The Rogo type of year is, though, special. Light disappears. The other two 'years' (rather half-years) are characterized by henua glyphs in full view. They are in glyph line 14, a fact which points at the moon.

To reach Rogo at Ca13-20 in day 363 it is necessary to begin with day 1 at Ca1-1. 363 is possibly equal to 180 + 183 (alternatively to 183 + 180). Let us look:

	174
Ca1-1 (1)		Ca7-8	Ca7-9 (177)	Ca7-10	Ca7-11	Ca7-12 (180)
				177 = 6 * 29.5
Ca7-13	Ca7-14 (182)	Ca7-15	Ca7-16 (184)		Ca13-19	Ca13-20 (363)

The half-way mark lies in the 3rd period of the moon calendar. Ca1-1 contains a vero sign. At Ca7-9 time has reached 6 lunar months from that vero.

The 2 first of the 9 glyphs of the 3rd period are at the end of these 177 days. And now we understand the reversed extra kai sign in Ca7-9. It means the season of growth has ended (here).

A week is needed to reach to the beginning of next 6 lunar month period. 177 + 7 + 177 = 361, and then follow a vero influenced by Rogo.

363 = 177 + 7 + 177 + 2. Yet, the structure of the periods of the moon calendar says: 363 = (177 + 3) + (4 + 177 + 2) = 180 + 183.

The marama glyph in Ca7-13 indicates 'a night', and its form is that of waxing moon (south of the equator). Ca7-10, though, has a waning moon. However, this fact cannot be used to prove that the turnaround occurs before Ca7-12, because in that glyph the sun has a prominent sign at bottom which presumably means 'here is the upside down apex'.

We have also learned that full moon in the moon calendar comes after the half-way mark to Rogo.

Maybe the 8 periods of the moon calendar are doubles, i.e. the 4th period corresponds to the 8th kuhane station (8 * 29.5 = 236). Not until then comes the 'back side'.

13 * 20 = 260 could mean we should investigate glyph number 363 - 260 = 103 (alternatively glyph number 363 + 260 = 623):

		377		100					256
Ca13-19	Ca13-20 (363)		Ca1-1 (1)		Ca4-26	Ca4-27 (103)	Ca4-28	Ca4-29
380					260

260 + 380 = 640 = 32 * 20.

The other alternative - with Rogo at the beginning of 260 days (or at least glyphs) - is more convincing.

glyph numbers are counted from Cb1-1
Cb9-25	Cb9-26	Cb9-27	Cb9-28	Cb9-29	Cb9-30 (230)
Cb10-1 (231)	Cb10-2	Cb10-3	Cb10-4	Cb10-5	Cb10-6 (236)
Cb10-7	Cb10-8	Cb10-9	Cb10-10 (240)	Cb10-11	Cb10-12
Cb10-13	Cb10-14	Cb10-15	Cb10-16	Cb10-17	Cb10-18 (248)
Cb10-19	Cb10-20	Cb10-21	Cb10-22 (252)

At Cb10-22 Metoro said kua vero. Then follows glyph line Cb11.

In Cb10-19 we recognize Cb12-12:

			62 + 236
Cb12-10	Cb12-11	Cb12-12 (1)		Ca9-9 (300)

But in Cb10-19 the neck of the bird is broken.

By adding 63 to 252 (at Cb10-22), we reach 315. Likewise, if we add 63 (this time not 64) to 252 (counted from Cb8-30) at Gb1-22 we will have 315:

Gb1-13	Gb1-14	Gb1-15	Gb1-16	Gb1-17	Gb1-18	Gb1-19	Gb1-20
Gb1-21	Gb1-22 (315)	Gb1-23	Gb1-24	Gb1-25	Gb1-26	Gb2-1	Gb2-2

The strange Gb1-21 is more at is proper place this way.
