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?

The Rapture is defined by Wikipedia as a "reference to the being caught up of 1 Thessalonians 4:17 when in the end times Christians will be gathered together in the air to meet Christ." In short, it's Doomsday!

If Mayans believe that the end of the world will be in 2012, a Christian radio network is convinced that it would be sooner. How soon? Just less than a week from now - on Saturday, May 21, 2011.

For months now, the Christian ministry Family Radio has spread the word about the impending Judgment Day on May 21.

How did they come up with the date?

According to a Time.com article, the Ministry "cites two Bible passages to determine the date. - the book of Peter implies that the end of the world will occur 7,000 years from the date of the Great Flood and the book of Genesis says the flood occurred on the "17th day of the second month." Taking a look at the Jewish calendar, the de facto datebook in that era, May 21, 2011 is the corresponding date. Family Radio predicts great earthquakes will shake the Earth at 6 p.m. on the 21st, continuing for five months."

Do you think the apocalypse will be on May 21? Are you ready?
