4 on 2 off shift calendar 2026
The 4 on 2 off pattern is a 6 day cycle: four 8 hour shifts, two days off, repeat. A third of the days are free. It is a factory rotation above all, common in semiconductor and automotive plants; in Japan it is searched as 4勤2休 and in Korea as 4조2교대, where three offset crews keep a line running every day.
This page lays out the whole of 2026 for a crew whose first block starts January 1: every shift, every off pair, and the weekends that survive. There is a days grid, stats for the days and nights variants, and a calendar file you can import in one tap.
4 on 2 off, days, 2026
The grid shows a crew whose cycle starts January 1, 2026; other crews run the same rotation offset by a few days. The 6 day cycle does not divide evenly into weeks, so the rotation drifts through the weekdays. Other crews get a similar year, just shifted. To line the pattern up with your real start date, use the interactive shift pattern visualizer.

A perfect rotation fits in a calendar file. A real roster does not.
Swaps, overtime, and holiday cover break the pattern. Reading a real roster is what the Lumical app does: photograph it and every shift lands in your calendar, overnights included. We make it, so weigh the recommendation accordingly.
Common questions
How does the 4 on 2 off schedule work?
Four 8 hour shifts in a row, then two days off. The cycle is 6 days, one short of the week, so each block starts one weekday earlier than the last and the whole pattern realigns with the calendar every 42 days.
How many days off does 4 on 2 off give per year?
A third of the year: 121 days off on paper in 2026. Compare 4 on 4 off or 3 on 3 off, which rest half of all days. The trade is shift length: this pattern usually runs 8 hour shifts, so the average week is 37.4 hours.
How many full weekends off does 4 on 2 off give?
The off pair covers Saturday and Sunday only when it lands exactly on them, which the 42 day drift makes happen about once in six weeks. In 2026 a crew starting January 1 gets 9 full weekends on days, and crews average 8.7. Nights average 0, because a Friday night shift runs into Saturday morning.
How many hours a year is 4 on 2 off?
1,952 hours in 2026: 244 shifts of 8 hours, averaging 37.4 a week. With 12 hour shifts the same cycle averages 56 hours a week, which is why the 12 hour version is rare.
Why does 4 on 2 off feel harder than the numbers suggest?
The breaks are never longer than two days, and on nights the first of the two is a recovery day: the nights variant has 61 of them in 2026, cutting its usable days off to 60. Short blocks of rest, drifting weekdays, and no long block to reset on.
