Time blocking planner
Plan a day by fitting your tasks into the time left around fixed commitments. Higher priority tasks go first, and anything that does not fit is listed.
Up to 200 tasks of 1 to 1,440 minutes, 20,000 characters, and 50 fixed commitments in 5,000 characters. Everything is calculated on your device. Downloads: JSON report, CSV and an iCalendar (.ics) file. One row per task. Priority is 0 to 9, highest first. Splittable is true or false. Up to 20,000 characters. Review the settings before running.

How to use Time blocking planner
- Paste one row per task with its minutes, a priority from 0 to 9 and whether it can be split.
- Choose the day, its start and end time and your time zone.
- List fixed commitments such as meetings and lunch, one per line.
- Review the timeline and the unplaced tasks, then download the calendar file, CSV or JSON report.
Useful next steps
How tasks are placed
Fixed commitments are removed from the working day first. Tasks are then placed in priority order, highest first, keeping your row order for equal priorities. A task that cannot be split goes into the first free gap long enough to hold it. A task that can be split fills free gaps from the start of the day in pieces no shorter than your minimum, and is left out whole if the day cannot hold all of it.
Not an optimal plan
This is a simple first-fit method, so a different order could sometimes fit more tasks. Unplaced tasks are listed with the reason, so you can shorten, split or move them.
Calendar file
Only the task blocks go into the calendar file, because your fixed commitments are usually already in your calendar. Times are written in UTC so calendar apps show them at the right local time.
