Gb1-2 (232) Gb1-3 Gb3-15 Gb6-26 (409) Ga5-10 (121)
177 = 6 * 29.5

The table above shows that 177 days from Gb1-3 up to and including Gb6-26 can be added to the following 183 days (to Ga5-10), i.e. a year with 360 days is measured out.

From Gb1-3 to Gb6-26 the height of honu is increasing; Gb1-3 is at summer solstice and Gb6-26 at winter solstice.

Gb6-26 is situated in a structure with 2 * 7 = 14 glyphs, where the first septett refers to the first half of the year (spring) and the second to the second half (autumn):

Gb6-17 (400) Gb6-18 Gb6-19 Gb6-20 Gb6-21 Gb6-22 Gb6-23 Gb6-24
Gb6-25 Gb6-26 Gb6-27 Gb6-28 Gb7-1 (412) Gb7-2 Gb7-3 Gb7-4

In Gb6-18 hipu strives upwards, in Gb6-26 the 'sack' is at the bottom. A tamaiti arrives close to the end of the year (position 13 of 14), and Tama is the 13th kuhane station. 14 * 29.5 = 413 (at Gb7-2).

The 3 redmarked glyphs has a special function, they serve as intercalated days, increasing the waning sun season from 177 to 180 days. Moa at Gb7-1 is the last glyph of waning sun. We can therefore revise the table into:

98 76
Gb1-2 Gb1-3 Gb3-15 Gb6-26
177 = 6 * 29.5
180 = 6 * 30
Gb6-27 Gb6-28 Gb7-1 Ga5-10

From Ga5-10 up to and including Gb1-2 there are 233 - 120 = 112  = 4 * 28 glyphs:

54 54
Ga5-10 (121) Ga7-6 Ga7-7 (177) Gb1-2 (232)
112 = 4 * 28

The basic structure of the G text - with lunar months (16 * 29.5 = 472) - has an alternative reading based on a year with 360 days, completed with a calendar defined by fortnights: 6 * 60 + 8 * 14 = 472.
