28-DAY ROTATION

DuPont Shift Schedule Generator

Generate a DuPont rotating calendar with 12-hour work blocks and the repeating long break.

THE PROBLEM THIS SOLVES

The DuPont cycle contains several work and rest blocks, making long-range planning difficult without a calendar.

Start with a verified first workday and generate one to twelve months. Check the result against your team roster before relying on it.

Showing the first 42 days. Your downloaded calendar contains all 91 days.

Verify the generated calendar against several dates on your official roster before importing it.

HOW THE PATTERN WORKS

A calendar needs the right starting point.

The commonly used DuPont pattern spans 28 days and includes changing work blocks and a seven-day break. Employer variations and team offsets are common.

VERIFY BEFORE IMPORTING

Four checks that prevent a wrong calendar.

  • Verify your employer’s exact sequence
  • Confirm the crew position
  • Record day and night blocks
  • Check the seven-day break against the roster
COMMON QUESTIONS

What the generator can and cannot do

Is every DuPont schedule identical?

No. Employers may change the sequence or rotation timing.

Why is my generated crew one day off?

The anchor may not be the first workday of your crew’s cycle.

Does the seven-day break always remain free?

Training, overtime, swaps and employer needs can change actual assignments.
