The Pomodoro Technique alternates short, intense work intervals with mandatory rests so attention does not collapse. This timer ships with the canonical 25-minute focus and 5-minute short break, plus a 15-minute long break that triggers automatically every fourth session. Each duration is editable on the page.

How the Pomodoro Timer Works

The countdown is driven by absolute timestamps, so background tabs and system sleep do not skew the remaining time. The session counter persists for the page lifetime and rotates focus → short break → focus → long break in the correct ratio. There is no audio cue and no system notification — keep the tab visible, or pair with a browser notification extension if you need one.

Frequently Asked Questions

What is the Pomodoro Technique?

A time-management method developed by Francesco Cirillo in the late 1980s: 25 minutes of focused work followed by a 5-minute break, repeated four times, then a longer 15–30 minute break. The interval is short enough to commit to and long enough to make real progress.

Why 25 minutes?

Cirillo chose it as the longest stretch most people can hold sustained focus without micro-breaks. There is nothing magical about the number — feel free to lengthen it for deep coding work or shorten it for shallow tasks; both fields are editable on this page.

Does the timer keep running if I switch tabs?

Yes. The countdown is driven by absolute timestamps, not a 1-second interval, so background-tab throttling does not slow it down. You will get the correct remaining time when you return.

Will it notify me when a session ends?

The page updates the timer and rotates to the next mode automatically, but it does not play a sound or fire a system notification. Keep the tab visible or use an audible browser notification extension if you need an alert.
