Why a 15 minute time blocking timer works
- Turns a list into a schedule
- Four blocks equals one planned hour
- Leave gaps for the overspill
Quarter-hours are the smallest unit a calendar handles without arithmetic. Four of them make a planned hour, which is a different thing from an hour that merely passed.
How to spend the fifteen minutes
| Minute | What to do |
|---|---|
| 0-3 | Look at tomorrow's real available hours |
| 3-12 | Assign every hour a specific job |
| 12-15 | Leave two gaps for the overspill |

Questions people ask
How do 15 minute blocks fit into time blocking?
They are the smallest useful unit. Use them for admin, calls and reviews, and reserve 45 to 90 minute blocks for work that needs a long run-up.
What if I get interrupted?
Note where you were in four words and restart the block. A broken fifteen minutes is not worth salvaging, but the note means you lose seconds rather than minutes.
Do I need to plan anything before starting the 15 minute time blocking timer?
Decide the single task first and say it out loud. A block that starts with 'what should I do' loses its first three minutes, which is a fifth of the session.
