IF calculation using dates - brain hurts

[Theo]

I have a date range:
From:8/5/2009
To: 11/19/2009

I have Month/Year Column and then a Result Column; in the Result Column I
need a formula that will determine if the month and year is within the above
date range.
Jul 09 Formula should return No
Aug 09 Formula should return Yes

Any suggestions?
Thanks
T

Where f13 is the from date and f14 is the to date and f15 is the date to
check.
=IF(AND(F15>$F$13,F15<=$F$14),"Yes","No")

It doesn't work because the from Date is 8/4/2009 and the date I'm checking
is Aug-2009 (which Excel is reading as 8/1/2009).
Somehow I need the check to be against just the month and year, but I can't
figure out how to do that. OR I need to do some type of LOOKUP where Aug
2009 is a series of dates between 8-1 and 8-31 and the from date just has to
be one of them. But I'm struggling with that one too.
Thanks Don

Assuming you are looking for an Excel formula solution, not VBA, one
approach is:

=if(date(year(A1),month(A1),1) = date(year(A2),month(A2),1),"same
month/year","not same month/year")

Note: You can avoid one of the DATE functions if you want to assume that
the cell is always mm/1/yyyy, as Aug-2009 is. In that case:

=if(A1 = date(year(A2),month(A2),1), "same...", "not same...")
