About the Time Duration Calculator

The Time Duration Calculator is a useful tool for determining the amount of time between two given times. It's particularly helpful for time management, scheduling, and various other applications where precise time intervals are needed.

What is Time Duration?

Time duration refers to the length of time that elapses between two specific points in time. It's typically expressed in hours and minutes, and sometimes in seconds for more precise measurements.

Formula for Calculating Time Duration

The basic formula for calculating time duration is:

\[Duration = End Time - Start Time\]

Where:

  • \(Duration\) is the time interval between the start and end times
  • \(End Time\) is the later time point
  • \(Start Time\) is the earlier time point

Calculation Steps

  1. Convert both start and end times to a 24-hour format if necessary.
  2. Convert both times to minutes since midnight.
  3. Subtract the start time from the end time.
  4. If the result is negative, add 1440 (number of minutes in a day).
  5. Convert the result back to hours and minutes.

Example

Let's calculate the duration between 9:30 AM and 2:45 PM:

\[9:30 AM = 570 \text{ minutes}\] \[2:45 PM = 885 \text{ minutes}\] \[885 - 570 = 315 \text{ minutes}\] \[315 \text{ minutes} = 5 \text{ hours and } 15 \text{ minutes}\]
Time Duration Calculation: 9:30 AM to 2:45 PM 9:30 AM (570 minutes) 2:45 PM (885 minutes) 5 hours 15 minutes (315 minutes) 885 minutes - 570 minutes = 315 minutes 315 minutes = 5 hours and 15 minutes
