4 On 4 Off Schedule Calendar 2026โ€“2027

By Sohail Manzoor ยท Updated

The 4 on, 4 off schedule is a 12-hour shift rotation: work 4 shifts in a row, then 4 days off, repeating every 8 days. Each crew works 4 of every 8 days, about 182.5 shifts and 2,190 hours a year, or an average of 42 hours a week. Also called: 4x4 schedule, 4 days on 4 days off.

Because the cycle is 8 days long, your days off move forward one weekday each week. Four crews (two on days, two on nights) cover 24/7 operation.

Four days off after every four shifts is easy to plan around, and no week ever has more than four shifts. Because the days off drift, though, you'll only get a full weekend off when the 8-day cycle happens to line up with one.

Hours and days off

Weekly hours and overtime on the 4 on, 4 off schedule

Crew A's hours aren't the same every week. Say its cycle starts on Monday, October 5, 2026 and the payroll week runs Sunday through Saturday. Then the 8 weeks before the pattern repeats come to 48, 48, 48, 36, 36, 36, 36 and 48 hours. Federal overtime is time and a half for anything past 40 in a payroll week, which works out to 32 hours of overtime per 8 weeks and about 208 in a year. Move the start of the payroll week, or start the crew on another weekday, and you'll get a different split.

Crew A gets 3 full weekends off (Saturday and Sunday both free) in those 8 weeks. Taking 2 shifts as vacation in the right spot gives 6 days in a row away from work.

The overtime calculator works out the pay for any single week.

4 on, 4 off schedule in Excel or Google Sheets

In Excel or Google Sheets, put crew A's first day in cell B1 and a column of dates from A2 down. This formula in B2, filled down, shows D for a working day or a dash for a day off:

=MID("DDDD----",MOD(A2-$B$1,8)+1,1)

The text in quotes is one character per day of the 8-day cycle. For crew B, which starts 4 days later, subtract 4 more inside the MOD, as in MOD(A2-$B$1-4,8). MOD gives a result from 0 up to 7 in both programs, even for dates before the start date.
