Time Blocking That Can Survive an Interrupted Day
By myhacks editorial team · Method and sources reviewed 27 August 2026.
Quick Answer
Time blocking assigns categories of work to real calendar space. The useful version includes buffers and expects the plan to be redrawn when reality changes.
A task list describes inventory; a calendar exposes capacity. Cal Newport’s published method assigns work to blocks and explicitly allows the schedule to be revised after interruption. The goal is intention about time, not obedience to the first draft.
Key Points
- Plan from fixed commitments and capacity, not from the full wish list.
- Use blocks for both focused and reactive work.
- Leave buffer around uncertain work.
- When the day changes, redraw the remaining blocks instead of abandoning the method.
How to Implement
- 1Mark meetings, care obligations, meals and shutdown time.
- 2Choose one high-value block before placing administrative work.
- 3Batch communication into one or more explicit reactive blocks.
- 4Leave at least one unassigned buffer block.
- 5At the first major disruption, make a new plan for the remaining hours.
Pro Tip
Track the difference between planned and actual duration for one week. Better estimates are a more durable gain than squeezing in one extra task.
