Direct answer
Treat the overnight shift as one continuous shift, calculate its paid hours, then place those hours in the correct workweek under your payroll rule.
The math is simple; the workweek assignment is where mistakes usually happen.
Use this when you are checking weekly hours when one shift starts on one date and ends after midnight. The strongest answer comes from the actual time clock export, timesheet, schedule, payroll correction, or manager approval, not from a remembered schedule or rough paycheck amount.
Open Time Card CalculatorFormula and realistic example
Formula: Weekly hours = daytime shifts + overnight shift paid hours - unpaid breaks, assigned to the proper workweek.
Example: A 10:00 PM to 6:30 AM shift is 8.5 hours long. With a 30-minute unpaid meal break, it adds 8.0 paid hours to the weekly total.
Keep the example visible while replacing the numbers. That catches the mistakes people usually miss: the wrong start date, a duplicate lunch deduction, the wrong rate, or a skipped holiday.

Copy-ready result
Overnight shift: 10:00 PM-6:30 AM, unpaid break 30 minutes, paid hours 8.0. Weekly total should include those 8.0 hours according to payroll's workweek assignment rule.
If you paste this into a payroll note, PTO request, invoice follow-up, or manager message, keep the assumption sentence with it. A number without the rule behind it is hard to check later.

Open Time Card CalculatorReal situations this covers
These are the kinds of everyday cases where a quick calculator answer is useful, but the notes still matter.
Key checks
- Security shift starts Sunday night and ends Monday morning.
- Nursing shift crosses midnight near the end of the payroll week.
- Warehouse shift crosses midnight during a holiday week.
Step-by-step method
Key checks
- Write down the clock-in time, clock-out time, break minutes, paid-break status, rounding rule, and workweek boundary.
- Check the source record: time clock export, timesheet, schedule, payroll correction, or manager approval.
- Apply this rule: Weekly hours = daytime shifts + overnight shift paid hours - unpaid breaks, assigned to the proper workweek.
- Run one clean scenario first, then add special cases only when they actually apply.
- Save the final number with the assumption note before using it for a timesheet correction, weekly-hours check, overtime review, or invoice note.
What can change the answer
The answer can change when automatic lunch deductions, paid breaks, rounded punches, overnight shifts, missed punches, split shifts, and training time affect the inputs. That is why the exact rule matters more than the title of the calculator.
When the result feels off, do not start by changing the final number. Go back to the start date, paid-hour rule, deduction type, holiday calendar, or pay-rate line and find the input that moved.
Key checks
- Ask whether payroll assigns the full shift to the start date, end date, or split by date.
- Keep date and time together in notes; 2:00 AM without a date is ambiguous.
- If the shift has a differential, calculate paid hours first and premium pay second.
Common mistakes
Key checks
- Do not stop the calculation at midnight and forget the post-midnight hours.
- Do not add the same overnight shift to both weeks.
- Do not check overtime until overnight hours are assigned to the correct workweek.
