Formula used
The calculation is performed using simple time addition:
Result = Starting Time + 30 minutes
If the addition crosses the hour boundary (e.g., 1:45 + 30 minutes), the hour is incremented and AM/PM is adjusted if necessary.
The calculator handles all edge cases, including:
- Adding 30 minutes to times near the hour boundary (e.g., 1:45)
- Changing from AM to PM when crossing noon
- Properly formatting the result in 12-hour time format
