Historically Doomed "Doomsday Dates"

The ultimate example of a set date which failed was of course Y2K or January 1, 2000. Many authors and ministries in 1999 were seriously committed to warning people that the end of the world as we know it (TEOTWAWKI) was nigh because of the year 2000 computer bug. Many people took them seriously and took action by stocking up on ready to eat (RTE) meal kits and other food supplies, investing in gold and silver, and preparing safe houses out of the city, etc. To their regret or relief, nothing happened.
