Which rotation am I on?
Most officers can tell you they work four on, four off — but not what it is called. Tap out four weeks of your roster and this will tell you.
Tap the days you work
Start anywhere in your cycle — it does not matter which day you begin on. Tap once for a day you work, twice for a day off, three times to clear it. Six days starts narrowing it down; two weeks is usually enough to be certain.

The shift calendar built for your rotation, off-duty work, and life on and off the clock.
Once you know what it is called, you can save it once and stop counting — the calendar fills itself in from there.
Every rotation, drawn out
Find the shape that matches your roster. Amber is a day shift, indigo a night, teal a twenty-four hour tour, and pale is a day off.

What it will be called on your paperwork
Canadian services rarely name a rotation the way this page does. What you will find in the collective agreement is an article headed Compressed Work Week, or Shift Schedules, setting out the shift length and the rest between shifts rather than a chart with a name on it.
So the quickest way to identify your own is to work from two numbers: the length of a shift, and the minimum hours off between them. A ten-hour compressed work week clause typically guarantees at least fourteen consecutive hours off duty. Fire suppression in Ontario averages 42 hours a week. Hospital nurses work 7.5 and 11.25-hour tours. Each of those is written down somewhere you can check, and each fixes the shape of the cycle.
Checked 7 August 2026. Quoted from the collective agreements, statutes and regulators named above. Agreements are renegotiated and employment standards are amended — confirm the current text before relying on a figure or a threshold.
If nothing matches
Plenty of agencies run a variation — an extra day bolted on, a relief line that breaks the cycle, a local arrangement with no name at all. If none of these fit, the rotation is still yours to keep: you enter the days once in the app and it repeats them for you, named or not.
Why two rotations can look identical
Panama and Pitman are the same on-off pattern — two on, two off, three on. So are Continental and Southern Swing. What separates each pair is not the days you work but whether your crew stays on one tour or rotates between days and nights.
It catches a lot of people out. Officers say they work Panama when they are on Pitman, and the difference is the whole argument of one of our comparisons.

Save it once and stop counting
Whatever it turns out to be called, you enter the pattern once and the calendar fills itself in — as far ahead as you want to look.
