12/21/2012 is the day everyone says that the world will end because it was predicted by nostradamus and its the end of the mayan calendar. Some strongly believe in this, while others do not.

IF YOU BELIEVE IN THIS THEN BE PREPARED TO DIE. BUT IM GONNA LIVE MY LIFE HAPPILY INSTEAD OF BEING SCARED OF SOMETHING THATS NOT GONNA HAPPEN. JUST STATING MY OPINION.

On this day people will have major freak outs while the smart people of the world are all out having fun while the world record of suicides is reached on then day of the phony apocalypse.

Really, is the ending of this era, described by the mayan civilization, and it has 7 pre steps in which all the humanity will experiment. In the steps are included i.e. the earth's pole shift and global warming and other interesting stuff.
12/21/2012, it's the end of our era started at 3014 b.C. spelling 21/12/2012 too.
