How it works
Rotating schedules repeat on a fixed cycle. A DuPont crew, for example, repeats every 28 days. Once you tell the calendar one date you know, it lines the cycle up with the real calendar and works out every shift, years forward and back. US federal holidays are calculated for every year automatically.
Night shifts
A shift belongs to the day it starts. "Monday night" starts Monday evening and ends Tuesday morning, so it shows on Monday. A night shift that ends on a holiday morning is listed separately from holidays you actually work.
