20 Minute Timer
Press start and this timer counts down 20 minutes, then sounds an alarm.
A 20-minute timer is handy for a power nap, a focused study block, or a HIIT workout. That's 1,200 seconds.
How it works
This page is preset to 20 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 19-minute timer or 21-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.
