Various religious group are constantly predicting the end of the world. However, predictions for a few days over the next couple of years have gotten more press than most.
Saturday, May 21, 2011 is the nearest predicted date, and enough people have been convinced of it that some of them are paying for things like billboard space announcing it in the hopes of saving a few more souls before the end.
But why May 21? This date was computed by Harold Camping, who has a broadcasting network - Family Radio - through which he has spread the word. Like many Christians trying to compute the End of Days, he attempts to calculate the exact days of various Biblical events (May 21 is the 7000th anniversary of Noah's Flood, according to Camping) mixed in with some pretty hefty numerology and numerical symbolism.
