20 Minute Timer

Twenty minutes works as a medium-sized block: a study session, a stretch of reading, a pot of something simmering or the gap between laundry cycles. This page starts counting the moment it opens.

It rings with a repeating beep at zero and displays the remaining time in the tab title.

How to use this tool

1. Open the page; the 20:00 countdown starts on its own.
2. Use Pause or Space to stop and resume the clock.
3. Press Restart (R) to begin another twenty minutes.
4. Stop the alarm with Stop or any key, or press +1 minute to continue.

A reminder for your eyes

The American Academy of Ophthalmology describes the 20-20-20 rule for screen work: every 20 minutes, look at something about 20 feet away for at least 20 seconds. Start this timer when you sit down, glance away at the beep, then press Restart to begin the next stretch.

Study and reading blocks

Twenty minutes is long enough to get through a chapter section or a set of practice problems and short enough that distraction rarely wins. Put the phone out of reach, work until the beep, then decide whether to continue for another block.

If you prefer a structured pattern with breaks built in, the Pomodoro timer can be adjusted to a 20-minute focus period.

Chores and cooking

Laundry cycles, a slow simmer, marinating or letting bread proof can all run on a twenty-minute cycle. Set the timer when you start, do something else in the meantime and return when it rings.

Light stretching

Gentle yoga flows or a mobility routine commonly last about this long. Prop the screen where you can hear it, and you will not need to watch the time.
