## **Shift Work Calendar FAQ**
### **What is a shift work calendar?**
A calendar with your crew's working days, nights and days off marked on every date, worked out from your rotation. It lets you see at a glance which weekends, holidays and birthdays you have off.
### **Which 12-hour shift schedule has the most weekends off?**
Of the four rotations here, for crew A in 2027: 2-2-3 26, DuPont 26, Pitman 26, 4-on-4-off 21 full weekends (Saturday and Sunday both off). Other crews can differ by a weekend or two.
### **Do all of these schedules average the same hours?**
Yes. All four use 12-hour shifts with four crews, so each crew works half the days and averages 42 hours a week. They differ in how the days are grouped and whether crews rotate between days and nights.
