Preview a repeating 4-on-4-off shift pattern, understand the average hours it creates, and then turn the pattern into a real roster with your actual staff, availability and work rules.
A 4-on-4-off schedule repeats every eight days: four consecutive work days followed by four consecutive days off. With 12-hour shifts, it averages 42 working hours per week across the full cycle.
Choose the first work day of the cycle. This previews the repeating calendar pattern. Then add your actual staff below to create a schedule around availability, qualifications and rest rules.
Add your team, qualifications, availability and work rules to generate a 7-day schedule. No account required.
The cycle is simple: work four days, take four days off, and repeat. Because the cycle is eight days rather than seven, work days move through the calendar week over time.
A date generator can show which crew is theoretically on duty. It does not know whether a specific employee is on leave, has the required licence, is available for nights or would breach a rest or weekly-hour rule.
Use the pattern as the coverage structure, then assign real workers against the constraints that matter to your operation.
The pattern is common in operations that need predictable 24/7 coverage and can support 12-hour watches. It gives employees blocks of four days off, but the suitability of consecutive long shifts depends on the work, fatigue controls and rules that apply to the organisation.
Scheduling patterns and staffing formulas are planning aids. Whether the schedule works depends on the workers, roles, qualifications, availability, leave, rest rules and other requirements that apply to your organisation.
Four 12-hour shifts equals 48 hours every eight-day cycle. Across the repeating cycle, that averages 42 hours per seven-day week.
A common continuous day/night design uses multiple crews offset through the cycle, but the required workforce depends on how many positions must be covered simultaneously and the work rules that apply.
The pattern preview only generates work and off dates. Rosterzen can then assign actual workers around availability, qualifications, hours and rest rules.
