End of the world man.
Don't think the world will end in 2012. It is simply the start of a new cycle. Many have been fooled into believing that some how the Mayan calender comes to an end after 5125 years but this is completely false. Just as our calender ends on December 31st their calender also has cycles. It is more complex but in essence it just starts over as ours does on Jan 1.
They measured long time periods by means of a Long Count, in which one 360-day year (a "Tun"), consists of 18 x 20-day "months" ("Uinals"). Twenty of these Tuns is a Katun; 20 Katuns is a Baktun (nearly 400 years); and 13 Baktuns adds up to a "Great Cycle" of 1,872,000 days, ( 5200 Tuns, or about 5125 years).
There has been a great effort to correlate the Mayan calander to the Gregorian calender since 1905. Correlation # 584283", this was finalized in 1950, and puts the start of the Great Cycle ( day 0.0.0.0.0) on 11th August 3114 BC, and the end-date (known as 184.108.40.206.0.) as 21st December 2012.
No one knows when the end will come because it is in the future. Only the past can be written.
Don't cash in your 401k and blow it based on some crazy prediction. Nothing will happen except for mass hysteria due to idiots believing that the world is going to end.
