Understanding Elapsed Time

What is Elapsed Time?

Elapsed time is the amount of time that passes between two events. For example, if you start work at 9:00 AM and finish at 5:30 PM, the elapsed time is 8 hours and 30 minutes.

Calculation Methods

  • Duration: End time - Start time
  • End Time: Start time + Duration
  • Start Time: End time - Duration

Cross-Day Calculations

Example: Night shift from 10:00 PM to 6:00 AM

Start: 22:00:00 → End: 06:00:00 (next day)

Duration: 8 hours (crosses midnight)

24-Hour Format

• 12:00 AM = 00:00 (midnight)

• 1:00 PM = 13:00

• 11:59 PM = 23:59
