Crew A works 1 to 4 January 2027 and is off 5 to 8 January; Crew B is the mirror image. Because the cycle is 8 days, your work days move one weekday later each week, so full weekends off come and go rather than on a fixed rhythm. In 2027 Crew A has 19 full Saturday-and-Sunday weekends off and Crew B 20. On 12-hour shifts that averages 42 scheduled hours a week.
Crew A gets 184 shifts in 2027 and Crew B 181, a three-shift gap that comes from where the year ends in the cycle, not from the pattern. In 2028 it evens out differently.
Crew A and Crew B each have a one-page PDF and an .ics file. The rotating version has its own pair below its grid. Shift times are not in the files.
