Networkdays between 2 dates in different format

[qike74]

I'm trying to get the difference in hours between two dates which are displayed in a different format (one is in mm/dd/yyyy and the other is in dd/mm/yyyy). Changing the format cell doesn't help.
I'm trying different solutions without being able to succeed. Basically I would like to format the first one to display dd/mm/yyyy to make it work.

here is a sample:

Date Opened Date Closed Formula applied Result
8/1/2015 2:04 PM 14-01-2016 3:35 PM =SUM(((NETWORKDAYS(A2,B2)-1)*24),HOUR(B2-A2)) 6361 (Excel thinks the first is Jan and not August)
1/13/2016 12:04 PM 14-01-2016 3:35 PM =SUM(((NETWORKDAYS(A3,B3)-1)*24),HOUR(B3-A3)) #VALUE! (doesn't recognize 13 as a month I believe)

Any ideas? Thanks!!

It looks like the formatting in the message is quite difficult to read. please find below an easier version to read:

Date Opened
A1) 8/1/2015 2:04 PM
A2) 1/13/2016 12:04 PM

Date Closed
B1) 14-01-2016 3:35 PM
B2) 14-01-2016 3:35 PM

Formula to be applied:
=SUM(((NETWORKDAYS(A,B)-1)*24),HOUR(B-A))

Results:
Line 1: 6361 (Excel thinks the date opened is Jan and not August.)
Line 2: #VALUE! (Excel doesn't recognize 13 as a month I believe)

So you have some American dates that you have pasted into an English excel sheet? Can you not convert the dates before they are imported?

I guess I could use the text to column feature but I'm looking for an automated solution so anytime the file is refreshed there is no manual intervention.

In order to simplify things I changed the second date to NOW() as this is the refresh time and will be the same.
However, even formatting the NOW() date to the original American I'm getting the same error.

Here I have uploaded a sample for better visibility:

It would be so great if anybody could have a look and understand what could be done

Thanks!

You could convert your dates that are text as such. Bear in mind that A2 seems to be incorrect. It closes before it opens!

=DATEVALUE(SUBSTITUTE(REPLACE(A2,1,FIND("/",A2),""),"/","/"&LEFT(A2,FIND("/",A2))))+MOD(MID(A2,FIND(" ",A2)+1,99),1)
