Each crew rotates through days and nights. The 7 days off in a row every four weeks is the schedule's best-known feature. Crews start one week apart, so on any day one crew works days, one works nights and two are off.
In return for that long break, crews work a block of four nights, and they get only one day off between the three day shifts and the next three nights.

Weekly hours and overtime on the DuPont schedule
Crew A's hours aren't the same every week. Say its cycle starts on Monday, October 5, 2026 and the payroll week runs Sunday through Saturday. Then the 4 weeks before the pattern repeats come to 48, 60, 48 and 12 hours. Federal overtime is time and a half for anything past 40 in a payroll week, which works out to 36 hours of overtime per 4 weeks and about 468 in a year. Move the start of the payroll week, or start the crew on another weekday, and you'll get a different split.
Crew A gets 2 full weekends off (Saturday and Sunday both free) in those 4 weeks. Taking 2 shifts as vacation in the right spot gives 9 days in a row away from work.
The overtime calculator works out the pay for any single week.
DuPont schedule in Excel or Google Sheets
In Excel or Google Sheets, put crew A's first day in cell B1 and a column of dates from A2 down. This formula in B2, filled down, shows the shift letter (D day, N night) or a dash for a day off:
=MID("NNNN---DDD-NNN---DDDD-------",MOD(A2-$B$1,28)+1,1)
The text in quotes is one character per day of the 28-day cycle. For crew B, which starts 7 days later, subtract 7 more inside the MOD, as in MOD(A2-$B$1-7,28). MOD gives a result from 0 up to 27 in both programs, even for dates before the start date.
DuPont schedule questions
How does the DuPont schedule work?
Every crew runs the same 28-day cycle (4 nights, 3 off, 3 days, 1 off, 3 nights, 3 off, 4 days, then 7 days off, repeating every 28 days). The crews start it on different days, and that's how the site stays covered.
How many hours a week is the DuPont schedule?
It averages 42 hours a week, since each crew works 14 shifts of 12 hours in every 28 days. Single weeks can come out higher or lower than the average.
How many days a year do you work on a DuPont schedule?
About 182.5 shifts, which comes to 2,190 hours over a year.
What is the difference between the Pitman, Panama and DuPont schedules?
All three use four crews on 12-hour shifts. Pitman is the 2-2-3 pattern over 14 days with each crew on fixed days or nights; Panama is the same 2-2-3 pattern with crews swapping between days and nights; DuPont is a 28-day cycle that mixes day and night blocks and ends with 7 days off in a row.
