Pomodoro Session Calculator

About this calculator

The Pomodoro Technique, created by Francesco Cirillo in the late 1980s and named after the tomato-shaped kitchen timer he used as a student, structures work into fixed 25-minute focused intervals called “pomodoros,” each followed by a 5-minute break, with a longer 15-to-30-minute break inserted after every fourth pomodoro to prevent mental fatigue from accumulating.

Students, writers, developers, and other knowledge workers use this rhythm to combat procrastination and task-switching fatigue, because committing to a short, bounded interval lowers the psychological barrier to starting a task and the scheduled breaks prevent the burnout that comes from working in undefined, open-ended stretches.

Enter how long your task is expected to take, and this calculator breaks it into the number of pomodoro cycles needed along with the total elapsed time once the built-in short and long breaks are included.
