What this calculator does
This hours and minutes calculator adds, subtracts and finds elapsed time in hours and minutes. 60 minutes equals 1 hour, and any minutes value of 60 or more is normalized automatically.
Formula
60 minutes = 1 hour Decimal hours = (total hours × 60 + total minutes) ÷ 60 Elapsed time: if end ≤ start, the end is counted on the following day.
Worked example
Examples: Adding 2 h 45 min and 1 h 35 min gives 4 h 20 min. Subtracting 2 h 45 min from 8 h 30 min gives 5 h 45 min. Elapsed time from 22:00 to 06:00 is 8 h 00 min (480 min, 8.00 decimal hours) because the span crosses midnight.
How the calculation works
- To add, enter hours and minutes on each row and use "Add row" for more values. Minutes are normalized automatically (for example, 90 min becomes 1 h 30 min).
- To subtract, enter two hours-and-minutes values; the calculator returns the difference.
- To find elapsed time, enter a start and end time. Spans that cross midnight are handled automatically.
