About this shift
The shift starts in the small hours and ends at noon on the same date. It doesn't cross midnight, so the hours are a plain subtraction. It runs from 2am until noon, so all 10 hours are morning hours.
10 hours is 2 hours more than an 8-hour day. Four of these shifts come to 40 hours a week, and five come to 50 hours.
If you take a 30-minute unpaid break, 9 hours 30 minutes remain, which a timesheet in decimal hours shows as 9.5. The 30 minutes is an example, not a legal rule. Break and overtime rules depend on your contract and where you work. This page gives clock time only.
12pm is noon and 12am is midnight.
How the hours are worked out
- Write both times in 24-hour form: 02:00 and 12:00.
- Subtract. 12:00 − 02:00 = 10:00, which is 10 hours.
- For minutes, 10 × 60 = 600. For decimal hours, 600 ÷ 60 = 10.
- With the break, 600 − 30 = 570 minutes, or 9 hours 30 minutes.
