Hi again,

I still have a problem!!! In this list, with your formula, it returns 16
days. But the right answer is 14. Why? How can I have the right answer?

Try this (as I don't see your original post with the given formula):

=SUMPRODUCT((A7:A45<"")/COUNTIF(A7:A45,A7:A45&"")) where your data is
in the range A7:A45 -- adjust as needed.

Good Luck

Hi Barbara


Convert the date to the Excel number format by using format - number


Date Number Format =IF(A2-A10,1,0)

=SUM(c1:c 40) Gives 14.00

Hope it helps
