Timeblocking (or time blocking) or time chunking[1] is a productivity technique for personal time management where a period of time—typically a day or week—is divided into smaller segments or blocks for specific tasks or to-dos. It integrates the function of a calendar with that of a to-do list. It is a kind of scheduling.[1]

When done properly, timeblocking can help eliminate distractions and discourage unproductive multitasking.[1][2][3]

Description
The original technique has six steps:[4]

Decide on the task to be done.
Set the Pomodoro timer (typically for 25 minutes).[1]
Work on the task.
End work when the timer rings and take a short break (typically 5–10 minutes).[5]
Go back to Step 2 and repeat until you complete four pomodori.
After four pomodori are done, take a long break (typically 20 to 30 minutes) instead of a short break. Once the long break is finished, return to step 2.
