Yeah, but the fourth of May * does* exist and it’s commonly known as Star Wars Day
PS there's the classic non-apocryphal tale of George Lucas’ interview on German TV which he concludes by turning to the camera and saying “May the force be with you”, converted by the simultaneous translator to “Ich werde am 4. Mai bei Ihnen sein” - (“I”ll be with you on 4 May”)
True stories of this quality are rare and should be treasured...
