This calculator adds or subtracts two h:m durations, e.g. 3:45 + 1:30 = 5:15.

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.
