Solar time
The more advanced the culture, the better the calendar system. Even by modern
standards however, cycles that last roughly 26,000 years are too long to gather
meaning from or even to measure accurately.
So the Maya developed something called the long count. This is a circular measure of time and is equivalent to 5125.36 years in the Gregorian calendar. At the end of this cycle humanity reaches the next stage in development. It is a specific count that can be measured precisely.
The Maya developed this astonishing degree of accuracy by looking INWARDS, not outwards. Using substances like ayahuasca, the high priests were able to record the pulse of the universe across time spans too fantastic to have any seasonal relevance.
For confirmation of what they were shown, they then looked to the stars.
The Maya began their long count on what they referred to as the Birth of Venus. Their Tzolkin calendar placed the cycles of Venus in a central role in the measurement of time. The 104 year Venus Round cycle was an important ceremonial event.
Venus and Earth have a phase-locked orbital cycle that is based on a 13:8 ratio. This is because Venus revolves around the sun 1.618 times faster than Earth so that 13 Venus revolutions is equal to 8 Earth years. By establishing Venus as the key component of the sacred calendar the Maya automatically built the golden ratio into their system.
Numerologically, the Maya worked with base 13 and their calendar system reflected
these multiples: 13, 26, 39, 52, 65, 78, 91, 104 and so on. As an example,
each of Earth's seasons is 91 days or 13 weeks long, which gives us a year
of 52 weeks—half a year is 26 weeks. They also understood the vital
multiples of 13 which included 13,000 and 26,000. The five suns, each lasting
5,125.36 years, add up to the Great Zodiacal Year.
13,000 years is a very important time period because it measures the time between ice ages. But what it really shows is the periodicity of our solar output cycle: there are short and long term fluctuations in solar energy and as a result there are great ice ages, little ice ages and warm inter-glacials (which we are in nearing the end of now).
Currently our sun is overheated and so is the Earth. The result is planetary instability manifested in earthquakes, volcanic eruptions and extreme weather patterns.
The Maya knew that the Venus Transit acted like a circuit breaker—switching off the sunspot cycle and impacting the Sun-Earth-Venus system. This happened prior to our previous two little ice ages that were characterised by periods of diminished solar activity.
The Venus Transit will signify the demise of the fifth sun and trigger the next cycle, the sixth sun. It will culminate in the galactic alignment and start the precessional cycle anew.
And what modern year equates to the Mayan end of the world in 13.0.0.0.0?
Well, 2012 AD.
