Where is midnight on the circle?
At the top. The circle runs clockwise like a clock: 6:00 on the right, noon at the bottom, 18:00 on the left.
How do I enter sleep that runs overnight?
Enter it as is, e.g. start 23:00, end 06:30. An end time before the start is treated as overnight and drawn as a 7 h 30 min slice.
What happens when activities overlap?
The later activity is drawn on top and the Summary lists the overlapping time ranges, so typos and double bookings stand out.
What is the blank circle?
A printable circle with only the hour marks and the numbers 0, 3, 6 … 21 – no slices. Handy for handwritten homework or for kids to color in themselves.
Where can I use the saved image?
PNG pastes into Word, Google Docs and blogs. SVG stays sharp at any size and can be edited in Illustrator or Figma.
