Practical Examples

Example 1: Calculate Duration

  • Start Time: 9:30 AM
  • End Time: 2:45 PM
  • Calculation: The duration between times is 5 hours and 15 minutes.

Example 2: Add Hours to a Time

  • Current Time: 3:15 PM
  • Add: 4 hours 30 minutes
  • Calculation: Resulting Time = 7:45 PM

Example 3: Subtract Time

  • Current Time: 5:00 PM
  • Subtract: 2 hours 20 minutes
  • Calculation: Resulting Time = 2:40 PM

Example 4: Multiple Time Durations

  • Task 1: 1 hour 45 minutes
  • Task 2: 2 hours 30 minutes
  • Task 3: 3 hours 15 minutes
