Night Shift Sleep Window Calculator
Plan a sleep window around night shifts, commute time, and wind-down time so recovery is easier to protect.
What this calculator is for
The calculator uses shift end time, commute buffer, and sleep duration to suggest a sleep block and a wind-down start.
Night shift sleep works better when you do the math once and stop negotiating with it all week. A calculator keeps the schedule honest.

These calculators are for planning, not diagnosis or treatment.
Why the result is useful
Night shift recovery improves when the sleep block is built around the actual end of the shift instead of a normal daytime assumption.
Protect the wind-down, protect the sleep block, and keep the rest of the day light enough to repeat.
Recommended next step
Use the calculator result as a starting point, then pair it with a related guide or workflow so the number turns into a routine.

FAQ
Why does night shift need a separate calculator?
Because the usual bedtime math often does not match a shift that ends in the morning.
Should I sleep immediately after the shift?
Usually after a short buffer, enough to get home, settle down, and wind down.
What if my shift changes?
Re-run the calculator. Small schedule changes are exactly why a calculator helps.
