Each band names the working crew and shift type. The other crew is off. Blank dates are before the start date.

How to use your calendar
- Choose a reference crew, then enter the first date of its opening work block. Crew A remains the default for older saved settings and links.
- On a phone or tablet, select Edit settings to open the form.
- Enter the reference crew's first work day. Choose the first day of a four-day work block.
- Pick the year to show, then choose Crew A only or crews A and B. Crew B works when Crew A is off.
- Choose day or night shifts and a colour for each crew. Changing the shift type keeps the same work dates.
- Save on this device, share a link, print the year or download a calendar file for each crew.
How it works
- D D D DDay shift · 4 days
- O O O OOff · 4 days
The pattern repeats every eight calendar days: four work days, then four days off. The example above uses day shifts. For night shifts, the four work dates use N instead of D. D means a day shift, N means a night shift and O means off.
The reference crew uses your starting date with no offset. The other crew is four days apart, so its work dates fall on the reference crew's days off. Both crews stay blank before your chosen start date.
For each date, the pattern position is (date minus start date minus crew offset) modulo eight. A negative remainder wraps into the cycle. Counting whole calendar days keeps the rotation consistent across leap days and clock changes.
Work day counts cover the year you choose. They exclude days off and blank dates before the start. The calendar does not adjust for leave, overtime or shift swaps.
Calendar files contain one event for each block of consecutive work days, using whole dates. A night shift is labelled Night shift; its actual start and finish times are not set by this tool. Confirm those times against your employer's rota.
Worked example
Crew A starts on Sunday, 3 January 2027, with both crews shown:
- Monday, 1 March 2027: Crew A works, on day 2 of its four work days. Crew B is off.
- Saturday, 25 December 2027: Crew A is off and Crew B works.
- Crew A has 183 work days in 2027. Crew B has 180. The first two days of January are blank.
Common questions
How many days a year do you work on 4 on 4 off?
You work half the days in each complete eight-day cycle. The exact count in a calendar year depends on the cycle position, leap years and any blank dates before your start date. Use the work day count for your settings.
How many hours a week is 4 on 4 off with 12-hour shifts?
Four 12-hour shifts total 48 hours over eight days, averaging 42 hours a week before unpaid breaks. Individual calendar weeks can differ. With a 30-minute unpaid break per shift, the average is 40.25 paid hours a week.
Does 4 on 4 off include weekends?
Yes. The eight-day cycle continues through weekends. Because it is longer than a seven-day week, the work block starts on a different weekday each time.
How do two crews cover every day?
Crew B uses a four-day offset. When Crew A works, Crew B is off, and when Crew A is off, Crew B works. From the start date, one crew works each date. This does not establish coverage for both day and night shifts.
Can I use this for night shifts?
Yes. Choose Night shifts to show N instead of D on the same work dates. Calendar downloads use whole dates and a Night shift label. Check the actual shift times with your employer.
