Month Deduct Formula needed

[K]

Hi all, I am trying to create month deduct formula below but not
having any success. In below data I got current date in cell A1 and
various dates in column D and then in column E in cell E1 I have
formula "=Month($A$1)-Month(D1)" which then continue to down. As you
can see in below data in cell E1 i am getting result which is "-5" as
it should be "7" because if you count months from date "19/06/2009" to
"01/11/2008" they are "7". I am trying to get postive figure in
column E and as you can see there are few results in negative figures
and also incorrect.

A D E -----col
19/06/2009 01/11/2008 -5
12/12/2008 -6
15/03/2009 3
16/10/2009 -4

The result should come something like below

A D E----col
19/06/2009 01/11/2008 7
12/12/2008 6
15/03/2009 3
16/10/2009 4

I need this formula also for conditional formatting as I am tring to
hilight rows in which dates are six months old from current date.
Please can any friend help me.

You could try something like this but it does give slightly different
results than you expect.

=IF($A$1>B1,DATEDIF(B1,$A$1,"m"),DATEDIF($A$1,B1,"m"))
