Short answer
Use the confirmed shift start, shift end, and actual unpaid lunch duration. The exact lunch clock time matters less for paid hours than the unpaid minutes, unless policy requires the lunch window.
For payroll math, duration usually drives the total. For compliance or manager review, the actual lunch window may still matter.
Open Time Card With Lunch CalculatorThe fast way to diagnose it
Working rule: Paid hours = shift end - shift start - confirmed unpaid lunch duration.
Realistic example: If you worked 8:00 AM to 4:30 PM and remember taking a 30-minute unpaid lunch, paid hours are 8.0 even if you do not remember whether lunch started at 12:10 or 12:25.
Key checks
- Confirm clock-in and clock-out times.
- Use the actual unpaid lunch duration if you know it.
- Mark the lunch window as approximate if required.
- Ask for correction rather than inventing a precise time.

How to read the result like a real record
A known 30-minute unpaid lunch gives enough information for paid-hour math.
A guessed lunch time can create audit problems if the system requires exact meal punches.
If lunch was interrupted by work, the duration may not be a normal unpaid lunch.
