Can you help me in finding difference of data between 12/10/2003 &
2/14/2009. With datedif or usual cell1 - cell2 formulae it shows 1893 days
where as my manual calculation shows it to be
Year Days

2004 360
2005 360
2006 360
2007 360
2008 360

Wow! This works great. I appreciate your quick responses when I submit a
problem I'm having. You always have a solution that works. I just wish I
understood what you did to make it happen. :-)

Try this:

E16 = start date
F16 = end date

=SUMPRODUCT(--(DAY(ROW(INDIRECT(E16&":"&F16)))=20))

That will count how many 20th of the months there are from a start date
to
an end date (inclusive).

I have tried this function but am having trouble with it returning the
right
value. I have an end-date of 1/20/2010 (in cell F16) and a start-date
of
2/11/2009 (in cell E16). I'm trying to calculate how many automatic
monthly
transfers there will be on the 20th of each month but the function is
returning a value of 11 when it should return a value of 12. The first
transfer will be 2/20/2009 and the last transfer will be 1/20/2010.a
total
of
12 transfers.

I hope that Dec 2008 - Jan 2006 is 35, rather than 23. :-)

An alternative to DATEDIF would be
=MONTH(A1)-MONTH(B1)+12*(YEAR(A1)-YEAR(B1))
Note that if you have different dates within the start and end months,
you'll get different results from the 2 formulae.
End of Jan to beginning of Feb gives a 1 month difference with the
original
=MONTH(A1)-MONTH(B1) and with my extension thereto, but DATEDIF counts
completed months (with various questions when months are of unequal
length).

That works when the two months are in the same year, but what if
they
are
in
different years? For example January 2008-September 2007 = -8, but
should
equal 4. Or December 2008-January 2006 = 11, but should equal 23.

Use the undocumented DATEDIF function:

=DATEDIF(B1,A1,"m")

(The first date must be the earlier date).


See http://www.cpearson.com/Excel/datedif.aspx for documentation.
