You may be getting pumped up for Cinco de Mayo, but the real party starts on May 4th, or Star Wars Day. While not an official holiday on the calendar, May 4th has become an adopted day of celebration for all things Star Wars- as in, May the Fourth be with you. The month of May also has particular relevance in the Star Wars universe. Six of the Star Wars films debuted in May and it’s also the month of George Lucas’ birthday (May 14th).
