Quick answer
8:00 AM to 4:30 PM is 8 hours 30 minutes elapsed. Subtract a 30-minute unpaid lunch and the result is exactly 8 paid hours.
Formula or method
8.5 elapsed hours − 0.5 unpaid hour = 8.0 paid hours
Step-by-step
- Find elapsed time: 8:00 AM to 4:30 PM = 8.5 hours.
- Convert the 30-minute lunch to 0.5 hour.
- Subtract the lunch to get 8.0 paid hours.
Worked example
The shift lasts 510 minutes. Subtract 30 unpaid minutes to get 480 paid minutes. 480 ÷ 60 = 8.00 hours.
How to interpret the result
This is the paid-time total only. Whether a break is paid or unpaid depends on the workplace and applicable rules.
Common mistakes
- Subtracting 30 as if it were 0.30 hour.
- Counting 4:30 PM as 4.30 in decimal time.
- Ignoring whether the break is paid.
