Pomodoro Timer: 25-Minute Focus Sessions and Breaks

Run 25-minute focus sessions, then take a 5-minute short break or a longer break, following the Pomodoro method.

The Pomodoro Technique: timings, a full cycle and using the timer

The Pomodoro Technique, created by Francesco Cirillo, splits work into 25-minute sessions separated by a short break, with a longer break every four sessions. The timer offers three fixed durations: 25 minutes of focus, a 5-minute short break and a 15-minute long break. A four-session cycle therefore takes 2 h 10 min.

How a cycle runs

  1. Pick a task and start Focus mode (25:00).
  2. At the alarm (two beeps), switch to Short break (05:00).
  3. Repeat Focus + Short break three times.
  4. After the fourth Focus, choose Long break (15:00).

Example: 4 × 25 min of work + 3 × 5 min short breaks + a 15-minute long break = 130 minutes, or 2 h 10 min per full cycle, of which 100 minutes are focused work (77% of the time).

What the timer does

  • The three durations are fixed at 25, 5 and 15 minutes.
  • You switch modes by hand: the tool does not count sessions or move to the break automatically. The tip mentions a 15 to 30-minute long break; the timer counts 15.
  • Changing mode resets and stops the countdown.
  • The remaining time is recalculated from the scheduled end time, so it stays accurate when the tab is in the background and the browser slows scripts down.
  • The end is signalled by two 880 Hz beeps if the device sound is on.

In the original method an interrupted session does not count: you restart it rather than pausing it.

Frequently Asked Questions

How long is a pomodoro?

A pomodoro is 25 minutes of uninterrupted work, followed by a 3 to 5-minute short break. The timer uses 25 minutes of focus and a 5-minute break.

When should you take the long break in the Pomodoro Technique?

After four pomodoros, take a long break of 15 to 30 minutes. The timer offers a fixed 15-minute long break that you start yourself after the fourth session.

How many pomodoros can you do in a day?

A cycle of four pomodoros with its breaks takes 2 h 10 min (100 minutes of work). An 8-hour day therefore allows about 14 pomodoros, breaks included.

What should you do if you are interrupted during a pomodoro?

In the original method an interrupted pomodoro does not count: note the interruption to deal with later, then start a full 25-minute session again. The tool's reset button is there for that.
