40 Minute Timer
A 40 minute timer counts down 2,400 seconds and sounds an alarm when it reaches zero. That is 0.67 decimal hours on a timesheet, or 66.67% of an hour.
A forty minute timer is the work block of the Animedoro method and the length of a standard secondary school lesson.

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 40 minute blocks becomes something you can actually look at.
Free plan tracks unlimited focus time across unlimited tasks. No card required.

What a 40 minute timer is used for
Longer focus blocks, lessons, and deep tasks that need a warm-up.
- The Animedoro work block
- Forty minutes of work followed by a twenty minute episode, a ratio built for tasks where twenty-five minutes barely gets you started.
- School lessons
- Forty minutes is a common period length in secondary schools, chosen to fit attention span against timetable arithmetic.
- Writing and editing
- Forty minutes is long enough to get past the warm-up phase that makes short blocks unproductive for writing.
40 minutes in other units
- 40 minutes is 2,400 seconds.
- On a timesheet, it is recorded as 0.67 decimal hours.
- It is 66.67% of an hour, or 2/3 of one.

- Against the classic twenty-five minute Pomodoro, it is 1.6 blocks.
Converting a different length is what the minutes to decimal hours converter is for, and adding several together is what the hours calculator does.
