How to read this calendar

A night shift is counted on the date it begins, even though it ends the next morning; a rest date after a night shift is not necessarily a full 24 hours free. Fixed Monday–Friday schedules assume weekends off and do not include holidays automatically. Exceptions apply only to the selected date; they do not change the rotation. Check all dates against the employer's official schedule.
