Practical guide
How the DuPont Schedule Generator works.
The DuPont schedule is a four crew rotation built around 12 hour day and night shifts across a 28 day cycle. Its recognizable sequence includes four night shifts, three days off, three day shifts, one day off, three night shifts, three days off, four day shifts, and seven days off.
The long rest block is attractive, but weekly hours, consecutive shifts, day to night transitions, fatigue, and overtime exposure still require review. The generator shows both one crew calendar and the complete four crew phase relationship.
Rotation length
A complete DuPont cycle covers 28 calendar days.
Crew coverage
Four phase offsets maintain one day crew and one night crew in the standard pattern.
Scheduled hours
The common pattern includes fourteen 12 hour shifts, or 168 scheduled hours per cycle.
Worked example
If Crew A begins with four night shifts, the other crews begin at different points in the same 28 day sequence. The matrix makes those offsets visible on real dates.
Check before use
- Confirm local fatigue and rest requirements.
- Review weekly overtime instead of relying on the cycle average.
- Plan relief for leave, training, and vacancies.
Why this tool exists
Make the dupont rotation calendar easier to review.
Generate the full 28 day sequence with crew offsets, day shifts, night shifts, and the extended rest period.
Use a real operating input
Generate the full 28 day sequence with crew offsets, day shifts, night shifts, and the extended rest period.
See the decision clearly
Inspect weekly hour swings, quick returns, night transitions, and the coverage created by all four crews.
Keep the boundary visible
DuPont schedules have local variants. Confirm the exact sequence, fatigue controls, agreements, and pay treatment before publishing.

Common questions
What sequence does this DuPont generator use?
The default is four nights, three days off, three days, one day off, three nights, three days off, four days, and seven days off over 28 days.
Can I use this result as a final payroll or staffing record?
Use the result as a planning aid. Confirm policies, workweek boundaries, pay rules, staffing requirements, and final records with the people responsible for them.
How many crews does a DuPont schedule use?
The common continuous coverage design uses four crews with coordinated phase offsets across day shifts, night shifts, and rest periods.
How is DuPont different from a Panama schedule?
DuPont uses a 28 day sequence with a seven day rest block. A common Panama schedule follows a repeating 2 2 3 cadence across a shorter cycle.
