Pomodoro Schedule Planner
Plan your day using the Pomodoro technique. Calculate how many work sessions fit in a time block, with breaks and long-break intervals.
What this calculates
The Pomodoro Technique splits work into 25-minute focused sessions ('pomodoros') separated by 5-minute breaks, with a longer 15-30 minute break every four pomodoros. This planner calculates how many sessions fit in a given time block and what the schedule looks like, helping you plan study or deep-work blocks honestly.
Formula & how it works
Total time = N × (work + short_break) − short_break + long_break_count × long_break_extra. With 4-cycle long break: every 4 pomodoros add (long − short) extra minutes. Default: 25 work / 5 short / 15 long every 4. Variations: 50/10 'extended' is popular for harder cognitive work; 90/15 matches one ultradian cycle.
Worked example
4-hour study block. With 25/5 pomodoros + 15-min long break every 4: pomodoro 1 (25w + 5b) → pomodoro 4 (25w + 15 long b instead of 5) → continue. In 240 minutes: ~7 pomodoros = 175 min focused work + 65 min breaks. Surprisingly little raw work; that's the lesson.
Frequently asked questions
Is 25 minutes really enough?
It's a starting point. Cal Newport and others argue for longer blocks (50-90 min) for deep work. The pomodoro 25 minutes works well for distractible work like email, studying flashcards, or shallow tasks. Adjust to your task.
Why a long break every 4?
Sustained focus depletes attention. The longer break lets prefrontal cortex recover. Without it, sessions 5-8 typically perform worse than sessions 1-4 — verified in attention research.
Does this work for everyone?
Mixed. Highly structured, time-anxious people love it. Flow-state workers find the timer disruptive. Try it for a week before deciding.
What about ADHD?
Often works well — external structure compensates for internal time-blindness. Some users prefer shorter blocks (15-20 min) and longer breaks (10 min). Experiment.
