Daily Planner

One day, hour by hour

A single day broken into hourly slots, with sunrise and sunset marked, the week number, and the day's position in the year.

Questions people ask

The things that come up about daily planners, answered plainly.

What is the day of the year?

Its ordinal position — 1 January is day 1 and 31 December is day 365, or 366 in a leap year. It is what ISO 8601's ordinal date format uses: 2024-198.

Can I change the hours shown?

Yes — set the start and end of the day, and the grid rebuilds. The default runs from 07:00 to 22:00, which covers most people's usable day.
