In one column, I have 03:12:00 in hh:mm:ss format... in the next column, I have 32:00:00 in [hh]:mm:ss format.... when I add them together instead of getting 35:12:00, I am getting 587:12:00.

Basically, I am trying to add formulas to substract out weekend hours (Friday after 5, Saturday, Sunday, and Monday until 8) for a time ticket.... in the example above, the ticket was submitted Saturday night with 3:12:00 to go in the day.... I want to add 32 hours to that time to get the total time to deduct off the response time of a ticket

The total time is in the [hh]:mm:ss format... so it reads 62:48:00 in this example... I want to then subtract 35:12:00 fromt it and come up with 27:36:00

Hi Coach3131

In your post you talk a lot about formats and I'm afraid you are confusing formats and values. Excel uses the values of the cells to perform the operation. Formats are just aesthetics.

My guess is that in the cell that displays 3:10:00 you have 23 days and 3:10:00.

Format the first cell also with [h]:mm:ss to see the total value. I guess it will display 555:10:00, which is 23 days 3 hours and 10 minutes.
