Direct answer
Count the full overnight span, then subtract both unpaid meal breaks from the same shift total.
Crossing midnight changes the date, not the basic paid-hours rule.
Use the answer as a working number, then compare it with the source that controls the situation: schedule, pay stub, PTO ledger, HR message, invoice terms, or policy wording.

Formula: Paid hours = end time after midnight - start time before midnight - total unpaid meals.
Example: A 6:00 PM to 6:00 AM shift with two 30-minute unpaid lunches equals 11 paid hours.
Write the assumption beside the result. A reviewer should be able to see whether the answer changed because of hours, dates, deduction timing, break treatment, or a policy exception.

Step-by-step method
Key checks
- List the start times, end times, lunch length, paid breaks, shift dates, rounding rule, and the workweek boundary before calculating.
- Start with the plain case. Add the unusual item afterward so the difference is visible.
- Apply this rule: Paid hours = end time after midnight - start time before midnight - total unpaid meals.
- Add adjustments only when rounded punches, missed lunches, paid rest breaks, overnight shifts, split shifts, holiday work, and custom workweeks are actually part of the situation.
- Compare the estimate with your time clock export, schedule, manager correction, payroll note, project log, or written timekeeping policy before relying on it.
What can change the answer
The result can change when rounded punches, missed lunches, paid rest breaks, overnight shifts, split shifts, holiday work, and custom workweeks affect the inputs.
That does not make the calculator less useful. It means the calculator should mirror the real rule instead of the clean example.
The calculator can show the math, but the source record decides whether that math applies.
Common mistakes
Key checks
- Do not stop at midnight and forget the second half.
- Do not subtract only one lunch when two were unpaid.
- Do not put the whole shift on the wrong workweek without checking payroll cutoff.
Use the related calculator
Use Time Card With Lunch Calculator when you want to test the exact numbers instead of trusting a shortcut.
Copy the result with the assumptions beside it: dates, hours, pay rate, break treatment, deduction period, or policy detail.
If one assumption moves the result by a lot, keep both scenarios instead of overwriting the first answer.
