Hours and Minutes Calculator
Hours and Minutes Calculator
Adding or subtracting clock time isn't as simple as regular arithmetic, since 60 minutes make an hour rather than 100. This calculator handles that conversion automatically — enter two durations in hours and minutes, choose whether to add or subtract them, and get an exact result without doing the carrying and borrowing by hand. It's a smaller, quicker alternative to a full h:m:s calculator for anyone who only needs to work with hours and minutes, such as tallying up work shifts or combining travel segments.
- Method: both durations are converted to total minutes, added or subtracted, then reformatted back to h:m.
- Example: 3:45 + 1:30 = 5:15 (3h45m = 225 min, 1h30m = 90 min, total 315 min = 5h15m).
- Negative results: subtracting a larger duration from a smaller one shows a minus sign.
What is 2:50 + 0:20?
170 + 20 = 190 minutes = 3:10.
Can I use this for timesheets?
Yes — it's ideal for combining shift lengths recorded in hours and minutes.
