By Sohail Manzoor · Updated

Pick your rotation to see how it works, the hours it adds up to, and a calendar set to your crew's start date that you can add to your phone. Not listed? Type any pattern into the custom shift schedule generator. (A 2-2-3 schedule is the Pitman pattern; with crews swapping days and nights it is the Panama schedule.)
