The 25 minute timer and the Pomodoro technique

25 minutes is the traditional length of one Pomodoro, the focus session at the heart of the technique created by Francesco Cirillo. You pick one task, work on it with no interruptions until the alarm, and then take a five minute break.

After four sessions you take a longer break. Over a morning this rhythm gives you around two hours of real, undistracted work and plenty of recovery time.

  • Choose one task and write it down before you press Start.
  • Silence notifications and keep your phone out of reach.
  • Note any distraction on paper and deal with it after the session.
  • Take a 5 minute break when the alarm sounds, no screens.

Frequently asked questions

How many seconds are 25 minutes?

25 minutes equal 1,500 seconds, which is 25 minutes or 0.42 hours.

Why is the Pomodoro 25 minutes?

It is long enough to make progress and short enough to stay focused. Cirillo used a 25 minute kitchen timer as a student. If it does not suit you, try 50 minutes of focus and a 10 minute break.

Will the 25 minutes timer keep running if I switch tabs?

Yes. The countdown is based on your device clock, so it stays accurate when the tab is in the background. Keep the tab open and your device awake so the alarm can sound.

Can I pause the 25 minutes timer and resume it later?

Yes. Press Pause to stop the countdown and Resume to continue with the remaining time. Reset takes you back to the start.

Can I change the alarm sound?

Yes. Open the Sound / Message settings under the timer to pick a sound, preview it and add a custom message. Your choice is remembered in your browser.
