Thanks for the pointers Eduardo!

The new code here works.
---------------------------------------

puts "Enter starting year:"
=C2=A0 =C2=A0 =C2=A0 =C2=A0 starting_year =3D gets.chomp.to_i
puts "Enter ending year:"
=C2=A0 =C2=A0 =C2=A0 ending_year =3D gets.chomp.to_i

year =3D starting_year
while true
=C2=A0 =C2=A0 =C2=A0 if year%4=3D=3D0
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 if year%100!=3D0 || year%400 =3D=3D0

=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 = =C2=A0 =C2=A0 puts year.to_s + ' is a Leap Year'
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 end
=C2=A0 =C2=A0 =C2=A0 end
=C2=A0 =C2=A0 year =3D year +1
=C2=A0 =C2=A0 =C2=A0 break if year >=3D ending_year
end

You can also use date s= tandard library for detecting leap year like this:

require 'date'

Date.leap?(1900) #=3D> false

Date.leap?(2000) #=3D> true
