About this shift
The shift starts in the afternoon and stops exactly at midnight, so all of it is on the start date. Written as 12am the end looks earlier than the start, but it closes the same day. It begins at 4pm, 4 hours after noon, and runs to the end of the day.
Five 8-hour shifts make 40 hours a week. With a 30-minute unpaid break each day, the paid total is 37 hours 30 minutes.
If you take a 30-minute unpaid break, 7 hours 30 minutes remain, which a timesheet in decimal hours shows as 7.5. 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.
12pm is noon and 12am is midnight.
How the hours are worked out
- Write both times in 24-hour form. 16:00 is the start, and midnight at the end of the day counts as 24:00.
- Subtract. 24:00 − 16:00 = 8:00, which is 8 hours.
- For minutes, 8 × 60 = 480. For decimal hours, 480 ÷ 60 = 8.
- With the break, 480 − 30 = 450 minutes, or 7 hours 30 minutes.
