It's Star Wars Day! Whether you're celebrating the 20th anniversary of "Revenge of the Sith" or just adore Baby Yoda, here's how to mark May the 4th.

Star Wars Day is a day that has evolved into a universal celebration of the film's world, and everything in it.

Star Wars Day is an unofficial holiday celebrated every year on May 4 — as in, "May the 4th" (as in, "May the Force be with you"). And every year, we see retailers release limited-time discounts and product launches in honor of the geeky occasion.
