About this shift
The shift starts in the morning and ends in the afternoon on the same date. It doesn't cross midnight, so the hours are a plain subtraction. From 9am to noon is 3 hours, and from noon to 1pm is 1 hour.
4 hours is 4 hours short of 8 hours. Five of these shifts come to 20 hours a week, or 17 hours 30 minutes with a 30-minute unpaid break each day.
If you take a 30-minute unpaid break, 3 hours 30 minutes remain, which a timesheet in decimal hours shows as 3.5. The 30 minutes is an example, not a legal rule. Whether you get a break, and whether it is paid, depends on your employer and where you work.
How the hours are worked out
- Write both times in 24-hour form: 09:00 and 13:00.
- Subtract. 13:00 − 09:00 = 4:00, which is 4 hours.
- For minutes, 4 × 60 = 240. For decimal hours, 240 ÷ 60 = 4.
- With the break, 240 − 30 = 210 minutes, or 3 hours 30 minutes.
