The date of 21 May 2011 is from a site which explains that the earth will be exactly 13,000 years old and on that very exact day GOD closed the door behind Noah. What they say is that JESUS  said as in the days of Noah..... Also I see that they changed their opening page to TRUMPETS BLOWING.  They are very CERTAIN that that will be the day of the LORD as well as the Rapture,  I think.  As I can make out that JESUS said nobody knows the day and the hour is just that it all revolves around the sliver of the new moon reported by 2 or three witnessess and then the trumpets start blasting.... Love in CHRIST,    Leigh.      robertcross660@yahoo.com
