Because you are trying to use the RIGHT function (which is designed to
manipulate a string) with a value; in Excel 4/23/08 is equal to 39561
because it is counting the number of days since 1/1/1900.

Try using YEAR instead of RIGHT:
=IF(YEAR(D14)=2008,true,false)

In D14 I enter 04/23/2008
in D15 the formula contains
=IF(RIGHT(D14,2)="08","true_value","false_value")

Why is D15 returning "false_value"?
I'd expect "true_value"

Thanks for your help.
