Find my crew

How the crew finder works

A rotation repeats on a fixed cycle: 28 days for DuPont, 14 for 2-2-3, 6 for 48/96. Every crew works the same cycle, started on a different day. So a few remembered days pin down two things: which rotation you are on, and where you are in its cycle. The finder tries every rotation of the shift schedule generator, the day crew and the night crew of fixed patterns, and every possible start day, and keeps the ones that match every date you enter.

Which dates to enter

• Three or four dates usually leave one answer. If more than one schedule fits, the finder names a date that tells them apart: look that date up on your roster and add it.
• Mix work days and days off. A day off rules out as many schedules as a shift does.
• Spread them out over two or three weeks rather than picking days in a row.
• Not sure whether it was a day or a night? Choose Any shift.
• Already know your rotation? Pick it under Rotation to look only at its crews.

Crew letters

Crew letters (A, B, C, D, or platoons on firefighter rotations) are names an employer gives, and they follow no single standard: your A shift may start the cycle on a different day from the A in our calendars. So the finder doesn’t guess a letter. It gives the day your crew’s cycle started, which is all a shift calendar needs, and its link opens that calendar already set to your crew. Your posted rotation calendar or supervisor can confirm the letter.

When nothing fits

• Traded, covered or overtime shifts aren’t part of your rotation: leave those days out.
• Kelly days aren’t tried. Enter days you worked and regular days off only.
• A mistyped date: with three or more dates and no match, the finder lists the schedules that fit all but one date, and names that date.
• A rotation that isn’t listed: choose My own cycle and type it, one letter per day (D day, N night, E evening, X 24-hour, - off). Every start day is tried.
