I think it's easier to use Date#leap? for this question.

puts 'Starting year:'
start = gets.chop
puts 'Ending year:'
ending = gets.chop
if start.to_i > ending.to_i
  puts 'Ending year should be bigger than staring year'
else
   puts 'Leap year between ' + start + ' and '+ ending + ' as below:'
   while start.to_i <= ending.to_i
    if Date.new(start.to_i).leap?
      puts start
    end
    start = start.to_i + 1
  end
end
puts 'all done'
