How this Standard DuPont Shift Schedule: 28-Day Rotation works
Standard DuPont is a 28-day rotation: four nights, three off, three days, one off, three nights, three off, four days and seven off.
The full 28-day repeating cycle
14 working shifts and 14 rest days per 28-day cycle. Hours depend on the shift length set by your employer. This is an individual employee's repeating sequence, not a guarantee of full-team 24/7 coverage.
This is the standard 28-day DuPont sequence confirmed by TimeTrex, not the modified 30-day version.

Standard DuPont: work blocks and recovery
The standard DuPont roster is a four-crew, 28-day rotation commonly illustrated with 12-hour shifts. A worker completes 4 nights, 3 off, 3 days, 1 off, 3 nights, 3 off, 4 days and 7 off. This gives 14 working shifts and 14 days off over the cycle, averaging 42 hours per seven days when shifts last 12 hours. The demanding cluster of working days can create fatigue: individual employers must assess rest, hours and legal requirements. The 30-day modified 4-2-3-3-3-4-4-7 example has a different order and length.
