What people set 15 minute timers for

Fifteen minutes is long enough to be useful and short enough that starting is easy, which is why it is the standard advice for beating procrastination. Commit to fifteen minutes of the thing you are avoiding and the hard part is already behind you.

Need a different length? The countdown timer takes any duration up to 12 hours, and the pomodoro timer handles work and break cycles for you.

Frequently asked questions

How do I start the 15 minute timer?
The timer loads preset to 15 minutes — press Start (or the Space bar) and it counts down immediately, showing the exact wall-clock time it will finish.
Will it still ring if I switch tabs?
Yes. The deadline is anchored to your system clock rather than counted in ticks, so browser throttling can't delay it. The remaining time also shows in the tab title.
Can I change the duration?
Yes — presets from 1 to 60 minutes are one click away, and the custom field takes anything up to 12 hours.
