I'm using Excel 2000 and trying to use the datedif function. I've formated 2
columns as date m/dd/yyyy and left the formula column general I'm entering
dates
A1: 1/1/2002
B1: 1/1/2005

I'm entering the formula in C1
=datedif(b1,a1,"M")

I'm looking for the nmber of months between 2 dates

I get #NUM! for a result.

Thanks
John

The first date must be earlier than the second date. Try
=DATEDIF(A1,B1,"m")

See www.cpearson.com/excel/datedif.htm for more information.

From Chips' site http://www.cpearson.com/excel/datedif.htm



=DATEDIF(Date1,Date2,Interval)

Date1 must be less than (earlier) or equal to Date2. Otherwise, =DATEDIF
will return a #NUM! error. If either Date1 or Date2 is not a date, =DATEDIF
will return a #VALUE! error.

By the way:
You do not need to format cells before entering dates. Just type the data
as, for example, 1/1/2002 and Excel recognizes a date.

Hi John, datedif calculates de difference of the two dates, but the formula
must be

DATEDIF(INITIAL DATE,LAST DATE,TYPE OF DIF)

Try to put Datedif(a1,ba,"m")

hope this helps

Hi

For case earlier/later dates aren't ordered column-wise
=DATEDIF(MIN(A1,B1),MAX(A1,B1),"m")

Try reversing the order of b1 and a1. In the test I tried, that's how I got
rid of the #num error.

That's weird. I could have sworn when I looked at this question, there were
no replies. Then I replied and I see like 8 people have already answered.

It's the nature of the beast. You think you are the first reply and when you
come back there are several ahead of you. I also wish there wasn't the
delay. I think it has something to do with where you are but that's a guess.
