Predictions that a major world transition
to happen on 2012-DEC-21.
This web site lists many dozens of prophecies that
predicted the end of the world would occur at various dates in our past. They have one factor in common: all of them have totally failed. This perfect record continued on 2012-DEC-21 with the failure of a prediction based on the rollover of the Mayan calendar at the 2012 Winter Solstice on DEC-21.
The ancient Mayan's and their modern descendents considered this date as the ending of one approximately 5 millennia-long calendar interval, and the start of the next. Its significans was comparable to a New Yorker taking down the previous year calendar on JAN-01 and putting up a fresh calendar for the new year.
Many western authors and webmasters reached a much more pessimistic prediction; they expected some form of doomsday for humanity, or for all life on Earth, or even for the Earth itself. Other authors were more optimistic; they predicted some form of positive spiritual transition on that date.
Negative expectations for the day were held in advance by about 1 in 4 American adults, and about 1 in 10 persons worldwide.
We expect that some authors will cook up a new doomsday date, at some time during the 2020's, and start beating the drums in the near future for a new Armageddon. Sadly, an author without ethics can make a lot of money scaring the wits out of people.
