The Sacred Geometry of Sacred Time
in the Olympiad and the Mayan Calendar Round (cont.)
By William Glyn-Jones

The Great Zodiac Cycle

The Great Cycle of the Zodiac ages takes around 26,000 years. 20 x 13 = 260, and 2000 x 13 = 26,000 - that's 2000 years for each of the 13 Zodiac ages (including the Serpent Bearer). We can also integrate this with the Venus cycle, by dividing the 2000 by 8 to get 250, and then observing that 250 x 104 = 26,000. In other words, in loose, conceptual terms, we can say there are 250 Double Calendar Rounds or "Venus Squares" in the great Zodiac Cycle.

To divide up the 26,000-year cycle into 13 sections in this way, we need to decide on a starting place. The convenient consensus is the same solstice of Winter 2012/2013 to be taken as the start of a 2000 year Long Age of Aquarius, since there we have the coincidence of the end of the Mayan Long Count and the close conjunction of the Sun and the Time Portal of the Black Hole.

Making the Venus Cycle Work For Us

It will not serve us to be twiddling our thumbs too much when using a calendar of Sacred Time. The purpose of it is not to set aside distant days as special, but to enrich our sense of time as a whole. It's not all about 2012. What about today? We can employ geometry to understand the connection to the bigger pattern, and then the days that are thus picked out have an aura that extends around them, a pre- and afterglow, just as you don't need to be standing on top of a temple to appreciate the beauty of its architecture, but can enjoy the view even from a distance.

Key dates we have identified so far are the start of each 8-year Pythiad, such as early June 2004, 2012 and 2020, and the intervening half-Pythiads or Olympiads, such as early June 2008, 2016 and 2024.

What other dates can we pick out? The 5th year of the 8-year Pythiad will include a Golden Section of the Pythiad. The Fibonacci series homes in on this. 5/8 gives a rough approximation, giving for example early June 2009 and 2017 as key dates. We can also measure backwards through each Pythiad, (3/8), giving June 2007 and 2015.

8/13 homes in closer to the Golden Section, i.e. the completion of the 8th Venus year after the start of the Pythiad, since there are 13 in the full cycle. This occurs one Moon cycle earlier, in early-mid May, 2009 and 2017 (and later for 2007 and 2015).

The Venus synod retrograde movements also occur at geometric intervals of the period, namely 1/5th of the full 8 years. So for example March 27th 2009 was a Venus-Sun conjunction in the middle of a synod, and in fact this is yet another part of that Fibonacci series, being 3/5 of the way through the period. 3:5, 5:8, 8:13. The conjunction in the middle of the next Synod is on 7 October 2010. (A more complete list can be seen on Wikipedia under "Aspects of Venus".)

We've halved the period, we've looked at its Golden Section, and we've divided it into 5ths. What other dates can we consider? We have available to us the option of following the 13-day and 20-day cycles of the Tzolkin since we know this integrates with this same Venus cycle. The Tzolkin count has been kept down to the present by daykeepers in the Guatemalan highlands since the times of the Classic Maya, and you can find a Tzolkin date using an online converter such as

But I don't want to leave it there. Since we have seen the Tzolkin integrating with the Venus Cycle, we could chose to count out the 13 and the 20 in such a way that the start day of the Venus Pythiad (e.g. June 6, 2012) is also a 1,1 day in the 13 & 20 count, thus revealing the Olympian Calendar Round. This is not intended as a replacement to the Mayan round itself of course, but as an additional count calibrated to the Venus cycle and appropriate to the "Western Tradition". The coincidences beg us to establish this new count because as we have seen a double calendar round of 104 years joins the London Olympics summers of 1908 and Venus transit year 2012!

In fact, we know from the Dresden Codex that in the earlier period the Mayan count was periodically adjusted so that at a key date in the 104-year "Venus Round" the first rise of Venus as a morning "star" would occur on a 1 Ahua day of the 260-day Tzolkin. Ahua is actually the 20th or last day in the 20-day cycle. The significance of timing this to the first rise of Venus must have been due to some specifically Mayan association. It makes more sense for our Olympian Round to just use the number 1. Also, if we go by the transit day June 6 2012 (rather than the First Rise of Venus day three days later) the 13-day cycle happens to coincide with the traditional Mayan count, because 6 June 2012 falls on a 1 of 13 day, and anyway it is now the transit day that has become more significant, as it is now easily observable. Therefore, June 6 2012 can be 1,1 (i.e 1/13, 1/20) in the a Tzolkin of the Olympian Calendar Round, and the rest is extrapolated from there. And there is an easy conversion process. For a particular day, find the Mayan Tzolkin day (e.g. at the website address given above), and then subtract one from the number in the 20-day cycle. Eg. Ik (2), becomes 1; 1 (Imix) becomes 20; 20 (Ahua) becomes 19, and so on. Easy. I've tried following this pattern by stringing beads on a necklace for the 13 and 20 day cycles, but this didn't give me a feel for the bigger pattern. More effective I think is marking off the days on a table of 13 columns and 20 rows snaking down each column of twenty but counting in 13's. That way we can see at a glance how far we are through the Tzolkin. An example here shows the 260-day "Olympian" Tzolkin in progress during the writing of this piece, with a cross indicating the day in which this sentence is being penned. Further Olympian Tzolkin tablets will be posted to my website at
