Understanding how to calculate time durations is essential in various aspects of life, from scheduling meetings to planning projects. This guide will help you learn how to effectively calculate time durations.

Basic Concepts of Time

To calculate time durations accurately, you first need to understand the basic units of time:

Seconds (s)
Minutes (min) - 1 minute = 60 seconds
Hours (h) - 1 hour = 60 minutes
Days - 1 day = 24 hours

Step-by-Step Guide to Calculate Time Durations

1. Determine the Start and End Time

Identify the start and end time of the event or activity you are measuring. For example:

Start Time: 2:30 PM
End Time: 4:15 PM

2. Convert Time to a Common Unit

For easier calculations, it is helpful to convert both times into the same unit. You can convert everything into minutes for this example.

Start Time:
- 2:30 PM = 2 hours × 60 minutes/hour + 30 minutes = 150 minutes
End Time:
- 4:15 PM = 4 hours × 60 minutes/hour + 15 minutes = 255 minutes

3. Calculate the Duration

Subtract the start time from the end time to find the duration.

Duration:
- 255 minutes - 150 minutes = 105 minutes

4. Convert Back to Hours and Minutes

If you want to convert the duration back into hours and minutes, you can do so:

105 minutes = 1 hour and 45 minutes

Examples of Time Duration Calculations

Example 1: Meeting Duration

Start Time: 9:00 AM
End Time: 10:30 AM

Calculation:

9:00 AM = 540 minutes
10:30 AM = 630 minutes
Duration: 630 - 540 = 90 minutes = 1 hour and 30 minutes

Example 2: Project Time Calculation

Start Time: 1:15 PM
End Time: 3:45 PM
