25 Minute Timer
A 25 minute timer counts down 1,500 seconds and sounds an alarm when it reaches zero. That is 0.42 decimal hours on a timesheet, or 41.67% of an hour.
A twenty-five minute timer is the work block of the Pomodoro Technique, and the single most used focus interval in any study method.

What a 25 minute timer is used for
The Pomodoro work block, study sessions and single-task focus.
- One Pomodoro
- Twenty-five minutes of work followed by five minutes of rest is the original ratio, with a longer break after four rounds.
- Single-task focus
- Twenty-five minutes is long enough to make real progress and short enough that starting never feels like a commitment.
- Study blocks
- Twenty-five minutes maps well onto one topic, one problem set or one section of reading.
- Timeboxed admin
- Bounding email, invoicing or filing to twenty-five minutes stops open-ended admin from eating a morning.
Getting a full twenty-five minutes of focus
Decide what the block is for before you press start, and write it down. Close whatever will pull you away: the email tab, the chat window, the phone lying face up on the desk. Twenty-five minutes goes quickly when the first five are not spent choosing what to work on.
If a stray thought or task comes up mid-block, jot it on paper and keep going. When the timer ends it offers the matching five minute break, and the 25/5 Pomodoro timer runs the whole cycle for you, including the longer break after four rounds.

Your focus time, counted and kept
A countdown tells you when the block ends. PomoTodo records that the block happened, which task it went to and what the week added up to, so a month of 25 minute blocks becomes something you can actually look at.
Free plan tracks unlimited focus time across unlimited tasks. No card required.
Timers either side of 25 minutes
If 25 minutes is the wrong length, the two nearest are 20 minutes and 30 minutes.

Questions about the 25 minute timer
Is a 25 minute timer the same as a Pomodoro timer?
A Pomodoro timer is a 25 minute timer plus the cycle around it: a five minute break after each block and a longer break after four. This page is the plain countdown. If you want the breaks and the round counter handled automatically, use the 25/5 Pomodoro timer instead.
Why is the Pomodoro block twenty-five minutes?
Francesco Cirillo picked it with a kitchen timer while studying in the late 1980s, and it stuck because it fits most tasks most of the time. There is nothing special about twenty-five beyond that balance, and plenty of people work better at fifty.
What counts as one Pomodoro?
One uninterrupted twenty-five minute block spent on a single task. In Francesco Cirillo's method, a block that is abandoned partway through does not count, and you start a fresh one rather than finishing the old one later.
