Is May 21 judgement day?

The billboards, mounted in Gaborone by Continental Outdoor Media for Family Stations Inc, a non-profit making organisation, started in 1958 by American citizen Harold Camping, give this succinct and bewildering message: "Judgement Day is Coming.  21 May 2011.  Cry Mightily unto God.  Jonah 3:8." The billboards, whose background pictures are of a mountain silhouette at sunset, with a person squatting at the foot of the mountain, goes on to show a terrestrial radio frequency and the times within which locals can access Family Radio.com, Family Stations Inc's radio station which can be accessed both online and via shortwave and a network of AM and FM stations.

According to Motlalepula Maxwell Moahloli, a Lesotho-based representative of Family Stations, inc., who was responsible for liaising with Continental Outdoor Media, Judgement Day will be a period of five months from May 21 to  October 21, 2011 in which "the entire world and universe will be burned with fire by Creator God".
