About this 20 second timer

Twenty seconds is the classic hand-washing length, and the work interval of a Tabata round. For rounds and intervals with rest, try the Round Timer.

Good for:

  • Washing your hands: health agencies advise scrubbing for at least 20 seconds
  • Tabata-style work intervals (20 seconds on)
  • A short stretch or calf raise hold
  • Speed rounds in party games

How it works

The page opens with 0:20 ready in the big view. Press Start (or Space on a keyboard) to begin, and again to pause. When time is up an alarm rings until you press Stop, or +1 min for a little longer. Close the big view for more timers, a stopwatch and countdowns.

It keeps the right time with the tab in the background and after a reload. Phones may pause a page while they're locked, so keep this page open (or turn on Keep screen on in Settings) for an alarm you can't miss. Nothing is uploaded and there's no account.
