DuPont shift calendar 2028
The DuPont work schedule is a 28 day rotation of 12 hour shifts that four crews run to cover the clock: 4 nights, 3 off, 3 days, 1 off, 3 nights, 3 off, 4 days, then 7 days off. It came out of DuPont's chemical plants in the 1950s and still runs in refineries, paper mills, and other continuous process plants.
People take it for the full week off at the end of every cycle, and put up with the rough middle: a single day off to flip from day shifts back to nights. This page shows the whole of 2028 on real dates for a crew whose cycle starts January 1.
Suits people who want a full week off every month and can absorb four nights in a row. The seven day break is the draw; the four night block and the single day off in the middle are the price.

DuPont 12h rotating, 2028
The grid shows a crew whose cycle starts January 1, 2028; other crews run the same rotation offset by a few days. The 28 day cycle divides evenly into weeks, so the rotation never drifts: whatever weekdays a crew works in January, it works in December. Crews on other phases can see very different weekends. To line the pattern up with your real start date, use the interactive shift pattern visualizer.

Put DuPont 2028 in your calendar
One file, every shift of the year, ready for Apple Calendar, Google Calendar, or Outlook. Shifts import with default times: day shifts 7am to 7pm, night shifts 7pm into the next morning (7am). Edit the times after import if your site runs different hours.
That file is the textbook rotation. Your real roster has swaps, overtime and cover shifts that no pattern predicts, so photograph it with Lumical and every shift lands in Apple Calendar. We make Lumical, so read this with that in mind.

A perfect rotation fits in a calendar file. A real roster does not.
Swaps, overtime, and holiday cover break the pattern. Reading a real roster is what the Lumical app does: photograph it and every shift lands in your calendar, overnights included. We make it, so weigh the recommendation accordingly.
Common questions
What is the DuPont shift schedule?
A 28 day cycle of 12 hour shifts: 4 nights, 3 off, 3 days, 1 off, 3 nights, 3 off, 4 days, and then 7 straight days off. Four crews stagger it by a week each, so the plant is always covered.
How many weekends off does DuPont give you?
Averaged across crews, 15.1 a year, but the range runs from 0 to 27. The 28 day cycle divides evenly into weeks, so each crew keeps the same weekdays all year: one crew's off blocks keep landing on weekends and another's never do. The January 1 crew in 2028 gets 13.
How long is the long break on DuPont?
Seven days, once per 28 day cycle, right after the four day shifts. It is the signature of the pattern and the reason crews defend it despite the quick flips between days and nights.
How many hours a year is DuPont?
2,208 hours in 2028: 184 shifts of 12 hours, averaging 42.3 a week. 50.5% of it is night work, 1,116 hours across 93 night shifts for the January 1 crew.
Does DuPont mix days and nights?
Yes, inside every cycle. The January 1 crew works 93 nights and 91 days in 2028, and spends 26 recovery days sleeping off the last night of a block.
How many days will you work on DuPont in 2028?
184 shifts, which comes to 2,208 hours at 12 hours each. That leaves 182 days off. The count moves by a shift or two depending on where your crew sits in the cycle on January 1.
How many crews does DuPont need to cover 24 hours a day?
4. The cycle runs 28 days with 14 of them worked, so keeping one position filled every day takes 2 crews, and a 12 hours shift needs 2 positions to fill the day.
How do I get this calendar into Apple Calendar?
Download the .ics file on this page and open it on your iPhone or Mac. Apple Calendar offers to add the whole year in one go. That covers the textbook rotation. A real roster has swaps, overtime and cover shifts, and for that we make Lumical: photograph the roster and every shift lands in Apple Calendar. We make it, so read that with the obvious bias in mind.
