Set the timer to 24 seconds

00:00:00

How to use the online timer

Box breathing and other calming exercises work in blocks, and 24 seconds is a common length for the exhale or hold phase without a coach counting you through it aloud. Set it running, close your eyes if that helps, and let the countdown replace the mental tally you'd otherwise lose track of after a few rounds. It's a small tool, but it takes the guesswork out of pacing yourself.

Hit Start whenever you're ready and the timer runs on its own from there, no further clicking required until it finishes. It only counts while the tab stays open, so leave it running in the background rather than closing the browser or navigating away if you need the time to stay accurate. Once it reaches zero, an alarm sound lets you know without you having to keep checking the page.

There's something to be said for a timer that doesn't try to sell you a premium version or bury the start button behind ads you have to swipe past. This one lives in a browser tab, plain and straightforward, doing exactly what it says and nothing else. You can leave the tab minimised while you get on with things, and it'll keep counting until it's time to let you know. People type this as set timer 24 seconds or timer for 24 seconds; both land here and start the same count.

Common questions

Does the timer make a sound when it finishes?

Yes, an alarm plays once it reaches zero, provided your device's volume is turned up and the tab hasn't been muted.

Can I pause the timer partway through?

Yes, pause and resume are both available, so you can stop the count if you're interrupted and pick up again exactly where you left off.

Can I set a custom time instead of the preset?

Yes, most pages let you adjust the minutes and seconds directly, so you're not limited to the exact length shown in the page title.

Does the timer work without an internet connection?

The page needs to load once, but the countdown itself runs locally in your browser, so a dropped connection partway through won't stop it.
