Result

From 9:00 in the morning to 5:00 in the afternoon is exactly 8 hours. This page opens the duration calculator with 09:00 and 17:00 already filled in, so the classic 9-to-5 result is one click away — and you can adjust either time to match your real schedule.

The paid time usually differs from the clock time: with a 30-minute unpaid lunch a 9-to-5 day counts as 7.5 worked hours, and with a full one-hour break it drops to 7 hours. Type the break into the minutes field and the calculator deducts it before showing hh:mm, decimal hours, and total minutes.

The decimal figure matters for payroll: 7:30 on the clock is 7.5 hours on an invoice, not 7.3. Whatever break you set, this calculator converts the result for you — entirely in your browser.

Accepted Formats & Rules

  • Time between two clock times with optional break
  • Add or subtract two hh:mm durations
  • Results in hh:mm, decimal hours, and minutes

Key Benefits

✓ Overnight spans are detected automatically when the end time is earlier than the start.
✓ Every result comes in hh:mm, decimal hours, and total minutes at once.
✓ A second mode adds or subtracts two hh:mm durations without base-60 mistakes.

Use Cases

  • • Find out exactly how long a shift lasts: pick the start and end times, subtract the lunch break, and read the result in hh:mm and decimal hours.
  • • Calculate an overnight span like 9pm to 5am — the calculator adds 24 hours automatically when the end time is earlier than the start.
  • • Add two hh:mm durations, such as timesheet entries or flight legs, with minutes carried correctly instead of decimal guesswork.
