1 Hour Timer

The one hour timer

An hour is the longest block most people can work on one thing well. Set it, put the phone away, and let the countdown handle the clock-watching.

Press start and the ring empties as the time runs down. The remaining time also appears in the tab title, so you can work in another window and still see it. When it reaches zero the tone plays until you stop it.

What one hour is good for

What people actually use this length for:

  • A full deep-work or study session
  • Slow cooking, roasting and proving dough
  • An hour-long class, workshop or client call
  • A long training session with a hard stop
  • Timed exam practice at full paper length

For an hour of work, plan the break before you start. Ending a session with no plan is how an hour turns into three.

Other timers

Need a different length? Try 40 Minute Timer, 45 Minute Timer, or set any duration on the timer hub.

Questions people ask

Does the timer keep running if I open another tab?

Yes. It works from the finishing moment rather than counting ticks, so background throttling does not slow it down.

Can I change the sound?

Fifty tones are listed beside the timer, from a soft chime to a klaxon. Your choice is remembered on this device.

Will it start automatically?

Only if the site is set that way. Otherwise press start when you are ready — which is usually what you want for a preset timer.

Where to go next

This is the 1 hour timer — its own page, so you can bookmark it or send the link to someone rather than setting the duration again. If you need the time somewhere else rather than a timer, world clock time has every country and city.
