Plan Pomodoro rounds

Use this planner to turn focus and break settings into a predictable Pomodoro sequence. Enter the focus length, the short break length, the long break length, and the number of rounds. Each round contains a focus period. A break is inserted after every round except the final one; after the fourth cycle, the planner uses the long break value.

The processor applies a minimum of one minute to every duration and to the round count. A fractional round count is rounded to a whole number. This is a planning aid that stays local. It does not run a clock, send alerts, or record whether you completed a round.

How the cycle works

A Pomodoro round is one focus period followed, when another round remains, by a break. The first three breaks are short. The break after round four is long, and the same fourth-cycle rule repeats when you schedule more than four rounds.

The schedule is deterministic: the same inputs create the same ordered lines. It does not add a break after the last round, so the output can be copied into a calendar or used beside a separate timer.

Read the sequence

Each Round line is a focus period. A following Break line is the rest before the next round. The fourth-cycle long-break rule is visible in the ordered output.

Choose durations that fit your subject and health needs. A Pomodoro pattern is a planning convention, not a requirement for every learner.

Common mistakes

Do not expect a break after the final round.

Do not confuse shortBreakMinutes with longBreakMinutes; only the fourth-cycle break uses the long value.

Planner limits

The tool does not run a timer, notify you, or save completed rounds.

It does not schedule meals, setup, interruptions, or accessibility accommodations.

Create a Pomodoro plan

  1. Enter focusMinutes for the length of each focus period.
  2. Enter shortBreakMinutes for ordinary breaks.
  3. Enter longBreakMinutes for the break after every fourth round.
  4. Enter rounds, run the tool, and check each focus and break line before beginning.

Pomodoro rules

Focus duration

max(1, focusMinutes)

Every round uses the normalized focus duration.

Break selection

roundIndex % 4 === 0 ? longBreakMinutes : shortBreakMinutes

The break after the fourth round is long; other inserted breaks are short.

Round count

The round input is rounded and clamped to at least one.

The final round has no trailing break.
