Use this Time Duration Calculator to quickly calculate the total duration between two times. Whether you want to add or subtract hours and minutes, or calculate a span in hours, minutes, seconds, this tool helps you accurately measure time intervals.

It's ideal for figuring out work hours, travel time, or any event duration. Simply enter the start and end times, and the calculator will display the duration between two times in an easy-to-understand format.

What This Calculator Can Do

  • Calculate duration in hours and minutes
  • Display results in hours, minutes, seconds for longer time periods
  • Support both 12-hour and 24-hour time formats
  • Works as a time and date duration calculator for more advanced needs

How It Works

  1. Enter the start time: Use the correct format (e.g., 08:30 AM or 14:45).
  2. Enter the end time: Specify the ending point for the duration.
  3. Click "Calculate": The calculator will determine the total elapsed time.
  4. View the result: You'll get the total time in hours and minutes, or in hours, minutes, seconds if the duration spans across hours.

Example Use Cases

  • Calculate work shift hours from 9:00 AM to 5:30 PM
  • Determine flight duration between two time zones (if dates are supported)
  • Track project or task duration using start and end timestamps

Frequently Asked Questions

1. Can I use this to add or subtract time manually?

Yes. You can enter a start and end time to add or subtract the difference. For manual time math, just set one value as the base and the other as the time you want to offset.

2. Does it work with 24-hour time format?

Absolutely. The calculator supports both 12-hour (AM/PM) and 24-hour formats. Just ensure you input times consistently.

3. Can it calculate across multiple hours?

Yes. If your start and end times span multiple hours, the calculator will return the result in hours, minutes, seconds, making it ideal for long-duration calculations.
