Direct answer
Calculate each work period separately, subtract unpaid breaks inside each period, then add the paid periods together for the day.
A long unpaid gap between segments is not the same as a lunch break inside one continuous shift.
Use this answer for adding two or more separate work periods in the same day. Before relying on it, compare the inputs with your time card, schedule, payroll export, or manager-approved timesheet.
Open Time Card CalculatorFormula and worked example
Formula: Split shift hours = first paid segment + second paid segment + any other paid segments.
Example: 8:00 AM to 12:00 PM is 4.0 hours and 3:00 PM to 7:00 PM is 4.0 hours, so the day totals 8.0 paid hours.
Keep the formula and the example visible when you change inputs. That makes it easier to spot whether the difference came from hours, dates, pay frequency, or policy wording.

Step-by-step method
Key checks
- Write down the clock times, break minutes, schedule dates, rounding rules, and the workweek boundary before calculating.
- Calculate the simplest version first so the baseline is clear.
- Apply the rule: Split shift hours = first paid segment + second paid segment + any other paid segments.
- Adjust for unpaid breaks, overnight shifts, split shifts, rounded punches, holidays, weekends, and overtime cutoffs only when those details are part of the real situation.
- Compare the result with your time card, schedule, payroll export, or manager-approved timesheet before using it for a real timesheet, payroll estimate, schedule review, or work-hours note.
What can change the answer
The result can change when unpaid breaks, overnight shifts, split shifts, rounded punches, holidays, weekends, and overtime cutoffs are involved. That does not make the calculator unreliable; it means the inputs need to match the real rule.
If the result is for planning, a close estimate may be enough. If it affects pay, PTO, notice timing, or a formal deadline, use the official record as the final source.
A good habit is to change one input at a time. That shows whether the schedule, pay rate, date range, or policy detail caused the new result.
Common mistakes
Key checks
- Do not treat the gap between shifts as paid time unless policy says it is paid.
- Do not subtract the same unpaid break from both segments.
- Do not combine split shifts before checking overnight or overtime rules.
