How Time Duration Is Calculated
This calculator determines the time difference by subtracting the start time from the end time.
It automatically handles:
- Overnight time calculations

If the end time is earlier than the start time, the calculator assumes the time continues into the next day.

Start Time: 9:30 AM
End Time: 5:45 PM
Total Duration: 8 hours and 15 minutes
If the end time is earlier than the start time, the calculator assumes the time passes into the next day.

Start: 10:00 PM
End: 6:00 AM
Result: 8 hours
