May 4 is the 124th day of the year (125th in leap years). There are 241 days remaining. It is often known as "Star Wars Day," and the accompanying phrase "May the Fourth be with you" is a reference to the Star Wars phrase "May the Force be with you."
The phrase dates back to at least 1979, on the day Margaret Thatcher was elected the first female Prime Minister of the United Kingdom. Her party took out a newspaper ad in the London Evening News that said "May the Fourth be with you, Maggie. Congratulations."
On May 2nd, 2019, the state of California's legislature voted and officially declared May 4th as "Star Wars Day" in recognition of Star Wars: Galaxy's Edge opening later in the month of May.
