Hours & Minutes Calculator adds or subtracts time durations in hours and minutes when decimal hours would confuse a timesheet.
Enter Time A and Time B as H:MM values such as 2:30 or 0:45, choose the operation, and calculate the combined or remaining duration.
This is duration math, not clock arithmetic across midnight with dates. For zone conversions, use the time zone tool instead.

It performs duration addition or subtraction on two H:MM style inputs.
- Time A and Time B fields in H:MM form
- Operation control to add or subtract
- Calculate action for the resulting duration
- Hint examples like 2:30 and 0:45

Tips and limits
- Use a colon format; values like 2.5 hours are not the same as 2:30 here.
- When subtracting, Time A should be the larger duration if you expect a positive result.
- Do not treat the fields as clock times of day unless your workflow truly means durations.
- Round according to your payroll rules after you calculate.
