Harold Camping, president of Family Stations Inc., apologized for his wrong May 21 Doomsday prediction but is sticking to his guns, now insisting the real Judgment day to be on October 21, 2011.

Harold Camping called the event last Saturday an "invisible judgment" and that something did occur - something "spiritual," not "physical." He added that the actual Apocalypse will now occur five months after May 21 which is on October 21st.

On the "real" Judgment day, a fireball will said to consume the earth and 200 million Christians will be carried up to heaven, according to Camping.

The 89 year-old retired engineer spent millions on more than 5,000 billboards and print ads worldwide to spread his May 21 Rapture prediction. A good portion of it said to have come from donations from his followers.

Through a book published in 1992, Camping previously predicted the Judgment Day to be happening in 1994. Justifying his first wrong prediction, he reportedly said "important subsequent biblical information was not yet known and there may be something he overlooked."

May 21, 2011 is Judgment Day! That's what 2,000 billboards around the world and various ads in the internet are saying.

For months now, Harold Camping and the members of his Christian ministry called Family Radio, spread the word through the billboards and ads about the Judgment Day which they say will start later today, May 21st.

Camping, an 89 year-old retired civil engineer, believes that based on the clues in the Bible and applying some mathematical computation, May 21, 2011, is the beginning of the end for Earth.

According to Time, Camping cited two Bible passages in determining the date. The first one is the book of Peter which implies that the end of the world will occur 7,000 years from the date of the Great Flood. The other one is the book of Genesis which says the flood occurred on the "17th day of the second month." Taking a look at the Biblical calendar of our day, May 21, 2011 is the corresponding date.

So what will happen on May 21st? Camping predicts the following:

On May 21, 2011 two events will occur. These events could not be more opposite in nature, the one more wonderful than can be imagined; the other more horrific than can be imagined.

A great earthquake will occur the Bible describes it as "such as was not since men were upon the earth, so mighty an earthquake, and so great." This earthquake will be so powerful it will throw open all graves.The remains of the all the believers who have ever lived will be instantly transformed into glorified spiritual bodies to be forever with God.

On the other hand the bodies of all unsaved people will be thrown out upon the ground to be shamed. The inhabitants who survive this terrible earthquake will exist in a world of horror and chaos beyond description.

Each day people will die until October 21, 2011 when God will completely destroy this earth and its surviving inhabitants.

Do you believe this? And are you ready for Doomsday?
