How Long Is an 8 Hour Shift? (Starting at 7am, 9am & More)
An 8 hour shift is eight hours of clock time — but the number of hours you actually get paid for, and the time you can finally go home, depends entirely on your break. Here is exactly how it works.
The Short Answer
An 8 hour shift means 8 hours between when you clock in and clock out. The catch is the break:
- Paid break: all 8 hours are paid, and you are on site for 8 hours.
- 30-minute unpaid lunch: you are paid for 7.5 hours, but on site for 8.5 hours.
- 1-hour unpaid lunch: you are paid for 7 hours, but on site for 9 hours.
This is the single biggest source of confusion: "8 hour shift" usually describes paid hours, while the time you are physically at work can be longer because of an unpaid lunch.
8 Hour Shift Starting at 7am
This is one of the most common shift patterns, and a very common search. Starting at 7:00 AM:
| Break | You leave at | Paid hours |
|---|---|---|
| Paid break (no unpaid lunch) | 3:00 PM | 8.0 |
| 30 min unpaid lunch | 3:30 PM | 7.5 |
| 1 hour unpaid lunch | 4:00 PM | 7.0 |
Common 8 Hour Shift Times
Here is what an 8-hour clock-time shift looks like for popular start times (before any unpaid break is added):
| Start | End (8h clock time) | Common name |
|---|---|---|
| 7:00 AM | 3:00 PM | Early day shift |
| 8:00 AM | 4:00 PM | Day shift |
| 9:00 AM | 5:00 PM | 9 to 5 |
| 11:00 AM | 7:00 PM | Mid shift |
| 3:00 PM | 11:00 PM | Evening / swing shift |
| 11:00 PM | 7:00 AM | Night / graveyard shift |

What About a 10-5 Shift?
A "10-5 shift" (10:00 AM to 5:00 PM) is a frequent question, and it is not an 8-hour shift — it is 7 hours of clock time, or 6.5 paid hours after a 30-minute unpaid break. Always count the actual start and end times rather than assuming every shift is 8 hours.
8 vs 10 vs 12 Hour Shifts
Once you understand the 8-hour shift, longer shifts follow the same logic — they just trigger overtime sooner:
| Shift | Clock time | Paid (30-min break) | Overtime hrs* |
|---|---|---|---|
| 8 hour | 8h | 7.5 | 0 |
| 10 hour | 10h | 9.5 | 1.5 |
| 12 hour | 12h | 11.5 | 3.5 |
*Assuming a daily 8-hour overtime rule. See our full guide to calculating overtime pay.

How long is an 8 hour shift?
An 8 hour shift is 8 hours of clock time start to finish. If the break is unpaid, paid time is less — a 30-minute unpaid lunch makes 7.5 paid hours, and a 1-hour lunch makes 7. If breaks are paid, all 8 hours are paid.
What time does an 8 hour shift end if it starts at 7am?
Starting at 7:00 AM it ends at 3:00 PM with paid breaks. With a 30-minute unpaid lunch you usually leave at 3:30 PM; with a 1-hour lunch, 4:00 PM, because the unpaid break extends your time on site.
What time does a 9 to 5 finish as an 8 hour shift?
9:00 AM to 5:00 PM is 8 hours of clock time. With a 30-minute unpaid lunch you are paid for 7.5 hours; with a paid break, the full 8 hours.
How many hours is a 10-5 shift?
10:00 AM to 5:00 PM is 7 hours of clock time. After a 30-minute unpaid break you are paid for 6.5 hours.
Does an 8 hour shift include lunch?
It depends on the employer. Many add an unpaid lunch on top of the 8 hours, so you are on site 8.5 to 9 hours. Others include a paid break inside the 8. Check your specific policy.
