Why Adding Time Manually Is a Hassle

Let's be honest – adding time values isn't like regular addition. With 60 seconds in a minute and 60 minutes in an hour, it's easy to make mistakes when converting between units. Ever tried adding 2 hours 45 minutes to 1 hour 30 minutes and gotten confused? Our calculator takes care of all those conversions so you get accurate results every time.

It's simple:

  1. Enter your first time value in hours, minutes, seconds, and milliseconds
  2. Enter your second time value
  3. Click "Calculate Total" to see the sum of both times
  4. Use the "Load Example" button if you want to see how it works first

Our calculator shows you the total in multiple formats, making it easy to understand the result.
