The Zero-Based Calendar
Plan every hour of the day, including rest, so nothing drifts and nothing is left to chance.
Group similar tasks into one block: fewer context switches, more done, less mental tax.

Time batching means doing similar tasks together instead of one at a time across the day. All your email in one sitting, all your calls in another, all the small admin in a third. Every switch between kinds of work costs a little attention, and batching pays that cost once instead of twenty times.
1Group by kind of work
Collect tasks that use the same mental mode: messages, calls, writing, errands, admin. Three or four batches cover most days.
2Give each batch a block
Put the batch on the calendar at a time that suits the mode: calls after lunch, writing in your peak hours. Batching decides what, the block decides when.
3Run the batch with a timer
Treat the batch like a short sprint. A timer sets a clear end, which keeps a quick look at email from eating the afternoon.
4Protect it from drips
Silence notifications outside the batch. A batch only saves the switching cost if the day does not keep interrupting it.
Time blocking decides when you work on something; time batching decides what you group into that time. They fit together: batch your email, then block a slot for the batch. Blocking without batching still leaves you hopping between kinds of work inside each block.
Plan every hour of the day, including rest, so nothing drifts and nothing is left to chance.
Stop putting it off: one task, 25 focused minutes, a short break, then repeat.
Timers, tasks and teams in one calm place. Free to start, no card required.
