Time Duration Calculator Online – Calculate Hours and Minutes Easily

Intro

Keeping track of time is important in everyday life. Whether you’re logging work hours, calculating travel time, or just curious about the gap between two events, doing it manually can be confusing. That’s where the Time Duration Calculator online comes in.

This free tool instantly calculates the difference between two times, giving you the exact hours, minutes, and even seconds. It’s accurate, easy to use, and perfect for professionals, students, and anyone who wants quick results without errors.

Formula / Working

The basic formula behind a time duration calculation is: Duration=End Time−Start Time\text{Duration} = \text{End Time} – \text{Start Time}Duration=End Time−Start Time

Steps the calculator applies:

Convert both start and end times into a 24-hour format.
Break them into hours, minutes, and seconds.
Subtract the start time from the end time.
Adjust for cases where the end time is on the next day (crossing midnight).

Example:

Start Time = 9:15 AM (09:15)
End Time = 2:45 PM (14:45)

Duration=14:45−09:15=5 hours and 30 minutesDuration = 14:45 – 09:15 = 5 \, \text{hours and} \, 30 \, \text{minutes}Duration=14:45−09:15=5hours and30minutes

Here’s how to use the Time Duration Calculator online:

Enter the start time (hours, minutes, and seconds if needed).
Enter the end time.
Click on the “Calculate” button.
Instantly see the total duration in hours, minutes, and seconds.

Examples

Example 1

Start Time: 8:00 AM
End Time: 1:30 PM

Duration=5 hours 30 minutesDuration = 5 \, \text{hours 30 minutes}Duration=5hours 30 minutes

Result: 5 hours 30 minutes

Example 2

Start Time: 10:15 PM
End Time: 2:45 AM (next day)

Duration=(24:00−22:15)+02:45=1:45+2:45=4 hours 30 minutesDuration = (24:00 – 22:15) + 02:45 = 1:45 + 2:45 = 4 \, \text{hours 30 minutes}Duration=(24:00−22:15)+02:45=1:45+2:45=4hours 30 minutes

Result: 4 hours 30 minutes

Example 3

Start Time: 9:05 AM
End Time: 9:45 AM

Duration=40 minutesDuration = 40 \, \text{minutes}Duration=40minutes

Result: 40 minutes
