What this calculator does
Pomodoro session planner works out how many focused work intervals a task will take, breaks included. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
FormulaPomodoros = ⌈task time / work interval⌉; a long break replaces the short break every n pomodoros
