TimerPlanTime plans and logs
A timer answers one question and forgets it. These sheets keep the answer: intervals, an agenda that must fit the hour, a week of shifts, the hours everyone is awake.
Interval and HIIT Plan
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.
Lesson and Station Rotation
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 halfway through it.
Meeting Agenda Timer
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 fixed.
Study Session Log
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 do.
Weekly Timesheet Log
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 forty.
World Meeting Planner
Enter each person's working hours in UTC and see the window where they overlap — the only hours a meeting can actually happen.
Free to use, Pro to keep
Every tool on this page works straight away, with no account and no limit on how often you use it. Put your numbers in and you get the answer, the same as on the rest of the site.
What Pro adds is memory and reach. It saves a setup to your account so it is there on your phone as well as the machine you built it on. It turns a result into a page you can send to somebody. It emails you when a date you set is coming, instead of leaving that to your own memory. And it takes the ads off — here and on every other site we run, on one subscription.
A countdown is a moment; a plan is a shape. Interval training, a lesson carousel, a meeting agenda and a timesheet are all the same problem — several lengths that have to add up to something — and none of them fits in a timer that holds one number.
