"May the Force be with you" is the most quoted phrase from the "Star Wars" series of George Lucas .

The series started in 1977 and there have been numerous sequels after that, with the last one released in 2017. The Star Wars series has millions of fans around the world.

At some stage someone made a joke and changed the quoted phrase to "May the Forth be with you," and fans around the world started to celebrate May the 4th as the Star Wars Day. The date was later adopted by the franchise and is now the official International Star Wars Day. This is the only movie series with an official day.

World Health Day is on April 7th, the Mexican victory over the French is celebrated on May 5th and the International Workers' Day is on May 1st.
