25 Minute Timer
← All preset timersThe Pomodoro technique fixed its work interval at twenty-five minutes, followed by a five-minute break, and took its name from the tomato-shaped kitchen timer Francesco Cirillo used as a student. That is the whole reason this particular number gets typed so often. It is not a natural unit of anything: it is one method's chosen block, long enough to reach something and short enough that starting feels cheap. This page is the plain interval on its own, twenty-five minutes and one alarm with nothing after it. For the full cycle, with breaks and session counts handled automatically, the Pomodoro timer on this site does that job instead.

Ends with an audible alarm — keep this tab's sound unmuted. A running countdown keeps counting in a background tab and picks itself back up if you reload.

Why 25 minutes
A single interval suits work that does not repeat: one email you have been avoiding, one chapter, one difficult phone call. There is no break waiting at the end and no session count to satisfy, so when the alarm sounds you are simply finished. Twenty-five also works as a shared unit. Two people can hold attention on the same problem for that long before anyone needs to stand up.

FAQ
- How is this different from the Pomodoro timer on this site?
- This page runs one interval and stops. The Pomodoro timer runs the method: a focus block, a short break, another block, and a longer break after a set number of sessions, moving between them on its own. Use this page when you want a single twenty-five-minute stretch and nothing afterwards, and that one when you want the whole cycle managed for you.
- Why twenty-five minutes rather than thirty?
- Because the technique specified twenty-five and the number stuck. There is a tidy argument for it as well: twenty-five plus a five-minute break comes to exactly half an hour, so two intervals fit inside an hour with no arithmetic. A thirty-minute block with a break attached overruns the hour, which makes it awkward to line up against anything on a calendar.
- What happens if I reload the page partway through?
- The countdown survives it. Timer state is kept in the browser, so a refresh, a stray back button, or a tab the browser decided to restart picks up the same countdown instead of resetting to 25:00. Time remaining is worked out from a real timestamp rather than counted tick by tick, so nothing is quietly lost while the page reloads.
