How to use this hours and minutes calculator

Hours and minutes calculator is two-operand duration math with carry (50m + 25m = 1h 15m extra). The Hours Calculator sums up to six segments. Time Calculator adds a duration to a clock time instead.

Formula

Convert each duration to hours, add or subtract, then display as hours:minutes and decimal.

Worked example

3h 50m + 2h 25m = 6h 15m (6.25 hours). 8h 10m − 0h 25m = 7h 45m.
