How to use the pomodoro calculator

  1. Enter how many minutes you have available in total.
  2. Enter the length of each work session, short break and long break (the defaults of 25/5/15 min are the classic Pomodoro Technique).
  3. Enter how many work sessions should pass between each long break.

What is the Pomodoro Technique?

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The principle is simple: work focused for one session (traditionally 25 minutes), then take a short break. After a set number of sessions (usually four), you take a longer break before starting again.

The calculator simulates this cycle within the time you have available, and works out how many complete work sessions fit, including all the breaks that fall within that time.

Note: The calculator only counts whole, completed work sessions — a session that's started but doesn't finish within the time frame isn't counted.

Frequently asked questions

Do I have to use exactly 25 minutes per session?

No, 25 minutes is the classic Pomodoro length, but many people adjust it based on their own attention span and the type of task — some use 50-minute sessions with longer breaks, others use shorter sessions for tasks that require less sustained focus.

Why are breaks an important part of the technique?

Regular breaks help maintain concentration and avoid mental fatigue over longer work periods. The long breaks after several sessions provide more thorough recovery than the short breaks between individual sessions.

What if I don't have time for a full work session at the end?

The calculator only counts the whole, completed sessions and shows how much time is left over. You can use this remaining time for a shorter, informal work period, or just leave it as a buffer.
