How to use the Sleep Duration Schedule Calculator
Plan a clock schedule using a duration chosen by you. The day-offset row distinguishes previous-day and same-day bedtimes instead of hiding midnight rollover.
The calculation
Worked example
A 07:00 wake time, eight hours of chosen sleep and 15 minutes to fall asleep give a 22:45 bedtime on the previous day.
Assumptions and limits
No guaranteed sleep cycles, refreshed waking or individualized medical sleep recommendation. Time zones and daylight-saving changes across the night are excluded.
