Rotating Shift Schedules Compared
Last updated June 15, 2026
The common rotating shift schedules differ mainly in three things: shift length (8, 10, or 12 hours), cycle length (how many days before the pattern repeats), and how the work days are clustered. Most 12-hour rotations average about 42 hours a week; an 8-hour, three-team rotation can hold a true 40. The table below compares the six best-known patterns side by side, and each links to a generator that builds a printable calendar.
Side-by-side comparison
| Schedule | Cycle | Shift | Work / off days | Avg hrs/week | Rotation |
|---|---|---|---|---|---|
| 4 on 4 off | 8 days | 12 hr | 4 / 4 | 42 | Days only |
| 4 on 3 off | 7 days | 10 hr | 4 / 3 | 40 | Days only |
| Pitman (2-2-3) | 14 days | 12 hr | 7 / 7 | 42 | Day / night by team |
| Panama | 28 days | 12 hr | 14 / 14 | 42 | Slow day → night |
| DuPont | 28 days | 12 hr | 14 / 14 | 42 | Day ↔ night |
| Southern Swing | 28 days | 8 hr | 21 / 7 | 42 | Day → swing → night |
The work/off and hour figures are counted directly from each rotation's fixed cycle, so they are exact. The "best for" verdicts below are judgment calls — the right pattern still depends on your operation's coverage needs and what your team values most.
- Shift length is the first choice: 12-hour rotations need two teams; 8-hour need three.
- Most 12-hour rotations average ~42 hours a week; only 8-hour (or 10-hour 4-on-3-off) hold a true 40.
- DuPont gives the longest single break (7 days off); 4-on-4-off gives the most frequent long breaks.
- Pitman and Panama both use the 2-2-3 rhythm with every other weekend off.
- Cycle lengths range from 7 days (4-on-3-off) to 28 days (DuPont, Panama, Southern Swing).
Which rotating shift schedule is best?
There is no single best rotating shift schedule, but there is a best one for each goal. For 24/7 coverage with every other weekend fully off, Pitman (2-2-3) is the most popular. For a long recovery break, DuPont builds in a full week off each cycle. For the simplest, most predictable rhythm, 4-on-4-off wins. For a true 40-hour week, choose 8-hour Southern Swing or 10-hour 4-on-3-off.
- 4 on 4 off — best for simple, predictable 24/7 coverage with frequent long breaks.
- 4 on 3 off — best for a flat 40-hour week with a three-day weekend feel and no built-in overtime.
- Pitman (2-2-3) — best for never working more than three days running and getting every other weekend off.
- Panama — best for the 2-2-3 rhythm while still rotating through night shifts.
- DuPont — best for a full seven-day break packed into every cycle.
- Southern Swing — best for shorter 8-hour shifts that rotate through day, evening, and night.
Pitman, Panama, 2-2-3, 2-3-2: which name means what?
These names cause real confusion because sources disagree. Here is how they actually relate:
- 2-2-3 is the pattern itself — 2 days on, 2 off, 3 on, then 2 on, 2 off, 3 off across 14 days. "2-3-2" is the same rhythm described from a different starting day.
- Pitman is the common name for a 2-2-3 schedule run on a 14-day cycle, usually on a fixed shift time, where teams alternate days and nights.
- Panama is a 2-2-3 stretched over 28 days that adds a slow rotation from a fortnight of day shifts to a fortnight of nights.
So yes — Pitman is a 2-2-3 schedule, and Panama is a 28-day, day-to-night variant of the same 2-2-3 rhythm. If a source calls Pitman "2-3-2," it is describing the identical pattern from a different day-one.
How to read "average hours per week"
A rotating schedule almost never gives a tidy 40-hour calendar week, so the fair way to compare patterns is the cycle average: total worked hours in one full cycle, spread evenly across its days, scaled to seven. A 4-on-4-off rotation on 12-hour shifts works four 12-hour days every eight days — 48 hours per eight days, which averages 42 hours a week even though no individual week is ever exactly 42. That two-hour-a-week overage above 40 is why most 12-hour rotations build in regular overtime; the overtime pay calculator shows what that is worth, and the federal overtime basics guide explains why overtime is still judged one workweek at a time, not by the cycle average.
8, 10, or 12-hour shifts: the core trade-off
Shift length is the first decision, and it cascades into everything else. Twelve-hour shifts cover a 24-hour day with just two teams and tend to produce more whole days off, which is why 4-on-4-off, Pitman, Panama, and DuPont are all built on them — the trade is longer, more tiring days and a week that runs a couple of hours past 40. Eight-hour shifts, like the Southern Swing, need three teams to cover the day and give shorter, less fatiguing shifts, at the cost of more workdays and fewer long breaks. Ten-hour shifts, as in 4-on-3-off, sit between the two and can land a clean 40-hour week.
Fixed vs. rotating shifts
A "fixed" rotation keeps you on the same time of day — our 4-on-4-off and 4-on-3-off generators show a steady day-shift crew. A "rotating" pattern moves you through different shift times: DuPont swaps between day and night within each cycle, Panama drifts slowly from a fortnight of days to a fortnight of nights, and the Southern Swing walks through day, then swing (evening), then night. Faster rotation spreads the unpopular night hours evenly but is harder on the body clock; slower rotation is gentler to adjust to but keeps you on nights for longer stretches.
The six patterns at a glance
- 4 on 4 off — the simplest 12-hour rotation: four straight days on, four straight off, on an 8-day cycle. Predictable, with long recovery blocks; best for round-the-clock cover without rotating nights in the basic form.
- 4 on 3 off — four 10-hour days then three off, a 7-day cycle that lands a true 40-hour week with a built-in three-day weekend feel and no automatic overtime.
- Pitman (2-2-3) — the public-safety favourite: a 14-day cycle of 2 on, 2 off, 3 on, 2 off, 2 on, 3 off, so every other weekend is fully off and you never work more than three days in a row.
- Panama — the same 2-2-3 rhythm, but stretched over 28 days with a slow rotation from two weeks of days into two weeks of nights.
- DuPont — a 28-day classic of heavy industry that packs a full seven consecutive days off into every cycle, rotating between day and night shifts the rest of the time.
- Southern Swing — the 8-hour, three-team option: a week of days, a week of swings, a week of nights across a 28-day cycle, for operations that prefer shorter shifts and a full rotation through every slot.
Frequently asked questions
Which rotating shift schedule has the most days off?
It depends on how you count. The DuPont schedule gives the longest single block — a full seven days off every 28-day cycle. 4-on-4-off gives the most frequent long breaks (four off after every four on). The 8-hour Southern Swing has the most workdays because shorter shifts need more of them to cover the same hours.
Why do most 12-hour rotations average 42 hours a week, not 40?
Because two 12-hour teams covering a 24-hour day work out to 42 hours each per week on average (84 combined ÷ 2). The clean way to hit 40 is either 8-hour shifts with three teams or a 10-hour pattern like 4-on-3-off. The extra two hours on a 12-hour rotation normally land as overtime.
What's the difference between Pitman and Panama?
Both use the 2-2-3 rhythm (you never work more than three days running and get every other weekend off). Pitman runs on a 14-day cycle on a fixed time of day; Panama doubles it to 28 days and adds a slow rotation from day shifts to night shifts halfway through.
What's the difference between Pitman and DuPont?
Pitman is a 14-day 2-2-3 cycle where you never work more than three days in a row and get every other weekend off. DuPont is a 28-day cycle that front-loads longer runs of work in exchange for a full seven consecutive days off each cycle. Both use 12-hour shifts and average about 42 hours a week, but DuPont trades Pitman's steady rhythm for one long break.
Is the Pitman schedule the same as 2-2-3?
Yes. "Pitman" is the common name for a 2-2-3 schedule run on a 14-day cycle (2 on, 2 off, 3 on, 2 off, 2 on, 3 off). Some sources call the same rhythm "2-3-2" because they start counting on a different day — it is the identical pattern.
Can I build my own pattern instead?
Yes — the shift schedule generator accepts any "N days on, M days off" pattern and prints a calendar from your start date.
