25 Minute Timer

The short answer

A 25 minute timer counts down 1,500 seconds and rings at zero. Press Start above to begin. Twenty-five minutes is one classic Pomodoro: a focused round of work followed by a 5-minute break, with a longer break after four rounds. Use this timer for one round, or the Pomodoro timer for full cycles.

What fits in 25 minutes?

Twenty-five minutes is one focused round. Pick a task you can see the end of, and write it down before you press Start.

• One Pomodoro of focused work. One task, notifications off, distractions jotted on paper for later. For rounds and breaks in one place, use the Pomodoro timer.
• A homework or reading section. Read one section, then close the book and write what you remember. Starting is the hard part; see how to stop procrastinating on studying.
• Clear the inbox. Reply, file or delete every message until the timer rings, then stop.
• A full kitchen clean. Dishes, counters, stovetop and the floor. Music helps.
• A home workout. Five minutes of warm-up, 15 minutes of bodyweight circuits, five minutes of stretching.

How to use the 25 minute timer

1. Press Start. The timer is already set to 25 minutes. The space bar starts and pauses it too.
2. Need a different time? Type it in the box, such as 7, 7m 30s or 7:30, and press Set. Or tap another preset.
3. Make it big. Full screen (or F) shows only the countdown. Kids view shows a big colored disk that shrinks as time runs out.
4. When it rings, press Stop alarm or the space bar. Restart runs the same 25 minutes again; +1 min snoozes for a minute.

The timer saves the moment it will end on your device, so it stays accurate in a background tab and after a reload, and the time left shows in the tab title. The page has to stay open for the alarm to play.

Frequently asked questions

Why is a Pomodoro 25 minutes?

Francesco Cirillo, who created the Pomodoro Technique in the late 1980s with a tomato-shaped kitchen timer, used intervals of typically 25 minutes, then a short break. The length is a convention, not a proven optimum; use what you can finish without drifting.

What should I do after 25 minutes?

Take a 5-minute break: stand up, drink water and look away from the screen. After four rounds, take a longer break of 15 to 30 minutes. The Pomodoro timer on this site switches between rounds and breaks automatically.

Is 25 minutes better than 50 for studying?

Neither is proven better. In a study of 87 students, fixed break schedules went with less fatigue and more concentration than self-timed breaks. Start with 25 minutes if starting is hard, and move to 50 once you warm up easily.
