What a 15 Minute timer is good for
- The longer break after four Pomodoro blocks, usually 15 to 30 minutes.
- Timed quizzes in class, shown big on the projector so nobody has to ask.
- Daily stand-up meetings that should not run over.
Press Start and the countdown runs for exactly 15 minutes. It shows in the tab title too, so you can work in another tab and still see the time left. When it reaches zero, a gentle alarm plays and the dial flashes until you stop it.

Frequently asked questions
How many seconds are in a 15 Minute timer?
900 seconds. The 15 Minute timer counts them down from 15:00 and plays an alarm at zero.
Will the 15 Minute timer ring if I switch tabs?
Yes. The timer works from the moment it should end, not from ticks, and the alarm is scheduled on the browser's audio clock, which keeps running in background tabs. Keep the sound on and the tab open.
Can I change the 15 Minute timer to a different length?
Yes. The hours, minutes and seconds fields and the presets work as usual. This page only starts at 15 minutes; every other length is one tap away, or open one of the timers linked below.
