If we cosider vaha kai as a mark at the end of 28 periods with 13 days in each, then the meaning probably is connected with how in a month the light shining on Moon will disappear after 28 nights. Beyond vaha kai in Gb5-10 there will be days comparable to the 29th night in a month, it will be a time without light.

There are 31 kiore-henua-maro periods on side a of G, which suggests we should count on beyond 28 * 13 = 364. Saturn, the dark one, is located in the first of the nights without light:

	362			37
Gb8-30 (1)		Gb5-10	Gb5-11 (365)		Gb6-20 (403)
28 * 13 = 364			3 * 13 = 39
31 * 13 = 403

The extraordinary Moon day glyph Gb6-20 obviously must be important, and we now can see the reason why it was designed to be eye-catching - it stands at the end of a measure for the 'year'.

The following glyphs (cfr at haú ke) could be dark nights for 'binding', for instance referring to the 4 quarters:

Light (the 'feather' signs) is left, at the back. 21 in Gb6-21 is beyond the limit set at 20 by Moon. The structure beyond vaha kai will then be:

	37
Gb5-11 (365)		Gb6-20 (403)	Gb6-21	Gb6-22	Gb6-23	Gb6-24
3 * 13 = 39			4 extra glyphs

	76
Gb6-25 (408)		Gb8-30 (472)
5 * 13 = 65

5 in 5 * 13 = 65 surely refers to the new light fetched from Saturn, who needs 'one more' night to add to his odd number 39. Also Gb6-25 should belong to him. 25 = 5 * 5 confirms this glyph as a glyph of Saturn.

In view of all this, it is doubtful if 8 * 13 = 104 days at the beginning of side a really can represent Waning Moon. A better choice would be to say that they correspond to waxing light. Time makes a 'jump' beyond 13 * 31 = 403 days, and during these dark nights - in the darkest of times before Sun will be seen moving again - the mystic regeneration of 'fire' in the sky takes place.

Rogo in Gb6-26 presumably marks the end of winter solstice, and 14 * 29.5 = 413 (probably corresponding to the kuhane station Tama) is where a new Moon cycle should begin:
