Matthias Stormberger: trying to get his birth and death dates for the 3rd Generation start of WWIII. Read that some put that puts the start date for WWIII at 1990 to 2010... which gets close to the 23 Dec 2012 date. (BTW his works were destroyed by the Nazis due to unfavorable predictions).

There is also at least one Jewish predection about when the Herald is seen again. The Herald is a star constellation that is supposed to be seen for the first time in thousands of years. Around September 2012 or 2013, I have not been able to find the exact date.

The Maya Calender I believe ends on 23 of Dec 2012.
The Winter Solstice is the 21 Dec 2012. at which time some say is the date the Sun aligns with part of the Cygnus Rift, a dark part of the Milky. Reading about, some say that there has been better alignments in the past, and on 2030 there is a better alignment. (hmm whos predictions says there will be great calamity followed by a time of piece then Bam the end of it all?, but I think they were talking astoroids..)

Looking in to it all but I belive that as the Mayan's Calender is a giant wheel, and that one complete cycle is about 26,000 years. Starting at one alignment at solstice with the (Galactic center?) and/or the Cygnus Rift to the next alignment. The wheel does not end but begains anew.

I believe the Hopi said there were other cycles before this one.

But with every new begining you have to watch for the birthing pains...
