Ok, let's try this array formula**.

Assumes there are no text entries in the range. This version does not
depend
on the dates in the column headers.

=MAX((A2:Q20)*COLUMN(A2:Q2))-MIN(IF(A2:Q20,COLUMN(A2:Q2)))+(COUNTIF(A2:Q2,"0" )0)

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the
SHIFT
key then hit ENTER.

Thank you! That is awesome!! But I have one other ? What if my date
headers
extend from Jan-08 to Feb-09? If I use the formula and adjust the range
for
the 14 Mo. range, there are negative values returned for rows with data
in
the Jan-09 or Feb-09 columns. Is there a way to adjust the formula to
work
for more than 12 month range? Thanks!

Assume your date headers are in the range A1:L1 (Jan to Dec dates)

Data in row 2 on down.

Entered in M2 and copied down as needed:

=MONTH(LOOKUP(1E100,1/A2:L2,A$1:L$1))-MATCH(TRUE,INDEX(A2:L20,0),0)+1

If there are no numbers 0 then the formula returns #N/A

Yes, the numbers will always be positve. And yes, the header dates
are
true
Excel numbers (i.e. Jan-08 = 1/1/08)

Thanks and look fed to your response!

Cleaned up the example

That's much better!

Ok, are the numbers in the range *always* positive numbers?

Are the dates in your headers true Excel dates?

I'm looking for a formula that will Count the # of months of the
duration
of
a project (row). In this example, I want a formula to calculate
the #
of
months from beg to end months. This example below (Row 2) is
assuming
the
project started in JAN and ended in Jun. So the result should be
6
months. So
I want to count the months with zeroes in between the beg and
end
months.
In
my spreadsheet, I have columns going out to Dec-08. So there are
0's
in
every
month after Jun in Row 2 in my spreadsheet. Is there COUNT or
maybe
a
SUMPRODUCT formula that will achieve this? Thanks!!
