productive_time = sessions_needed * session_minutesTotal Wall Time
total_wall_time = sessions_needed * session_minutes + short_breaks * short_break + long_breaks * long_breakVariables
| Variable | Description | Default |
|---|---|---|
total_task_hours | Total Work Needed(hrs) | 6 |
session_minutes | Session Length(min) | 25 |
short_break | Short Break(min) | 5 |
long_break | Long Break (every 4 sessions)(min) | 15 |
sessions_needed | Derived value= ceil(total_task_hours * 60 / session_minutes) | calculated |
short_breaks | Derived value= sessions_needed - floor(sessions_needed / 4) - 1 | calculated |
long_breaks | Derived value= floor((sessions_needed - 1) / 4) | calculated |
How It Works
The Pomodoro Technique
Work in focused bursts (typically 25 minutes) with short breaks between sessions and a longer break every 4 sessions.
Structure
1. Work for the session length (default 25 min) 2. Take a short break (default 5 min) 3. Every 4 sessions, take a long break (default 15 min) 4. Repeat until done
Worked Example
6 hours of work using standard 25/5/15 Pomodoro.
- 01Sessions needed = ceil(360 / 25) = 15 sessions
- 02Short breaks = 15 - 3 - 1 = 11 breaks x 5 min = 55 min
- 03Long breaks = floor(14 / 4) = 3 breaks x 15 min = 45 min
- 04Productive time = 15 x 25 = 375 min
- 05Total wall time = 375 + 55 + 45 = 475 min (7h 55m)
Frequently Asked Questions
Why does the Pomodoro technique work?
Frequent breaks prevent mental fatigue, the timer creates urgency, and the structure reduces procrastination. It also makes large tasks feel manageable.
Can I adjust the session length?
Absolutely. Some people prefer 50/10 or 45/15 splits. Experiment to find what sustains your focus best.
What should I do during breaks?
Stand up, stretch, get water, look away from screens. Avoid checking social media or starting new tasks that could extend the break.
