Shift Worker Sleep Planner

Which of three schedule templates you get is decided first, and for the Rotating option that decision is made by your shift start hour rather than by the dropdown: a rotating worker starting before noon is planned exactly like a day worker, one starting between noon and eight in the evening like an evening worker, and one starting later like a night worker. Day-shift plans run backwards from the alarm, opening the sleep window at your start hour minus your target sleep minus a one-hour buffer for getting ready, and closing it an hour before you clock on. Evening and night plans run forwards from the end of your shift instead, opening an hour after you finish and closing once your target hours have elapsed, which is why the default ten-at-night to six-in-the- morning shift produces a seven in the morning to half past two window. The nap suggestion follows the same split: night workers are pointed at a ninety-minute nap three hours before clocking on, evening workers two hours before, and day workers are told they should not need one.

Anchor sleep for days off is simply half your target, rounded to the nearest hour. Two fields are worth calling out honestly — consecutive days on and days off are collected but never enter any calculation, so changing them will not move a single output. The difficulty rating likewise keys off the dropdown alone, meaning a rotating worker is always warned as Very High even while being handed an ordinary day-shift plan.
