Pacal's Calendar

While reading Munro S. Edmonson's (1988) The Book of the Year: Middle American Calenderical Systems, I discovered several Mesoamerican calendar systems in which 1541 was actually 1522 (19 year units off). It appeared to me that with our complex trig-type mathematics, there was an extra 365 days somewhere within the modern Maya calendar calculations. The original1978 calculations are found here.

They are complicated and done with extreme care. However, they appear to add another 19 units to every year count.
In Mexico City, Even Bishop Noriega began to notice the historic was being manipulated, not only to the calendar system, but other information about the culture. Noriega's Carta de Despedida refers to the changes he witnessed during his term of office. If he noticed alterations during his century, what did scholars understand in the earlier centuries? Apparently, today our scholars are attempting to correct those manipulated documents.
The earliest manuscript I could find was in Rhetorica cristiana (1579), which was Valadéz's version of the calendar wheel system.

It was shown upside down as Figure 73 in the Handbook of the Middle American Indians (Vol. 14) with 18 elements in a smaller circle together with the five "dead" days noted. The eighteen units there referred to the nine Lords of the Night, and were matched to our months of the year in blocks on either side of the smaller circle.

Later, the Borgia Codex was studied at the Maya Seminar in March, 1997 at Austin. There I discovered that the 260-day calendar was augmented by 104 more days (the top and bottom borders), and those frames created a 364-day year.

This linear count shieft one day more (indicated by the tiny footprints) during its passage from one 260-day group to the next. The Valadéz Calendar was similar but it ran as a caracol instead of line to line.

When I saw the circle with the caracol, I started thinking about it. Since I could not run a caracol as a program, was it possible for a similar chart to be run as a list straight down. At least a straight line of two different calculations could be run together. My list only ran for 31280+ units. (If I wanted to reach the 80-year marker of Pacal, I had to add a set of 15,000 more units.) My count was created as two separate lists: one for 365-day and the other for 366-day counts.
One author, Lhuillier A. Ruiz, in his article (1977) "Gerontocracy at Palenque?" stated that Pacal had the skeletal remains of a 40 year old person, not an 80 year old. Although I did not reach Linda Schele's 80 years of age for Pacal (which was expected), I did manage either 55.56 years (through a 365 days a year) or 43.41 years (for a 366 day year which included Leap Years).

Chart for date possibilities

The G1 to G9 designation would be the 20 degrees each of the 360 circle plus 5 dead days (6 in leap year) as per the smaller circle above the main figure and should be considered as a calculation completely separated from the year count. We can relate this double calculation as a normal calendar (365.4 days of a year with an extra space of 5 degrees) run in conjunction with a horoscope (of a 260 degree span added to allow for nine constellations (Lords of the Night) of roughly 14 degrees each.) But it should not be included in the year count any more than our horoscope calculations shouldl.

These nine "gods" appeared to be nine constellations in the night skies, on either side of the world. If one uses this concept as the purpose of the G1 series, then the small notation of "Chip" Morris's comment in "A Temple Star Grid" found in the Archaeoastronomy section may be more important to us than supposed. He said that there was a periodic visit by the Maya elders at night to remove and replace the [same] roof tiles of a small building on his property. This need to open the roof tiles does not have any apparent purpose to a casual observer. With no reason forthcoming from the participants, one can suppose that because of a work schedule the Maya had no time during the day to do minor repairs to the roof undedr structure, or it was cooler during the night to do such work

However. if the above information is correct and the tiles were removed, but replaced as they had been, then it is more important for a more serious purpose. This casual roof inspection would be to check on the location constellations through the framework of the missing tiles on the roof. If they are not in the correct space, then their calendar must be adjusted.
That would indicate that all those "corrections" were in order to correct via the sky sightings during the year. Corrections to the calendar count only infers that the sky had shifted to a different seasonal position which the Maya guardians of the calendar designated as a correction. In this way the Maya arbitrarily kept up with the seasons and the leap year, with a minimum of the calendar.
The conclusion is that Pacal died during the ascension of a constellation (G-I) in the month of 6 Etznab on the day 11 Yax. This method makes more sense than an attempt to use higher mathematics which the natives never used.
