## How to Add Times Together

Adding two times or durations together might seem challenging, but it’s actually pretty easy if you follow a few simple steps.

Step One: start by adding the hours of each time, minutes of each time, and seconds of each time together separately.

If the minutes and seconds are both less than 60, then that’s it, you’re done!

Step Two: if the seconds are larger than 60, simply add 1 to the minutes and subtract 60 from the seconds.

Step Three: if the minutes are larger than 60, then add 1 to the hours and subtract 60 from the minutes.

At this point you should have a sum of the two times in hours, minutes, and seconds, great job!

If you want to find the total hours, minutes, or seconds check out our time to decimal calculator.

For example, add the times 1:30:45 and 2:45:20 together.

Add hours, minutes, and seconds separately:
hours = 1 + 2 = 3 hours
minutes = 30 + 45 = 75 minutes
seconds = 45 + 20 = 65 seconds

Seconds are greater than 60, so add 1 minute and subtract 60 seconds:
minutes = 75 + 1 = 76 minutes
seconds = 65 – 60 = 5 seconds

Minutes are greater than 60, so add 1 hour and subtract 60 minutes:
hours = 3 + 1 = 4 hours
minutes = 76 – 60 = 16 minutes

Thus, the sum of the times is 4:16:05. To subtract one time from another, use our subtract times calculator.
