I have a worksheet with two columns, each column has a date/time value. I need to know how many of the cells in column A match the cells in column B on a row-by-row basis. Now, I could do it row by row with IF, but is there a way to look at the whole range and just count in one instance?

To clarify, the same values must only take place in the same row (e.g., A3=B3), and I'd like for the formula to return how many of those cells equal each other. Thanks!

try:

=SUMPRODUCT(N(A1:A20=B1:B20))

Thank you so much, Claus. I know I'm pushing my luck and the bounds of courtesy here, but is there a way to make them count the entire column range (eg. A:A and B:B) avoiding blanks?
