May The 4th ( May the Force ) has become known as "Star Wars Day" to fans around the world. We here at TheForce.net hope you enjoy the day however you choose to celebrate!
Additional History (Wikipedia) The date was chosen for the pun on the catchphrase "May the Force be with you" as "May the Fourth be with you". Even though the holiday was not actually created or declared by Lucasfilm, many Star Wars fans across the world have chosen to celebrate the holiday. It has since been embraced by Lucasfilm as an annual celebration of Star Wars.
Apocryphally, the reference was first used on May 4, 1979, the day Margaret Thatcher took office as Prime Minister of the United Kingdom. An online news article from the Danish public broadcaster says her political party, the Conservatives, placed a congratulatory advertisement in The London Evening News, saying "May the Fourth Be with You, Maggie. Congratulations."
The saying was used in a UK Parliament defence debate on May 4th 1994.
Astrophysicist and author Jeanne Cavelos used the saying on page 94 of her 1999 book The Science of Star Wars.
In 2008, the first Facebook groups appeared, celebrating Luke Skywalker Day, with the same catchphrase. While the initial group never received widespread acclaim, the phenomenon spread to college campuses a few years later, and Star Wars Day was born.
In 2011, the first organized celebration of Star Wars Day took place in Toronto, Ontario, Canada at the Toronto Underground Cinema. Produced by Sean Ward and Alice Quinn, festivities included an Original Trilogy Trivia Game Show; a costume contest with celebrity judges; and the web's best tribute films, mash-ups, parodies, and remixes on the big screen. The second annual edition took place on Friday, May 4, 2012.
Fans (even government officials) have celebrated Star Wars in a variety of ways in social media and on television.
Since 2013, The Walt Disney Company has officially observed the holiday with several Star Wars events and festivities at Disneyland and Walt Disney World. Disney had purchased Lucasfilm including the rights to Star Wars in late 2012.
Minor League baseball teams such as the Toledo Mud Hens and the Durham Bulls have worn special uniforms as part of Star Wars Day promotions.
