Suppose the 'flaring top' in Tzec and Pax are indicating 'birth':

The sun 'monkey' would then not have to leave at Pax.

"Two signs, Tzec and Pax, require the flaring open top, to distinguish them respectively from the chuen and the tun normal sign, on which they are formed. We at once get here the query: What is the relation of chuen and tun to Tzec and Pax, underlying this use? The answer should be partly calendric, perhaps partly historical." (Gates)

Is it possible to structure the 18 Maya months based on the birth of two different rulers, one in Tzec and one in Pax?

15 Moan could be illustrating the spirit of the sun, depicted as a falcon, flying away. 200 (10 months) of the tun year could 'belong' to the sun. Then could follow 80 days (4 months) until the tun year has ended.

'... The Pokoman used cah-vinak for 4 times 20, thereby expressing a qualitative difference associated with a multiple of 4. Otherwise they said k'al instead. Maybe Vinapu likewise is a special '4 times' (a multiple of 20)?'

Though number 84 obviously is a more probable length of such a '4 times' measure. 2 * 84 = 168 was also an important number on Easter Island. 360 - 168 = 192 = 6 * 32 = 12 * 16.

Each kuhane station could measure 16 days, and the distance from Hanga Takaure to Hanga Hoonu would then be 6 * 16 = 96 days, or half the full sun distance 192 days:

1st quarter		2nd quarter		3rd quarter		4th quarter
He Anakena (July)		Tagaroa uri (October)		Tua haro (January)		Vaitu nui (April)
Te Pei	Te Pou	Tama	One Tea	Mahatua	Taharoa	Nga Kope Ririva	Te Pu Mahore
Hora iti (August)		Ko Ruti (November)		Tehetu'upú (February)		Vaitu potu (May)
Hua Reva	Akahanga	Hanga Takaure	Poike	Hanga Hoonu	Rangi Meamea	Te Poko Uri	Te Manavai
Hora nui (September)		Ko Koró (December)		Tarahao (March)		He Maro (June)
Hatinga Te Kohe	Roto Iri Are	Pua Katiki	Maunga Teatea	Peke Tau O Hiti	Mauga Hau Epa	Te Kioe Uri	Te Piringa Aniva
84		96		96		84

On Easter Island 6 double-'months' in the sun (redmarked) could have been each 32 days long. 6 * 32 = 192. (Cfr 32 as the number of sun periods in G.)

The rest of the year would then have kuhane stations measuring only 14 night each. 6 double-'months' in the moon would each have 28 nights. 6 * 28 = 168.

192 + 168 = 360, a 'tun'. Or, once upon a time, a 'tun' was born in Pax and measured 168 nights.

192 is numerically related to 168 as 8 to 7. 8 * 24 = 192 and 7 * 24 = 168.

15 * 24 = 360, and 24 is the balanced measure of 32 and 28, given 15 (3 hands) as the pivotal point.
