"In Mexico and in Central America, quinary-vigesimal, decimal-vigesimal or pure vigesimal systems generally took 20 as the complete number. It was referred to by a word meaning 'a body' in Yaqui, 'a person' in Opata, 'a man' in Maya-Quiché and also in Arawak, so that the practice extended also to the northern regions of South America." (The Origin of Table Manners)

The calendars for the year in G and E have autumn equinox located in the 17th and 18th periods. In E the end glyphs of these two periods look nearly the same and differ from those in the earlier periods, showing signs of a gradual adaptation to later arriving end glyphs:

3
3	13	14	15	16	17	18

4
4	19	20	21	22	23	24

A major season (summer) has been counted up to its full 'body' (or 'person). The measure 20 for full is alluded to in the number of glyphs:

17
	Eb4-32	Eb4-33	Eb4-34	Eb4-35	Eb4-36	Eb4-37

	Eb4-38	Eb4-39	Eb4-40	Eb4-41	Eb4-42	Eb5-1
			*Eb5-2 is exactly as Eb5-4, a way to link the two periods. This variant of tagata* means summer. 14 glyphs in period 17 and 6 glyphs in period 18 result in 20 as the sum for the two periods. The measure is full.**
