Once again. The vai glyphs ought to define the rainy season:

	289		34		2		4
*Qa2-32 (55)		Qa9-3 (345)		Qa9-38 (380)		Qa9-41 (383)
290		36			7
333

133			214	54
	*Qb3-37 (521)	*Qb3-38
135			268
403

But *Qa2-32 should be the last glyph of this season, because then follows a great gap in time to next similar vai:

*Qa2-32	*Qa4-23	Qa8-47	Qa9-3	Qa9-38	Qa9-41	*Qb3-38

The redmarked ones are special. In *Qa2-32 the straight vertical line of measure is at right - i.e. vai is at left, in the past.

36 + 7 + 134 = 177 = 6 * 29.5 and then there are 215 + 55 = 270 more to the end of vai.

	34		2		4	133
Qa9-3 (345)		Qa9-38		Qa9-41			*Qb3-37 (521)
36			7			134
177 = 6 * 29.5

	214	54
*Qb3-38 (522)			*Qa2-32
270

(177 + 270) / 2 = 223.5 days. Let us involve the remaining two glyphs:

74		211		2
	*Qa4-23 (130)		Qa8-47 (342)
286			3
289

177 + 270 + 289 = 736.

Qa8-47 is close to Qa9-3 and should therefore belong to that group:

	2		34		2		4	133
Qa8-47 (342)		Qa9-3		Qa9-38		Qa9-41			*Qb3-37 (521)
46								134
180 glyphs = 90 days

	214	54
*Qb3-38 (522)			*Qa2-32
270 glyphs = 135 days

74		211
	*Qa4-23 (130)
286 glyphs = 143 days

180 + 270 = 450 glyphs, or 225 (= 15 * 15) days.

Moon has a square of 15 days. And only 368 - 225 = 143 days are left to the sun. Zero occurs when the square of 12 is completed.

12 * 12 + 15 * 15 = 144 + 225 = 369 = 736 / 2 + 1.
