Sleep Calculator

Sleep is not a spreadsheet, but gentle math can nudge you toward a wake time that lands on a full cycle boundary. The tool works backward from a wake time or forward from a bedtime, adding a short wind-down. Shift work, children, and insomnia still override any clock trick—treat the output as a suggestion.
