Hours are the full shift length: breaks are not subtracted and clock changes are not counted.

What 4 on 4 off looks like in a year

The cycle is eight days long, so your days off move through the week: a run that ends on a Friday this time ends on a Saturday next time. Starting on 1 January, 2027 has 184 working days and 181 days off, which makes 2,208 hours at 12 hours a shift.

That moving pattern is the reason a printed calendar helps: it is hard to work out in your head whether a date three months away is a working day. Two crews on the same site usually run four days apart, so move the start date by four days to see the other crew.

Day and night runs

If your runs are nights, set the shift to start in the evening and end in the morning. Keep in mind that the first night then ends on the following morning, which the calendar still shows under the day the shift started.
