The Mayan Calendar ends and restarts on December 21, 2012 (Winter Solstice). The calendar is exactly 25,625 years composed of five (5) cycles. Each of the five cycles is exactly 5,125 years. The last (current) of the five cycles ends on 21.12.2012 completing the whole cosmic cycle of 25,625 years! This is an amazing time we're living in! These Five Cycles are located in the middle of the Aztec / Mayan calendar. They are represented by four (4) symbols within the four central rectangles. The frame around the four rectangles (four cycles) represents the last 5th cycle (current cycle) giving it special significance. It signifies the fusion of the previous four cycles and the completion of the Great Cycle of 25,625 years. Our solar system travels in a backward sine wave motion through our galaxy - The Milky Way, known as the Cosmic Serpent to the Ancients. It's represented in the Aztec / Mayan Calendar (around its circumference) by two deities inside of serpents. Each time it passes the Galactic Plane of the Milky Way takes half of the 25,625 year cycle. Last time it passed was around 10,000BC - ending of the last Ice age. A full "S" sine wave is created when our solar system passes the Galactic Plane (Galactic Equator) twice. It completes the Great 25,625 year Cycle on December 21, 2012! The last (current) of the Five Cycles began in 3113 BC and ends (resets) on December 21, 2012. Thereafter, a new Great Cycle of five cycles begins starting from the First Cycle of 5,125 years. The Fifth Solar Cycle (current) of 5,125 years is called Caban in the Maya and Ollin in Aztec. It has multiple meanings including: consciousness, synchronicity, movement, shift, evolution, clue tracking, navigation, and earthquake. According to the Aztecs the fifth cycle ends in earthquake(s) - possibly a magnetic pole shift according to the latest scientific data, so let's be ready for the worst and hope for the best.
