Calculate work hours from clock-in, clock-out, and break time.

Category: Date & Time

When to use?

Use it to find actual work hours (minus breaks) and any overtime beyond 8 hours from clock-in/clock-out records.

How to use

  • Enter clock-in and clock-out times.
  • Enter break time in minutes.
  • See total time on site, actual work hours, and overtime beyond 8 hours.

Input Explanation

If clock-out is earlier than clock-in, it is treated as the next day. Break time is between 0 and 1,440 minutes.

Calculation Basis

It subtracts break time from total time on site for actual work hours, and separately shows any portion over 8 hours.

Usage Examples

  • Check daily work records - Quickly calculate actual work hours before entering a timesheet.
  • Check overtime - Find overtime worked beyond 8 hours.
  • Settle part-time hours - Settle hours worked from clock-in/out times and breaks.

Examples

  • 09:00–18:00, 60-min break → 8 hours worked
  • 22:00–06:00, 30-min break → 7 hours 30 minutes worked

Cautions

  • Rules for deducting lunch and mandatory break time should be adjusted to labor law and company policy.
  • Time-zone settings can cause a one-day difference in some cases.
