Why 30 minutes?
Thirty minutes is where a daily practice starts to feel like training rather
than a break. Retreats and most traditional courses treat half an hour as the base
unit of a serious sit.
Long sits are easier with a checkpoint: set the interval bell to ten minutes
and you get two gentle marks on the way. There is no prize for sitting longer than
you can honestly keep up.
How to use this page
Choose your bell and interval options above, press Begin sitting, and close your
eyes. The 30-minute timer starts immediately after a short preparation countdown,
opens with one bell strike, and closes the sit when time is up. Keep the tab open —
the timer keeps accurate time even in a background tab, and on laptops it can keep
the screen awake while you sit.
Is this 30-minute meditation timer really free?
Yes — every timer on this site is free, with no account and no ads on the timer itself. Your session history is stored only in your own browser.
Will the bell still ring if I switch tabs during my 30-minute sit?
Yes. The timer is anchored to the clock, not to the tab, so background tabs do not slow it down. Audio plays when the interval or closing bell fires.
Can I change the bell sound on the 30-minute timer?
You can choose a Tibetan bowl, a zen gong, or a soft chime, and add optional interval bells every 1–10 minutes. All sounds are synthesized in your browser — there are no audio files to download.
