May the Fourth be with you. Star Wars Day

May the Fourth be with you! The 'Star Wars' universe has captured the imagination of fans for decades and its impact, like the 'Force,' is all around us. The original 1977 film introduced us to a galaxy far, far away, a cast of unforgettable characters, and a gripping battle between good and evil. Its reach has since extended to television, books, comics, theme parks, thousands of products, and a day of its own to celebrate the much-loved sci-fi franchise.

Fans might recognize today's image of the Mayan ruins in Tikal, Guatemala, as the rebel base on Yavin 4 from 'Star Wars: A New Hope.' These real-life temples served as a key setting in the cinematic Battle of Yavin, a fight so pivotal in the 'Star Wars' storyline that calendar years in the universe are called ABY or BBY: After the Battle of Yavin or Before the Battle of Yavin.
