X-Day is observed on July 05, 2023. X-Day is a traditional part of the Church of the SubGenius, a religion formed as a parody of cults and extreme religious groups, and their pamphlets and claims. X-Day fell on July 5, 1998, the scheduled "end of the world", and has been celebrated on July 5 each year since then. From its inception in 1980, the Church had prophesied that an army of alien invaders (known as the "X-ists" or "Men From Planet X") would land on the planet Earth and destroy the world of "normals", "pinks", and "glorps," while the members of the Church of the SubGenius would be rescued by the aliens and taken away into space.
Regular events at X-Day include a symbolic effigy burning of J.R. "Bob" Dobbs (the founder of the Church of the SubGenius); a baptism where participants have their sins "washed away", "and receive new ones in return"; concerts and performances by underground rock bands and performance artists, such as The Amino Acids; theme camps; and an auction where participants are encouraged to donate strange, unusual, and offensive items of all sorts (including themselves).
