Season chart using hashes

Question

seasons = { [20,"March"] => spring, [20,"June"] => summer, [20,"September"] => autumn, [20,"December"] => winter }

for example spring starts from 20 March etc

can someone make a code to display current season on the screen using above hashes and send it to me for e.g today is 4th jul and it is in summer. that will make a great example for this lesson
