30 Minute Timer
The 30 minute timer
Half an hour is the default unit of a working day: one meeting, one workout, one solid stretch of study.
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 30 minute is good for
What people actually use this length for:
- A thirty-minute meeting with a visible finish
- A run, a class or a gym session
- Slow-cooked dishes at the halfway check
- A study block for a subject you find hard
- Screen-time limits for children, agreed in advance
A countdown on the shared screen ends meetings on time more reliably than any agenda.
Other timers
Need a different length? Try 20 Minute Timer, 25 Minute Timer, 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.

This is the 30 minute 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 and time zones has every country and city.
