About Countdown Timer

Pick a preset or type hours, minutes and seconds, then start. The time left is shown in the page and in the browser tab's title, so you can see it from another tab, and you can add a minute while it runs.

The countdown is worked out from the moment it will end, so a slowed-down background tab does not make it drift. The chime and optional notification need this tab to stay open, and may arrive a moment late if the browser has put the tab to sleep.

How to use it

  1. 1Choose a preset or type hours, minutes and seconds.
  2. 2Press Start, or the Space key.
  3. 3Pause, resume or add a minute while it runs.
  4. 4When the chime sounds, press Reset to run the same time again.
