Past dates for failed doomsday prophecies

Here are some examples, with the predicted date of the end of all things. Please, past dates only, so we can share this with people who get easily scared of future dates.

1st century CE

 * Early Christianity: Second Coming. Any day now! In fact, within the lifetimes of Jesus's eyewitnesses.
 * Revelation: Armageddon. Indeed, the very word "Apocalypse" is the Greek word for revelation.

7th century

 * Muslims believed in the Qiyamah (Last Judgement) during which time Jesus will come to earth, end all wars, and kill ad-Dajjal &mdash; the Muslim anti-Christ. Then every person who ever lived will be bodily resurrected, before being judged by God. The faithful go to heaven, and the rest to hell. Apparently there's also room for some "People of the Book," i.e. Jews and Christians, though hopefully there won't be any wars between the lot in heaven. Presumably God will actually do something to stop fighting within his heavenly realm, unlike on Earth, so that celestial wars would seem unlikely.

16th century

 * Circa 1504: Painter Sandro Botticelli believed he was living during the End Times/, according to an inscription on his painting The Mystical Nativity.
 * 1533: Michael Stifel, Judgement Day. A common saying in German for PIDOOMA is to "calculate" or "talk a Stifel."

18th century

 * 1719: Jacob Bernoulli: a comet seen in 1680 would return and collide with the Earth. Said comet hasn't been seen since.

19th century

 * The "Great Disappointment": William Miller predicts the end would come in 1843... then 1844... oh. His many thousands of followers reacted in different ways to his utter failure: some wised up and gave up on his predictions, while others became Seventh Day Adventists. They're still waiting. Still others became the Jehovah's Witlesses, who badly retconned Miller's prediction so they could claim it actually did happen, just not the way he predicted.
 * 1865: predicted by Edward Bishop Elliott, a Victorian Biblical scholar; he later revised this to 1941.
 * 1881: according to an 1862 edition of the prophecies of Mother Shipton, who allegedly wrote "The world to an end shall come, In eighteen hundred and eighty one." (Seems she was no better at poetry than she was at prediction.)
