Duration calculation method
The tool combines each selected date and time, subtracts the start timestamp from the end timestamp, rounds to the nearest minute, and presents the same interval as hours-and-minutes, decimal hours, and total minutes.
Example check: 09:15 to 17:45 on the same date is 8 hours 30 minutes, 8.5 decimal hours, and 510 total minutes.
