Example Calculation
Let’s look at a practical example to understand how this works:
Scenario:
- Start Time: 18:45
- Add Hours: 5
- Add Minutes: 30
Calculation:
- 18:45 + 5 hours = 23:45
- 23:45 + 30 minutes = 00:15 (next day)
Result:
00:15
This shows how the calculator automatically rolls over to the next day when the total exceeds 24 hours.
