Formula to add 'Time' formatted cells

[telcocook]

Greetings.
This might seem like an easy question to most of the users on this site but I'm having a brain freeze.

I have two cells formatted as 'Category: Time and Type: 1:30 PM'.

In cell a:1 I enter 10:30 and get a result of 10:30 AM. Good so far.
In cell a:2 I enter 13:30 and get a result of 1:30 PM. Also what I would expect.

So, the time that has passed between these two cells is 3 hours. What formula do I use in cell a:3 to calculate the span of time between a:1 and a:2?

Thank you!

The basic answer is =(A2-A1)*24 and format the cell as GENERAL.

However, when doing this math, there is always the chance the time span will go past midnight. If that is ever the case, you will need this instead:
=((A2-A1)+(A1>A2))*24



Data Range

	A	B	C
1	10:30 AM	10:30 PM
2	1:30 PM	1:30 AM
3	3	3	=((A2-A1)+(A1>A2))*24

Thank you so very much Jerry! That was the perfect result that I was seeking.

Awesome.
