15 Second Timer
Press start and this timer counts down 15 seconds, then sounds an alarm.
A 15-second timer is handy for quick breathing resets, a dental rinse, or rest between sprints. That's 15 seconds.

How it works
This page is preset to 15 seconds — 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 30-second 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.
