Winter is longer south of the equator than in Maya-land, which could explain the change from 80 to 84.

... The orbit of the earth around the sun is not a circle but an ellips and north of the equator 'summer' is longer (at present) than 'winter', while the opposite rule governs the seasons south of the equator. Consulting my almanac for 2004 I find that 'summer' has 186 days, while 'winter' has 180 days. The exact period varies between the years because the calendar counts in whole days ...

I have here cited myself, as I once wrote and documented in Index (while discussing the number of double sun-signs in the skirt of Pachamama):

... In spite of the knowledge of the year's true length (ca 365,25 days) the people by the lake of Titicaca decided to use a Sacred Year with only 354 days. That is the result I arrive at after having analyzed the skirt around Pachamama. All the sun-signs are visible, at least partly. None is totally obliterated. Posnansky, though, arrived at 364 days, a number I cannot endorse. I can see 94 ('winter') + 83 ('summer') = 177 double sun-signs on the skirt, and 2 * 177 = 354. Furthermore: the visual harmony of the skirt cannot tolerate as many as 364 ...

It ought to be added that 354 = 6 * 59, six lunar double-months.

If once 200 days was decided as the correct number of days for summer, shifting the number to 192 is a rather good correction for moving from say Maya-land to Easter Island. I found an approximate number to be 6 days from consulting my 2004 almanac. The Titicaca people judged the difference to be ca 11 days. 200 - 192 = 8 is at least as good, because 8 is the perfect number.

Gates:

"... the Maya astronomers knew the fractional errors connected with his period figures and corrected them by larger multiplications and intercalations. Returning now to our glyph-forms 1.1n etc [variants of Imix].

The ephemeris carries along accurate correlations of lunations and solar eclipses; at the end of the eclipse term, one of these ends on 10 Cimi, the other on 12 Lamat, shown by the upper and lower rows of day-signs. Above the thirteen red thirteens on page 51 we find our gl. 1.1n, stating '2 days are needed to tie up', from 10 Cimi, to the end of 46 tzolkins, on 12 Lamat ..."

In other words: One of the uses for Imix was evidently to 'tie up' the effects of fractions. Down in the water it is murky and the fractions belong there, I imagine.

Most interesting: I have earlier used much effort in trying to fit the mago of Ka4-14 into the pattern involving a high summer season with 52 glyphs. Once, for instance, I was very close to the Imix correction of fraction method:

Beyond spring, midsummer, and autumn equinox, sun will be rapidly waning, leaving for Hiva. The open feet sign in Ka3-3 seems to indicate his last stage: Ka3-1 Ka3-2 Ka3-3 Ka3-3 would then be a further determinant of the 'sun-fish' in Ka3-1 - its last 'spiritual' stage. The strange sign at the back (tu'a) of the sitting person suggests the season when we no longer can see the 'face' of the sun. In period 20 (twice 10 and 14 beyond 6) we can read about the point when sun is turning around (leaving us in the dark): 20 Kb2-107 Kb2-108 Kb2-109 Kb2-110 *Kb2-12 *Kb2-13 *Kb2-14 *Kb2-15 Kb2-110 indicates the final of the sun's presence by the maro sign at right. The henua sign (in the middle of the glyph) is similar to the one in Ka4-15: 6 Ka4-13 Ka4-14 Ka4-15 *Kb2-14 is number 73 of the glyphs in the calendar, 52 beyond Ka4-14. 365 / 5 = 73, and 52 * 7 = 364.

Is the calendar meant to be used in several different ways? Counting can be done e.g. from Ka4-15 up to and including Kb2-14 with one week for each glyph, meaning (it seems) that a whole year (52 * 7 = 364) will be covered. Though then the rest of the glyphs in the calender will not be used: Ka4-14 is number 21 in the calendar, i.e. 3 weeks would then lie before the year cycle, beginning with Ka4-15 and stretching up to and including *Kb2-14. Beyond *Kb2-14, beginning with *Kb2-15, the pictures in the glyphs tell us to move up to and including the last glyph in period 29, Kb4-14. The line number and ordinal number in the line also tells us to do so (similar to Ka4-14): 29 14 connects to Ka4-14 and to Kb2-14 Kb4-10 Kb4-11 Kb4-12 Kb4-13 Kb4-14 30 A different type of period. Kb4-15 Kb4-16 Kb4-17 Kb4-18 31 ... A new season arrives. Kb4-19 Kb5-101 Kb5-102 32 Kb5-103 Kb5-104 Kb5-105 0 A new fire is generated. Ka3-13 Ka3-14 If we count 52 - 21 (the glyphs at the beginning of the calendar up to and including mago in Ka4-14) = 31 glyphs from *Kb2-15 we will reach henua ora in Kb4-12 (which is number 104 + 1 in the calendar) ... Counting 52 for half a year must imply that each day is divided into two parts (night and day). In the calendar the summer half of the year needs 52 * 7 = 364 halfdays = 182 days = 26 weeks. Likewise the winter half of the calendar has 26 weeks. The 3 glyphs at the end of period 29 (Kb4-12--14) perhaps represent the difference between 365¼ and 364. 3 glyphs equals 1½ days.

Vinapu (down in the 'water') is the place where all the people 'from the homeland' gathered at the end of the year because they must give feathers (maro) to the island king, thereby making him take fire again.

South of the equator winter solstice lies in the south, not as in Maya-land up close to the North Star:

19 Vayeb	glyph type 74, used as final in tzolkins	75 God of the north

"... almost if not quite the most important deities in the Maya ritual were the Four Chacs, the Pauah-tun, ruling the four quarters and colors. It is their cult that goes through the chants from first to last, with the colors and offerings, and with Itzamná and his consort Ixchel as the great superior, beneficient deities. Both the Chacs and Itzamná ruled the Quarters, He through them; He was the God, they the Guardians, and either could be called Red Lord, White Lord, etc.

In most mythologies the East and North are the sacred quarters; in one of the chants Itzamná is called U yum ki chac ahau Itzamna, 'Father of the Sun, Great Lord Itzamná', repeating one of the traditions which represents Kin-ich-ahau as the son of Itzamná.

So that we not only have 'the Lord Sun, the East', on the authority both of the glyphs and the texts, but also (on the strength of our glyph 71.1 or 75.1) 'The Lord' among the Chacs, for the North - and of course its Star." (Gates)

North Star is the father of the sun baby rising in the east. At least north of the equator. Maybe it is the North Star which is rising (being born) in Pax?
