Let's say I have some data I parsed. And the time format is the following:

hh:mm:ss (24hr format)

i.e 15:13:09

I want to subtract the two times and get an overall duration value.

i.e 10:00:00 - 9:30:00 = 00:30:00

or something of that nature.. thanks.
 
Hi,

If your times are in A1 and B1, then the difference is
[tt]
=B1-A1
[/tt]
formatted [h]:mm:ss

I just found out that I could utilize DateDiff(), DateAdd()
however I want to know how to add days as well..

i.e Sat + 1 -> Sun, Sun + 2 -> Tue

Thanks.
 
Dates are just numbers. like today is 38224.

So you just ADD days to you date
Code:
MyDate = Date
MyDate = MyDate + 7
is wednesday september 1, 2004

Hi djmc,

Skip is correct (of course [smile]) but what App are we talking here, Excel or Access? And where in the app are your dates - in a worksheet cell, in a table field, in a VBA variable?

If the simple addition doesn't cut it, why not look at the Help for DateAdd - you can specify the units, and positive or negative quantities.

Enjoy,
Tony

I often use YEAR(B12)-YEAR(C12), then just format the cell that you are displaying the result as a number.

Hope it helps!
