About this shift
The shift starts in the morning and ends late in the evening on the same date. It doesn't cross midnight, so the hours are a plain subtraction. From 11am to noon is 1 hour, and from noon to 9:30pm is 9 hours 30 minutes.
10 hours 30 minutes is 2 hours 30 minutes more than an 8-hour day. Four of these shifts come to 42 hours a week, and five come to 52 hours 30 minutes.
If you take a 30-minute unpaid break, 10 hours remain, which a timesheet in decimal hours shows as 10. 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.
How the hours are worked out
- Write both times in 24-hour form: 11:00 and 21:30.
- Subtract. 21:30 − 11:00 = 10:30, which is 10 hours 30 minutes.
- For minutes, 10 × 60 + 30 = 630. For decimal hours, 630 ÷ 60 = 10.5.
- With the break, 630 − 30 = 600 minutes, or 10 hours.
