US Hours Between Times Calculator — How It Works

Calculates the duration in hours and minutes between two times of day.

How it works

  1. Enter a start time and an end time.
  2. The tool calculates the difference in hours and minutes.
  3. If the end time is earlier than the start time, it assumes the range crosses midnight and adds 24 hours.

Example

A shift from 09:00 to 17:30 is 8 hours, 30 minutes (510 minutes total). A night shift from 22:00 to 06:00 is 8 hours, 0 minutes — the calculator automatically wraps past midnight.

Is this accurate?

The calculator performs the math precisely, but for dates that depend on local rules (holidays, time zone changes, medical estimates), treat the result as a planning guide rather than an official figure.
