Pomodoro Session Calculator: Plan Your Deep Work Day
The Pomodoro Technique works because it turns an overwhelming workload into a series of finite, achievable sprints. But most people just start a 25-minute timer without thinking about how many sessions they need, how long breaks should be, or whether the day’s goal is actually achievable. This calculator does that planning upfront.
Pomodoro Session Calculator
Plan your focus sessions to fit your available work time.
Francesco Cirillo developed the original Pomodoro Technique in the late 1980s using a tomato-shaped kitchen timer (pomodoro is Italian for tomato). The 25-minute session was not scientific — it was simply the interval that worked for him. Research on attention and cognitive fatigue suggests most people can sustain deep focus for 25-90 minutes before productivity drops. Experiment to find your optimal session length.
