About this shift
The shift starts at noon and ends late in the evening on the same date. It doesn't cross midnight, so the hours are a plain subtraction. It begins right at noon and finishes at 11pm, 1 hour before midnight.
11 hours is 3 hours more than an 8-hour day. Four of these shifts come to 44 hours a week, and five come to 55 hours.
If you take a 30-minute unpaid break, 10 hours 30 minutes remain, which a timesheet in decimal hours shows as 10.5. 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: 12:00 and 23:00.
- Subtract. 23:00 − 12:00 = 11:00, which is 11 hours.
- For minutes, 11 × 60 = 660. For decimal hours, 660 ÷ 60 = 11.
- With the break, 660 − 30 = 630 minutes, or 10 hours 30 minutes.
