Count number of times a date is over 3 years in a column

I need a formula to count the number of times a date in a column is over 3 years from the current date.

Example is attached. I am using Excel 2003, Thanks so much. dcoates

Try this formula

=COUNTIF(B5:B100,"<"&DATE(YEAR(B2)-3,MONTH(B2),DAY(B2)))

Using your posted workbook, this regular formula returns the count
of instances where the "Date Training" is more than 3 years ago:
=COUNTIF(B5:B18,"<"&EDATE(TODAY(),-36))

In your example, the formula returns: 1 (2008-08-20 is more than 3 years prior to today)

Does that help?
