Probably lots of ways in lots of languages, but just for kicks (should 
be all on one line):

perl -MDate::Calc -e  "print 
Date::Calc::leap_year((localtime())[5]+1900)?'Leap year':'Not leap year'"

This uses the Date::Calc module in Perl which does loads of nice date 
calculations and manipulations.  You can install this with

yum install perl-Date-Calc

and then 'man Date::Calc' to see the documentation.
