比较日期中的日期是否在今天的日期之前

Question

I have a date in the format of "4/26/2013". I want to see if that date is prior than the current year, whatever that current year may be (don't want to hardcode 2013) and count how many of the rows match that criteria. Say there are 6 rows of dates in that format:

=COUNTIF(C2:C7, YEAR(Today()))

This threw an error. I'm new to Excel, so I probably made a huge mistake! Can anyone see what is wrong with this?

Thanks!

Answer 1

If C2:C7 contain dates you need to compare them to the 1st of January in the current year, eg

=COUNTIF(C2:C7,"<"&DATE(YEAR(TODAY()),1,1))

or you can use SUMPRODUCT like this

=SUMPRODUCT((YEAR(C2:C7)<YEAR(TODAY()))*(C2:C7<>""))

Answer 2

I just figured it out. My syntax was wrong. The answer to the above example was:

=COUNTIF(C2:C7, ">"&YEAR(TODAY()))

That returned the number of dates in C2 - C7 that were prior to the current year.
