Hours Calculator

Calculate shift length, break deductions, overnight work, and paid hours from start and end times.

이 도구에 대해

Calculate working hours for standard, part-time, and overnight shifts, then subtract breaks to get a clean paid-hours total.

Hours Calculator is built for real shift and payroll planning tasks, especially when breaks, overnight work, or weekly totals make the math annoying to do manually. It is more practical than a simple start-minus-end time subtractor.

  • Measures raw shift length from start and end times.
  • Subtracts break minutes automatically.
  • Handles overnight shifts that cross midnight.

사용 방법 Hours Calculator

Enter the shift start and end times, subtract unpaid breaks, and review the paid-hours result. If you are planning weekly totals or overtime, use the weekly settings so regular and overtime hours stay clearly separated.

When this tool is useful

  • Calculate paid hours for standard, part-time, or overnight shifts before payroll review.
  • Check whether break deductions are pushing a shift below a target paid-hours threshold.
  • Estimate staffing coverage when schedules cross midnight or change between weekdays and weekends.

Practical tips

  • Treat paid hours and scheduled hours separately so break deductions stay visible to managers and staff.
  • Use overnight presets when testing shifts that cross midnight because those are where spreadsheet mistakes usually happen.
  • Pair this with business-day or date-difference tools when you need both daily shift math and multi-day planning.

Work-hour calculations are usually tied to payroll, staffing, or compliance checks where small mistakes matter. A stronger page makes the breakdown visible instead of returning one opaque number.

Frequently asked questions

Can this calculate overnight shifts?

Yes. If the end time is earlier than the start time, the tool treats it as an overnight shift.

Does it subtract unpaid breaks?

Yes. Enter break minutes and the tool will calculate paid time after the deduction.

How does the tool handle shifts that cross midnight, like 10 PM to 6 AM?

The calculator correctly detects overnight shifts and calculates the elapsed hours across the midnight boundary without requiring you to enter separate date values.

Can I subtract a lunch break or multiple breaks from the total shift hours?

Yes, enter your break duration and the tool deducts it from gross shift hours to give you the net paid hours worked.

Does the output show hours in decimal format for payroll purposes?

Yes, the result is displayed in both hours-and-minutes and decimal-hours formats so you can paste the decimal value directly into payroll systems.
