How the 4 on 4 off pattern works
On a 4 on 4 off rota you work four shifts in a row, then have four days off. The cycle is 8 days long, so it does not line up with the 7-day week: your days off move one day later each week, which is why your weekends off change from month to month.
This page shows the day-shift version with two crews (A and B), four days apart, so one crew is always on. If your site rotates days and nights, use the 4 on 4 off days and nights page.
Cycle for crew A: DDDDOOOO (D = day, N = night, F = 24-hour shift, O = off).
