All:

I stumbled upon this page while I was researching the initial post by DK. Not sure if this is still of help for you, but just so you know - I used the following function, which seems to work fine.

=(YEAR(B9)-YEAR(A9))*12+(MONTH(B9)-MONTH(A9))

I was looking for a solution to calculate # of months between 2 dates and run into this posting. Since I don't have the DatedIF function, I use the following workaround and it seems to work well:
=ROUND((EOMONTH(E21,0)-EOMONTH(D21,0))/30,0)

I needed to calculate amoritization counting every month as a whole month regardless of the date of the month the transcation begins and ends. Brets post sounded the most promising.
=DATEDIF(EOMONTH(I656,0),EOMONTH(J656,0),îmî)+IF(AND(EOMONTH(I656,0)=EOMONTH(J656,0),DATEDIF(I656,J656,îdî)>0),1,0)

I subsitiute a cell reference for the date - ie EOMONTH(g20,0)as above. Don't see any use for the IF statement added to the end.

Ignore my post above, I need more sleep. And this blog needs an “edit my comment” feature!

Maybe I’m missing some complication here, but why not just change the “equals” sign in your original formula to “less than or equal to”?
=DATEDIF(A1,B1,”m”)+IF(DAY(A1)<=DAY(B1),0,1)

ok, "not equal" sign didn't display. So here it is replaced with NEQ

=DATEDIF(0,B1,"m")-DATEDIF(0,A1,"m")+(DAY(A1) NEQ DAY(B1))-(MONTH(DATE(YEAR(A1),MONTH(A1),DAY(A1)+1)) NEQ MONTH(A1))

Hi Dick,

This worked for my test material. Not sure if I understood the problem corretly though:

=DATEDIF(0,B1,"m")-DATEDIF(0,A1,"m")+(DAY(A1)DAY(B1))-(MONTH(DATE(YEAR(A1),MONTH(A1),DAY(A1)+1))MONTH(A1))

- Asser

Instead of EOMONTH, use

DATE(YEAR(a1),MONTH(a1)+1,0)

DK:

As a non-tech guy, I cannot understand why you would want to calculate these dates. I guess I'll just observe the commentary to determine whether an adequate formula exists for this calculation.

Brett: I can't be sure end user has the ATP so EOMONTH is out.

Frank: Okay as long as they are in the same year, but that's not the case for any of the data I was working with.
