The Star Wars Day comes from a publication in the British newspaper London Evening News of May 4, 1979. It was a note in which members of the Conservative Party of the United Kingdom congratulated Margaret Thatcher for her newly acquired position as Prime Minister of the country. "May the 4th Be With You, Maggie. Congratulations ", said the letter that gave rise to a play on words that said" May the force be with you "
The fanatics of start wars have now taken this play on words and born this celebration, why not join this celebration with a good marathon to see the whole saga?
