4 On 4 Off Schedule Generator
A 4-on/4-off cycle gives equal blocks of working and off days. Shift length and day/night rotation determine the actual weekly-hour average used by your operation.
Enter your scheduling assumptions
Change the inputs and the result updates immediately. Keep the assumptions realistic—the output is only as useful as the staffing model you give it.
4 work/duty days in each 8-day cycle
This calendar shows the stated repeating pattern. Team phase offsets, day/night handoffs, local policy, labor rules, and qualification requirements still need to be applied for an operational schedule.
Method
The generator repeats four working days followed by four off days. The preview uses a 12-hour shift assumption only for the average-hours estimate.
Example
The eight-day cycle is 50% working time. At 12 hours per workday it averages 42 scheduled hours per seven calendar days.
What the answer means
Treat the calendar as the repeating skeleton for one team. Multi-team operations still need crew offsets, day/night assignments, handoffs, qualifications, and coverage validation.
What this tool does not prove
Day/night rotation, handoff timing, and whether the 12-hour assumption fits your operation are separate decisions.
Answer the planning question before assigning names

Preview the repeating cycle across a multi-week calendar.
Choose a start date so the pattern maps to real dates.
Use the staffing calculators to confirm the rotation can support your required daily coverage.
Capacity math cannot see every person-level scheduling constraint
A staffing model can be mathematically feasible and still fail when only certain people are qualified for a role, approved absences remove key people, assignments overlap, rest windows are too short, or coverage changes on specific dates. Those are the checks RoleSchedule keeps attached to the schedule itself.
