May 4 is informally known as "Star Wars Day" to fans of the sci-fi film franchise. Why May 4?
The answer is as simple as a bad pun. May the 4th was adopted by fans simply because of the resemblance to the movies' famous catchphrase, "May the force be with you."
The "holiday" is relatively new.
The first organized "Star Wars Day" celebration happened in 2011 on May 4.
