Example- How to do you display # of days between 6/11/2011 and 6/11/2012 and use only the month and day data (Year is not relevant). So If I used 6/11/99 I would get the same answer of days in between as 6/11/2011.

This is the formula I am using now, which gives me the data with the year information.

=IF(AND(A4<>"",A5<>""),DATEDIF(A4,A5,"0"),"")

A4 is start date
A5 is end date
