NO NO NO NO and NO. This 2012 is a long perpetuated myth that millions of Americans believe. It talks about it in
Zeitgeist - The Movie, but that movie just skims the surface of a few things.
First off, I study(ied) the ancient world, and real history, not text book lies. By constructing a timeline of events, you can make a line of when the planet Niribu has been close to earth. The Sumerians, and Egyptians both knew and glorified the planet Nibiru, Planet of the Crossing. This is represented by the Egyptian/Sumerian/Akkadian Cross, which is identical to the "Maltese Cross", and Christian crosses. It represents the planet of the crossing, a long with Egypt's winged disk which represents Nibiru.
To make a long story short, by using historial corroboration and not online myth, you can place the appearence of Nibiriu mathmatically somewhere around 2160, rouuggggly. However, since it's happened in the past and can happen again, you might beable to give or take some years due to celestial disruption in some way.
Seeeeeeeeeeeecond of all, the Mayans did predict the end of the world, but in many prophecies such as in the bible, word is never used. It should be AGE. The mayans predicted the end of the age, which is in line with the end of the Zodiacal age of Aquarius! To start off, I will explain how people arrive at the number 2012. The Mayans had 3 calendars in total, and revolved around a sacred 52 years which has more meaning but will not get into... The start of the long count calendar, is said to be August 3rd 3113 B.C. The Mayans also had different lengths of time, such as Pictun's Baktun's, Tun's, etc... The long count calendar, had 13 Baktuns( 13 baktuns = 1 great cycle ), with 144,000 days being in one Baktun
Now lets do some math. 144,000 days x 13 baktuns = 1,872,000 days = 1 Great Cycle
Take one great cycle, and divide by the length of time in a year, 365.25.
Now subtract the start of the Mayan calendar in years, 3113, to convert to our time.
You're now left with the year (2012.566).
However, one flaw exists with this theory. As stated by some author in the 1800's, insted of dividing the great cycle by the exact year, you must divide it by the mayan long count's calendar's perfect 360 which would result in the mathmatetically perfect 5200, and would align with mayan math. You then subtract the 3113 and then arive with 2087.
Now, to sum it all up, the mayans said it would be a spiritual / lighting / awakening, not any kind of end.
Cheers hope I explained everything well and taught someone something.
No worries about the end of the world, just worry about the people who will control you
