Pomodoro guide
What is the Pomodoro Technique?
The Pomodoro Technique is a time-management method that divides work into focused sessions and planned breaks. A classic cycle uses 25 minutes of focused work followed by a 5-minute break, with a longer 15-minute break after four focus sessions.
Each focus interval is called a pomodoro. The short deadline can make a task easier to start, while regular breaks create a repeatable rhythm for studying, writing, coding, and other concentrated work.
How to use it
Use this free online Pomodoro timer
Choose one task, start the 25-minute focus timer, and work on only that task until time is up. Take the 5-minute short break, then begin another focus session. After four completed focus sessions, take the longer break before starting a new cycle.
ClockHorizon runs in your browser with no installation. Use the classic 25/5 preset or adjust focus, short-break, and long-break durations to fit your attention span and workload. You can also save custom presets for routines such as 50 minutes of deep work followed by a 10-minute break.
Choose your intervals
How long should a Pomodoro session be?
Start with the classic 25-minute focus and 5-minute break pattern. If 25 minutes interrupts deep concentration, try a longer 45/10 or 50/10 cycle. For difficult tasks or a shorter attention span, begin with a smaller focus block and increase it gradually.
The best interval is one you can repeat without skipping breaks. Keep breaks restorative: stand up, stretch, rest your eyes, or get water, then return when the next focus session begins.
