ABSTRACT
Doomsday is the Day of Judgment when Jesus will come again to judge the living and the dead, determining who will be saved and who will be damned. The events leading to the Christian doomsday are described in greatest and most authoritative detail in the Apocalypse. Doomsday is supposed to occur at the end of time after the sounding of seven trumpets, the appearance of seven signs, and the lifting of the seven seals of the closed book, which reveals the mysteries they concealed. Commentators on the Apocalypse have naturally been concerned to know the exact date of Doomsday. A few of the many well-known millennialist sects are the Shakers, the Mennonites, the Jehovah's Witnesses, the Mormons, and the Seventh-Day Adventists. The majority, though by no means all, of the predicted dates of Doomsday have been millennial. The "Y2K" phenomenon was a technologically imagined form of Doomsday.
