2-2-3 Shift Calculator

Living life on a 2-2-3 rota

The first thing that strikes you about the 2-2-3 is how quickly your week stops being a thing you have to remember. You work two days, you get two off, you work three, and then the second half of the fortnight runs the same shape in reverse. After a cycle or two it just lives in your head — you stop reaching for the rota on the fridge because you already know that next week is this week turned inside out.

That rhythm is the whole appeal. Because the same fourteen days repeat, your days off land on a pattern you can actually plan around weeks, even months, ahead. If you know you've got that long three-day rest coming at the end of the cycle, you can book a weekend away, sort a dentist appointment, or commit to a Saturday five-a-side without first untangling a spreadsheet. People coming off irregular or "as needed" rotas often describe the move to a 2-2-3 as getting their diary back.

It does take a fortnight or two to settle into. The early part of the cycle feels generous — two on, two off is a gentle in-and-out where you're never more than a couple of shifts from a rest day. Then the three-on block arrives and that's where the week earns its name, particularly when those three are nights. The trick most people land on is treating the cycle as two halves: an easy run, then a heavier run with a proper stretch of rest waiting at the end.

One quiet upside that doesn't get mentioned enough: your shifts fall on different weekdays from one fortnight to the next, so you're not always the person stuck working every Friday or always missing the Monday football. Over a few cycles the pattern spreads itself across the week, which feels fairer than a fixed rota that pins your day off to the same dead weekday forever.

Why people end up on the 2-2-3

The 2-2-3 turns up wherever a workplace has to be staffed around the clock and can't simply close at six. Think control rooms, ICU and A&E wards, custody suites, security desks, refineries and continuous-process plants, and dispatch centres. Anywhere the lights never go off and the desk can never sit empty is a candidate for this kind of rota.

The reason it works for those places is the maths of four teams. Run four crews against this pattern, offset from each other, and at any given moment you've got one team on days, one on nights, and the other two resting — so the building is always covered without anyone being asked to live at work. You'll often see the teams labelled A, B, C and D, or by colour, but the structure underneath is the same on every team: the 2-2-3 shape, just started on a different day.

The naming trips a lot of people up. You'll hear it called the Pitman schedule, the Panama schedule, or sometimes a "slow rotation" — and they're all the same thing. Pitman is the older name that's stuck around in plenty of UK workplaces; Panama caught on more widely in the US. Don't get hung up on which one your employer uses; the underlying rota is identical.

The other defining feature is the day/night alternation. On most 2-2-3 setups your team doesn't sit on days forever — you swing between day shifts (often something like 07:00–19:00) and night shifts (often 19:00–07:00) as the fortnight turns over. That swing is what keeps the rota fair across the whole crew, so nobody's permanently lumbered with the small hours, but it's also the part that takes the most getting used to.

The good weeks and the hard weeks

Let's be honest about both sides, because the 2-2-3 is genuinely one of the better continuous rotas to be on — but it isn't free of grind.

On the good side, predictability is king. Your days off repeat on a fixed shape, which makes the 2-2-3 a favourite with parents juggling childcare, anyone holding down a second job or a side hustle, and people who like to actually commit to things — a course, a gym routine, a regular hobby — without renegotiating every week. The repeating fortnight also makes swaps easier to think about, because you and a colleague can both see exactly where your rest days sit. And those two-day rests sprinkled through the cycle mean you're rarely more than a couple of shifts from a breather, which keeps the whole thing feeling sustainable.

The hard weeks are real too. The three-on block at the back of the cycle is where fatigue stacks up, and if it falls on nights it can be a slog — your sleep is upside down and the third shift is always the one you feel in your bones. The day-to-night swing asks a lot of your body clock, and not everyone adapts to it easily; blackout curtains and a strict wind-down routine stop being nice-to-haves and start being survival kit. And while the long three-day rest at the end of the cycle is lovely, plenty of people find the shorter two-day breaks vanish faster than they'd like — one day to recover, one day to actually live, and you're back in.

None of that is a dealbreaker for most people, but it's worth going in with eyes open. The 2-2-3 rewards you with a planner-friendly life in exchange for some heavy stretches; whether that's a good trade depends a lot on how well you handle nights.

Pulling your own 2-2-3 calendar together

The calculator on this page turns the pattern into an actual dated year for you. It's quick:

1. Pick the 2-2-3 (Pitman / Panama) card — it's already selected on this page, so you can usually leave it as-is.
2. Choose your team — A, B, C or D. This is the one thing worth getting right, because each team runs the same pattern offset from the others, so the wrong choice shows you somebody else's days. If you're not sure which you're on, see the last question below.
3. Enter your cycle start date — the first day of your current or most recent fortnight. This anchors everything, so if you're unsure, check with your shift manager or your rota system for the start of the current block.
4. Generate the 12-month view — the full year fills in, with day shifts, night shifts and rest days laid out so you can see your weekends and runs of rest at a glance. Bank holidays are flagged for you.

Two things worth using once it's built: the date checker in the sidebar lets you punch in any single date — Christmas, a birthday, a friend's wedding — and tells you instantly whether you're on or off. And the export button drops the whole calendar into Google Calendar or a downloadable file, so your shifts sit alongside the rest of your life on your phone.
