About this shift
The shift starts in the morning and ends in the evening on the same date. It doesn't cross midnight, so the hours are a plain subtraction. From 8am to noon is 4 hours, and from noon to 5pm is 5 hours.
9 hours is 1 hour more than an 8-hour day. Four of these shifts come to 36 hours a week, and five come to 45 hours.
If you take a 30-minute unpaid break, 8 hours 30 minutes remain, which a timesheet in decimal hours shows as 8.5. 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.
How the hours are worked out
- Write both times in 24-hour form: 08:00 and 17:00.
- Subtract. 17:00 − 08:00 = 9:00, which is 9 hours.
- For minutes, 9 × 60 = 540. For decimal hours, 540 ÷ 60 = 9.
- With the break, 540 − 30 = 510 minutes, or 8 hours 30 minutes.
