How to read the result
If the end time is earlier than the start time, the calculator treats the shift as crossing midnight. This is a schedule check, not a payroll-grade timekeeping system.
FAQ
- Can I calculate a shift that crosses midnight?
- Yes. If the end time is earlier than the start time, the calculator treats it as the next day.
- Can I change the standard workday length?
- Not in the current version. The overtime reference is fixed at 8 hours.
- Does this include night differentials or payroll rules?
- No. This tool estimates worked hours and overtime only, and does not replace payroll-specific calculations.
