The 'breaking of the bamboo staff' at 12 * 29.5 = 354 could be a development following upon the introduction of a system with 12 months. On the other hand, a double final of the year may be an ancient structure. The Maya indians also had a double final, judging from their two drum months (Pax and Vayeb):

5 Tzek	6 Xul	7 Yaxkin	8 Mol
9 Ch'en	10 Yax	11 Sac	12 Ceh
		10 * 20 = 200
13 Mac	14 Kankin
15 Moan	16 Pax	17 Kayab	18 Cumhu
	8 * 20 + 5 = 165
19 Vayeb
1 Pop	2 Uo	3 Zip	4 Zotz

Below are listed 6 * 6 = 36 glyphs:

Gb4-21 (28.5)	Gb4-22	Gb4-23	Gb4-24	Gb4-25	Gb4-26
Gb4-27 (29)	Gb4-28	Gb4-29	Gb4-30	Gb4-31	Gb4-32
Gb4-33 (29.5)	Gb5-1	Gb5-2	Gb5-3	Gb5-4	Gb5-5
Gb5-6 (30)	Gb5-7	Gb5-8	Gb5-9	Gb5-10	Gb5-11
Gb5-12 (30½)	Gb5-13	Gb5-14	Gb5-15	Gb5-16	Gb5-17
Gb5-18 (31)	Gb5-19	Gb5-20	Gb5-21	Gb5-22	Gb5-23

The extraordinary narrow and deep haga rave in Gb5-12 (day 366) must be a sign. The very last day of the solar year is not a whole day, only ca 0.25 of a day. Old myths all over the world tell about a kind of whirlpool or mill in the sky and in the middle of this whirlpool or 'millstone' there is a hole, through which people are drawn under. It would explain why there is only a quarter of a day at the end - the rest has gone down.

The swollen foot (in Gb5-12) is probably to be read as pau and the whole constellation as Hanga Te Pau, as has been suggested earlier (at haga rave). It must be emphasized that the same sign (hipu) is used at Hua Reva:

hipu	Gb2-27 (283)	Gb4-17 (338)	Gb5-12 (366)
	84 = 3 * 28 = 12 * 7

There are 12 weeks in the period from Gb2-27 up to and including Gb5-12 (though the last day is cut off short). 52 * 7 = 364 at vaha kai in Gb5-10 says there is not room for another week. The measure is full.

By using the longest measure, 31 days per month, the end comes with Gb5-18. The following glyph is an empty-eyed moa announcing the beginning of a new season.
