How to fill in the sheet
Use separate columns for the date, recorded bedtime, waking time and personal observations. When a recorded period crosses midnight, make clear which date each endpoint belongs to.
How to keep it useful
The difference between two times describes a recorded interval; it does not by itself establish time spent asleep. The sheet stores notes without interpreting sleep quality or setting clinical targets.
Write recognizable actions
“Organize” is hard to mark complete; “file the papers on the desk” has a clear ending. Leave room for unexpected tasks and review unfinished items before copying them into the next day. Remove tasks that are no longer needed.
