Night Shift Planner - Custom Sleep Calculator

What does your shift look like?

We tailor calculations based on how consistently you work nights.

Permanent Night Shift Consistent graveyard hours every single week.

Rotating Shifts Flips between days, evenings, and nights.

Your body finds it easier to push bedtime later than earlier — so rotation direction changes how hard adaptation will be.

Forward (Clockwise) Day → Evening → Night. The easier direction to adapt to.

Backward (Counterclockwise) Night → Evening → Day. Harder on the body — we'll add extra guidance.

Not Sure / Irregular No consistent pattern, or unsure of the official term.

We use both ends of your shift to time light exposure, plus your wind-down window after work.
