Press start and this timer counts down 13 minutes, then sounds an alarm.

A 13-minute timer is handy for meditation, short study sprints, breaks, and quick chores. That's 780 seconds.

How it works

This page is preset to 13 minutes — just press Start and it counts down to zero, then sounds an alarm even if you switch tabs (the tab title shows the time left). Pause and resume anytime, or Reset to start over. Space starts and pauses.

Need a different length? Try the 12-minute timer or 14-minute timer, or set any hours, minutes and seconds above. Counting down to a date instead? Make a countdown; to time how long something takes, use the stopwatch.
