Yes. You read it right. Doomsday on December 21, 2012 is predicted. Doomsday refers to the end times, the day of the last judgement or of any final judgement. It is written in the bible on the Books of Revelations in which it foretells of an end time marked by a riotous series of events and a cataclysmic conflict between the forces of good and evil. For over centuries, the Book of Revelation has been the subject of much interpretation and debate.
