Continental Shift Pattern: How the 28-Day Rota Works

How the 28-day continental cycle is built

A continental shift pattern covers 24 hours with three 8-hour shifts — early, late and night — and four crews. On any day three crews are working and one is off. Each crew follows the same 28-day sequence, a week apart from the next crew:

• Week one: 2 earlies, 2 lates, 3 nights.
• Then 2 days off, 2 earlies, 3 lates, 2 nights.
• Then 2 days off, 3 earlies, 2 lates, 2 nights.
• Then 3 days off, and the cycle starts again.

As letters, with D for early, S for late (swing) and N for night, Crew A's cycle is DDSSNNNOODDSSSNNOODDDSSNNOOO: 21 shifts in 28 days, no more than 7 in a row and a 3-day break at the end. The chart shows all four crews from Monday, January 5, 2026.

Forward rotation: early, then late, then night

Every block in the continental moves forward through the day: earlies, then lates, then nights. Each change of shift starts later than the one before, so you go to bed later rather than earlier — which shift-work guidance generally recommends, because most people find it easier to stay up late than to fall asleep early. The short blocks also mean no more than three nights in a row. The trade-off is that you change shift type often, roughly every two or three days, rather than settling into one for a week as on a DuPont or a Southern swing.

Hours, overtime and weekends

Twenty-one 8-hour shifts every 28 days is 42 hours a week on average. Over 2026 each crew works 273–274 shifts; Crew A in our example works 274 shifts, 92 of them nights, for 2,192 hours. Week by week the load is uneven — the first week holds seven shifts in a row:

With overtime after 40 hours in a Sunday-to-Saturday week, Crew A earns 104 overtime hours in 2026; counted Monday to Sunday the long first week is 56 hours and the total roughly doubles. Common examples: the US FLSA rule of overtime after 40 hours in a workweek; in the UK, the Working Time Regulations limit average weekly hours rather than setting an overtime rate. Your employer's rules and your contract decide. Full weekends off are rarer than on 12-hour rotations — one in every four weeks, 13 in 2026 — because there are only three short breaks per cycle.

Earlies and lates: the UK continental rota

In the UK the continental is usually written as a rota of earlies, lates and nights, often with shifts at 06:00–14:00, 14:00–22:00 and 22:00–06:00. To match, open More options in the generator, set the three start times, choose Monday as the first day of the week and the UK holiday region so bank holidays appear on the calendar — or load this UK continental rota with those settings already in place. US sites tend to say day, swing and night (or "mids"), and the default 07:00, 15:00 and 23:00 starts reflect that.

Pros and cons of the continental pattern

Continental vs DuPont, Southern swing and 4 on 4 off

All four rotations give 42 hours a week. The Southern swing (also in the generator) uses the same 8-hour shifts but in week-long blocks — 7 days, 2 off, 7 swings, 2 off, 7 nights, 3 off — so you change shift type only three times a cycle but work seven in a row each time; it gives 13 full weekends off in 2026. The DuPont covers the same operation with 12-hour shifts: 14 shifts per 28 days instead of 21, and a 7-day break. 4 on 4 off is the simplest 12-hour alternative, an 8-day cycle with four-day breaks. If your site is choosing between 8 and 12 hours, the 12-hour shift schedule guide lists every 12-hour option, including the 2-2-3, its Panama variant and the Pitman; fire services should see the firefighter shift calendar and the Kelly schedule.

A note on 12-hour "continental" rotas

Some employers use "continental" for any rotating 24/7 rota, including 12-hour ones such as two days, two nights and four days off. The pattern on this page is the 8-hour, three-shift version. For a 12-hour rota, choose the closest preset — DDNNOO, 4 on 4 off or DuPont — or build your exact sequence in the custom cycle builder on the shift calendar generator, which checks that your crews cover every day.
