is subtraction: any military time from 1300 onwards is twelve less in 12-hour form, so 1700 is five o’clock. Before 1200 the two agree, which is why the morning never causes trouble.

Online Alarm Clock

Tue, 11 Aug 2026 00:00:00 +0000

Times can be typed the way you say them, and the awkward hour is worth spelling out:

Typed	Understood as
`6:45 am`	Quarter to seven in the morning
`18:30`	Half past six in the evening
`0645`	The same as 6:45 am
`12:00 am`	Midnight — the start of the day
`12:00 pm`	Noon

Midnight and noon are the only two times where the 12-hour clock behaves the opposite way to instinct, and it is the reason 24-hour notation exists at all — the military time converter shows both sides of it.

Online Stopwatch

Tue, 11 Aug 2026 00:00:00 +0000

Three keys run the whole page, which is the point — a stopwatch you have to aim a mouse at is a stopwatch that is late twice per lap.

Key	Does
Space	Start and stop
L	Take a lap
R	Reset everything

Laps are listed newest first, each with its own split and the running total, so the number you want is at the top rather than at the end of a growing list.

Pomodoro Timer

Tue, 11 Aug 2026 00:00:00 +0000

The standard cycle, and the two that people most often move to:

Cycle	Work	Break	Long break	Suits
Classic	25 min	5 min	15 min after 4	Task lists, admin, code
Deep	50 min	10 min	30 min after 3	Reading, writing, anything slow to enter
Light	15 min	3 min	15 min after 4	A tired head, or starting after a stall

A round is a unit of planning as much as a unit of time. Written as “this will take three rounds”, an estimate becomes checkable in a way that “this will take an hour or two” never does, and the counter on this page is what makes that possible.

What we process

Scheduling Across Time Zones

Tue, 11 Aug 2026 00:00:00 +0000

The weeks to watch

Change	Northern spring	Northern autumn
United States	Second Sunday in March	First Sunday in November
European Union and UK	Last Sunday in March	Last Sunday in October
Australia (southern)	First Sunday in April, back	First Sunday in October, forward
Countries with no change	—	Japan, India, China, most of Africa, Arizona

The mismatch in March is the expensive one: for about three weeks the US is an hour closer to Europe than everybody’s memory says, and a recurring call set months earlier lands an hour out for one side.

Seconds to Minutes

Tue, 11 Aug 2026 00:00:00 +0000

The conversions that come up most, worth knowing without a page:

Seconds	Minutes	Clock
30	0.5	0:30
45	0.75	0:45
60	1	1:00
90	1.5	1:30
100	1.6667	1:40
300	5	5:00
600	10	10:00
3600	60	1:00:00
5400	90	1:30:00
86 400	1440	24:00:00

The row at 100 seconds is the one worth pausing on: it is the case where the decimal and the clock form look least alike, and where copying the wrong one does the most damage.

Sleep Timer

Tue, 11 Aug 2026 00:00:00 +0000

Where the sleep timer lives in the things people actually fall asleep to:

What is playing	Where its own sleep timer is
Spotify	Now playing → the three-dot menu → Sleep timer
YouTube	Settings → Reminders (a bedtime prompt, not a stop)
Apple Music	Clock app → Timer → When Timer Ends → Stop Playing
Podcast apps	Almost all have one on the playback screen
Television	The sleep button on the remote, or Settings → Timers
Android, everything at once	Digital Wellbeing → Bedtime mode

This page is the one to use when what you want darkened is the screen itself — a tablet propped up for a film, a laptop playing something in the corner of a room, a monitor left on in a bedroom.

Study Session Log

Tue, 11 Aug 2026 00:00:00 +0000

Log sessions as they happen and see the real total: how many, how long each, and the hours that add up over a week rather than the ones you meant to d

Time Calculator

Tue, 11 Aug 2026 00:00:00 +0000

Everything below is understood in the two boxes:

Field	Accepted
Time	`9:15 am` · `09:15` · `0915` · `9am` · `21:15`
Length	`45m` · `90 min` · `1h 30m` · `1:30` · `90` (seconds)

A worked example, because it is the case that goes wrong most often: a shift starting at 10:30 pm with eight hours and thirty minutes to run ends at 7:00 am — the next day. The time alone says 7:00, and only the day counter tells you which morning to be there.

Time Card Calculator

Tue, 11 Aug 2026 00:00:00 +0000

Rounding options, and what each is for:

Setting	Step	Where it is used
None	—	The truthful total; check any policy against it
5 minutes	0.083 h	Fine-grained systems
6 minutes	0.1 h	US payroll working in tenths of an hour
15 minutes	0.25 h	The traditional quarter-hour time card

Add or remove days with the buttons; a fortnight is simply more rows, though the forty-hour overtime split only makes sense on a single week.

Time Duration Calculator

Tue, 11 Aug 2026 00:00:00 +0000

The forms this page produces, and where each one belongs:

Form	Example	Used by
h:mm	8:30	Clocks, rotas, anything read by a person
Decimal hours	8.5	Payroll, invoices, hourly rates
Minutes	510	Scheduling systems, parking, cooking
Seconds	30 600	Video and audio, frame counts
Words	8 hours 30 minutes	Reading aloud, writing up

The middle two are where the arithmetic goes wrong most often: 8:30 typed into a decimal field claims eight hours and eighteen minutes, and 8.5 read as a clock time is not a time at all.

Time Zone Converter

Tue, 11 Aug 2026 00:00:00 +0000

Gaps that change during the year, which is most of the useful ones:

Pair	Usual	For a few weeks
New York → London	+5 h	+4 h in March, +6 h in early November
Los Angeles → Berlin	+9 h	+8 h in March
London → Sydney	+9 h	+11 h in the southern summer
New York → Delhi	+9:30 h	+10:30 h in winter
Anywhere → Arizona	fixed	Arizona never moves; everyone else does

The southern hemisphere row is the one that surprises people: Australia’s clocks go forward when Europe’s go back, so the gap moves by two hours rather than one.

Weekly Timesheet Log

Tue, 11 Aug 2026 00:00:00 +0000

A week of shifts kept as a record rather than recalculated from memory: hours per day less breaks, the weekly total in decimal, and what falls past fo

White Screen

Tue, 11 Aug 2026 00:00:00 +0000

The four whites and where each one belongs:

Panel	Roughly	Use it when
Pure white	—	You want maximum light and do not care about tint
Warm	3200 K	The room is lit by household bulbs
Daylight	5500 K	Daytime, or mixed lighting; the safe default on camera
Cool	6500 K	Matching other monitors, or a deliberately crisp look

Keyboard control works in full screen: left and right arrows step through the colours, up and down change the dimming, and escape leaves.

Work-to-Rest Ratios

Tue, 11 Aug 2026 00:00:00 +0000

The ratios, and what each one is for

Ratio	Example	Trains	Feels like
1:3	15 on, 45 off	Speed and power	Short, sharp, plenty of standing
1:2	20 on, 40 off	Speed endurance	Hard efforts, real recovery
1:1	30 on, 30 off	Aerobic and anaerobic together	The classic conditioning session
2:1	40 on, 20 off	Conditioning, muscular endurance	Relentless
3:1	45 on, 15 off	Muscular endurance	A class circuit
2:1 maximal	20 on, 10 off	Both, if truly maximal	Four minutes that feel much longer

The last row is the odd one: the same 2:1 ratio as 40/20 but with efforts short enough to be genuinely maximal, which is what makes Tabata different from a fast circuit.

World Clock

Tue, 11 Aug 2026 00:00:00 +0000

Offsets that catch people out, and why:

Zone	Offset	Note
India	UTC+5:30	One zone for the whole country, on the half hour
Nepal	UTC+5:45	The only quarter-hour zone in common use
China	UTC+8	One zone across five geographic ones
Arizona	UTC−7 all year	Does not observe daylight saving
Australia	UTC+8 to +11	Three zones, one of them on the half hour
Newfoundland	UTC−3:30	Half-hour offset in North America

Add the cities you deal with and the list stays as long as you need it. Nothing is stored, so the set is per visit — which is the trade for a page that needs no account.

World Meeting Planner

Tue, 11 Aug 2026 00:00:00 +0000

Enter each person’s working hours in UTC and see the window where they overlap — the only hours a meeting can actually happen.
