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 8am to noon is 4 hours, and from noon to 2:40pm is 2 hours 40 minutes.
6 hours 40 minutes is 1 hour 20 minutes short of 8 hours. Five of these shifts come to 33 hours 20 minutes a week, or 30 hours 50 minutes with a 30-minute unpaid break each day.
If you take a 30-minute unpaid break, 6 hours 10 minutes remain, which a timesheet in decimal hours shows as 6.17. 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: 08:00 and 14:40.
- Subtract. 14:40 − 08:00 = 6:40, which is 6 hours 40 minutes.
- For minutes, 6 × 60 + 40 = 400. For decimal hours, 400 ÷ 60 = 6.67, rounded to two places.
- With the break, 400 − 30 = 370 minutes, or 6 hours 10 minutes.
