Calculating day differences between two cells

For example:
On cell A1 01/01/2011
On cell B1 01/04/2011
On cell C1 it should display "Less" if day difference is less than 90 days otherwise it should display "More"
Thanks in Advance!

How about :- =B1-A1

How about :-
=B1-A1

it worked.

=IF(B1-A1<=90,"LESS","MORE")
