Hours Between Times
This calculator is a simple yet powerful tool for measuring the duration between two times on the same day. Whether you're tracking work hours, logging study sessions, or calculating time spent on a project, this tool gives you the precise duration. You can also account for breaks to get a more accurate picture of your productive time.

Decimal hours are useful for payroll calculations where an hourly rate is applied.

Calculation Explained

How the Duration is Calculated

The process for calculating the net duration between two times is straightforward:

  1. Gross Duration: The calculator first determines the total duration between the start and end times in milliseconds.
  2. Subtract Break: The specified break time (in minutes) is converted to milliseconds and subtracted from the gross duration.
  3. Convert to Hours: The resulting net duration in milliseconds is then converted into hours. This is presented in two ways:
    • Hours & Minutes (HH:MM): A standard time format.
    • Decimal Hours: A single number representing the total hours (e.g., 7.5 for 7 hours and 30 minutes), which is useful for billing.

Example Calculation

Using the times you provided:

  • Start Time: 09:00
  • End Time: 17:00
  • Break: 30 minutes

The total time from start to end was calculated. After subtracting the 30-minute break, the final duration is 07:30, which is equivalent to 7.50 decimal hours.
