Police Shift Schedules Explained: 4-10s, 12-Hour Pitman, and How Rotating Days Off Work

Ask three officers what schedule they work and you can get three different answers — "four-and-two," "two-two-three," "five-eights on a rotating line" — and if you've never worked a patrol schedule, none of that says much about what a month actually looks like.

Here's the honest version up front: there's no single "police schedule." Departments build rotations around agency size, coverage needs, and the contract, so they land in one of a few shift-length families (8, 10, or 12 hours) with a rotation stacked on top. What follows is how the common ones are built. Your exact line, your hours before overtime, and how days rotate all come from your own department and CBA — so treat this as a map, not a rulebook.

The three shift-length families

Almost every patrol schedule starts with one decision: how long is a shift?

• 8-hour shifts — the traditional setup. More days worked, shorter individual shifts, three watches a day (days / evenings / nights). Often paired with a 5-on/2-off week.
• 10-hour shifts — four 10s a week is popular because it gives an extra day off while keeping overlap between watches for briefings and busy hours.
• 12-hour shifts — fewer days at work, longer days, and only two shifts needed to cover 24 hours (a day crew and a night crew). This is where the Pitman and similar rotations live.

None of these is automatically "better." They trade shift length against how many days you're commuting, and how your off days clump together.

4-on / 2-off

A six-day cycle: four days on, then two off, and the pattern repeats. Because six doesn't divide evenly into a seven-day week, your days off drift — this week they're Wednesday–Thursday, a couple weeks later they're on the weekend, then they roll again.

That drift is the whole trade. You will get some weekends, but on a schedule, not on the calendar everyone else uses. For a lot of officers the four-on stretch is short enough to stay recoverable, and the steady two-off keeps arriving without a long dry spell.

Pitman (2-2-3), with 12-hour shifts

If you work 12s, there's a good chance it's some version of the Pitman, also written 2-2-3. Over a two-week cycle a squad works: 2 on, 2 off, 3 on, 2 off, 2 on, 3 off. Four squads rotate through it so two crews cover days and two cover nights, keeping the clock filled.

Two things officers tend to like about it:

• You never work more than three days in a row.
• Every other week you get a three-day weekend — the same three days each fortnight, so it's predictable enough to plan around.

The catch is the 12-hour day itself, and — on many versions — rotating between day and night blocks, which is hard on sleep. (If you're fighting that rotation, our shift-work sleep guide walks through anchoring your sleep across the flip.)

4-10s: where the third day off comes from, and why it moves

Four 10-hour shifts is one of the most common patrol setups, and it's the one people search for most often without finding a straight answer. The appeal is simple arithmetic: 4 x 10 = 40 hours in four days instead of five, which buys a third day off every week.

The complication is that a four-day work block doesn't divide evenly into a seven-day week the way a five-day block does. Departments resolve that in one of two ways, and which one yours uses changes your life quite a bit:

• Fixed days off. Your off days are the same three every week — say Sunday, Monday, Tuesday. Predictable, easy to plan around, and usually allocated by seniority. Newer officers tend to get the off-day blocks nobody bid for.
• Rotating days off. Your off days shift forward through the week on a set cycle, so everyone eventually takes a turn with a weekend off and a turn with off days buried mid-week. Fairer over a year, harder to plan a standing commitment around.

A rotating 4-10 line often looks something like this, with the off block sliding forward each cycle:

The pattern above is illustrative, not universal — the length of the cycle, the direction it slides, and whether the watch (days/evenings/nights) rotates at the same time are all set by department policy and, in many agencies, by the collective bargaining agreement. Check your own shift bid document rather than assuming. Two agencies both calling their schedule "4-10s with rotating days off" can hand you very different years.

The thing worth internalising: on a rotating line, "my days off" is not a fact about the week, it's a fact about where you are in the cycle. Anything recurring in your life — a class, a standing appointment, a kid's Saturday fixture — has to be checked against the cycle, not against the calendar.

12-hour lines and rotating days off

Twelve-hour schedules solve the seven-day problem differently. Because 12s only need two crews to cover 24 hours, the common patterns build the rotation into the block itself rather than sliding it week to week. The Pitman 2-2-3 above is the clearest example: the pattern repeats on a 14-day cycle, which is divisible by seven, so your days off land on the same weekdays every fortnight and you get a full three-day weekend every other week without anything needing to slide.

That is the real trade between 10s and 12s on a rotating line. Ten-hour schedules give you a shorter day and a third day off, but the off days often move. Twelve-hour schedules give you a longer day and, on a 2-2-3 style line, off days that stay put. Which one is better depends entirely on whether your life needs shorter days or predictable ones.

5-8s and the rotating line

The classic 5-on / 2-off with 8-hour shifts is still around, often on a rotating line: you spend a set number of weeks on days, then rotate to evenings, then to nights (a "slow" rotation of several weeks), or you flip faster. Seniority usually decides who gets to hold a steady watch and who rides the rotation.

Rotating shifts are the hardest on your body clock, because "when I sleep" keeps changing. The upside is coverage fairness — the tough overnight watches get shared instead of dumped on the newest officers forever.

Where court days fit in

Here's the part civilian schedule guides always miss: your day off isn't always a day off. Subpoenas and court appearances land on the calendar independent of your rotation, so a scheduled off day can turn into a court day — sometimes with a wildly inconvenient start time right after a night shift. It's one of the reasons patrol officers get so protective of the off days they do control, and why "what does your week look like" is never a simple answer.

If you want to see your own rotation laid out on a calendar, the shift pattern calculator will do it — pick 4-10s or the 2-2-3, tell it one date you were on, and it prints the working days, the off days and how many full weekends the pattern actually gives you.

Common questions

What does "rotating days off" actually mean for police? It means your scheduled off days move through the week on a fixed cycle instead of staying on the same weekdays. The purpose is fairness: over a full cycle, everyone gets a share of weekend off blocks rather than seniority holding them permanently.

Do 10-hour police shifts always have rotating days off? No. Some agencies run 4-10s with fixed off days assigned by seniority bid, others rotate them. The shift length and the off-day policy are separate decisions, and both are usually written into the shift bid or the bargaining agreement.

Why do 12-hour schedules keep days off in the same place when 10-hour ones don't? Because the common 12-hour patterns repeat on a 14-day cycle, and 14 divides evenly by seven. A four-day work block doesn't, so a 10-hour line either has to fix the off days or let them slide.

How far ahead can I know my days off? On any fixed repeating pattern, indefinitely — the cycle is arithmetic, so once you know your pattern and where you are in it, the dates are determined. What you can't predict are the things layered on top: court subpoenas, overtime holdovers, callbacks, and training days.

The honest summary

The "best" schedule is really about the life you want around the job — long breaks you can travel on, or a steadier week you can build a routine on. What matters is knowing which one you're actually on, and being able to see your real days months ahead instead of decoding a rotation chart every time someone asks if you're free.

That last part is exactly what a shift calendar is for: set your rotation pattern once, and let the months build themselves — court days and all.

General information, not legal or workforce advice. Your department's policy, general orders, and collective bargaining agreement set your actual rotation, hours before overtime, and how court time is paid.
