Econintersect:  California minister Harold Camping had called for 6 pm, May 21, 2011 to be the time at which judgement day would arrive.  He made the prediction in 1994 after his previous prediction for the end of the world at that time proved not to be true.  With a 15-year build-up, a relatively large furor was seen in recent months as the appointed day got closer.  According to the San Fransisco Chronicle, the date has been posted on 5,500 billboards across the U.S.  The billboards also advertise Reverend Campbell's radio broadcasts on Family Radio.  The day and hour were specifically identified as the start of The Rapture when Jesus Christ would return and the faithful would be swept up into the Kingdom of God.

The day and hour have now long since passed without any newsworthy events.  If the prediction was in fact not born out, it is not the first time that Armegeddon has failed to materialize when expected by prophets.  The site Armageddon Online.org has a list of more than 140 predictions of Armegeddon that have failed.

However, at least one source says that The Rapture did occur and was unnoticed.  If you are reading this, Judgement Day.com says you were not embraced by the Lord.  If all you know are still here, they also were not embraced.  It seems that Judgement Day believes that those that were saved on May 21 met their maker in a quiet and peaceful way not observed by the world at large.
