We have found that Gb6-20 possibly could be a glyph identifying the 'midnight' of the year and 'parallel' with Aa7-85 by cause of being glyph number 403 counted from Aa3-8:

Gb6-17 Gb6-18 Gb6-19 Gb6-20 (403)
Aa7-82 Aa7-83 Aa7-84 Aa7-85 (585)
400 401 402 403

Number 400 at henua in Aa7-82 seems to affirm ordinal number 403 for Aa7-85. A great period has been measured out. Beyond day 403 a new glyph line is beginning and we can look for similarities among the glyphs beyond Gb6-20:

Aa8-1 Aa8-2 Aa8-3 Aa8-4 Aa8-5 (590)
404 405 406 407 408
Gb6-21 Gb6-22 Gb6-23 Gb6-24 Gb6-25 (408)

The glyphs are very different, but we know that tagata means the final of a period and we know that Rogo at number 409 in G indicates the beginning of a new year:

Gb6-26 (409) Gb6-27 Gb6-28
Gb7-1 Gb7-2 (413) Gb7-3 Gb7-4

Day number 413 (Gb7-2) is a hau tea with double mata, one 'face' at the back and one in front (like Janus). Two glyphs later both these 'eyes' are gone and darkness has fallen (like a black cloth).

14 * 29.5 = 413. Then follow glyphs which are notable in several ways, first of all because of the 'midnight henua' at Gb7-6 (where 7 * 6 = 42):

Gb7-5 Gb7-6 Gb7-7 Gb7-8 Gb7-9 (420)

A new sun is bursting forth (Gb7-8) and is fully out in the open at position 420 (= 7 * 60). Position 417 is important and we can identify Aa8-14 as the equivalent position in A:

Aa8-6 (591) Aa8-7 Aa8-8 Aa8-9 Aa8-10 Aa8-11
409 410 411 412 413 414
1 2 3
Aa8-12 Aa8-13 Aa8-14 Aa8-15 (600) Aa8-16 Aa8-17
415 416 417 418 419 420
4 5 6

Glyph number 600 should also be of importance, and we can imagine the previous glyph to be a variant of the 'fire generator', this one though with an empty hand - there is nothing left. A similar hand is seen in Aa8-8 (where 8 * 8 = 64).

The fat mago at position 415 probably is illustrating how the sun is turning around in midwinter. Fat 'sharks' are well fed and can only be found after the season of growth (spring).

The curious tail of the shark presumably is there in order to draw attention - the proper tail can be found at the top end of the following Rei. By the process of turning around the bottom has become the top.

In G the mata signs presumably are expressing it in another way - the left 'eye' ('face') drops down to become the little bulb at the bottom of tamaiti:

Gb7-2 Gb7-3 Gb7-4 (415)

Counting with 2 glyphs per day:

Aa8-6 (591) Aa8-7 Aa8-8 Aa8-9 Aa8-10 Aa8-11
409 410 411
Aa8-12 Aa8-13 Aa8-14 Aa8-15 (600) Aa8-16 Aa8-17
412 413 414

Day 413 (= 14 * 29.5) is where the 'great month' is finished. Day 414 is in G a tamaiti glyph and 472 - 413 = 59. Two months remain before the reappearance of the 'front side'.

In A there are 670 - 600 = 70 glyphs to the end of side a, maybe representing 35 days. But we can go on to day number 420 (in order to have only 28 days left to the end of side a - or 52 in G):

Aa8-16 Aa8-17 Aa8-18 Aa8-19 Aa8-20 Aa8-21
414 415 416
Gb7-3 (414) Gb7-4 (415) Gb7-5 (416)
Aa8-22 Aa8-23 Aa8-24 Aa8-25 Aa8-26 Aa8-27
417 418 419
Gb7-6 (417) Gb7-7 (418) Gb7-8 (419)
Aa8-28 Aa8-29 Aa8-30 Aa8-31 Aa8-32 Aa8-33
420 421 422
Gb7-9 (420) Gb7-10 (421) Gb7-11 (422)

Gb7-8 has 5 flames as in Aa8-30. The positions are not exactly the same, but what could we expect? With different lengths of the glyph lines and with different dispositions of the complex material it is not surprising.

Several 'final days' could be here, not only at day 420. For instance is 416 = 8 * 52.

At day 418 we can count 8 * 24 = 192 and 8 * 25 = 200, or 7 * 7 = 49. If we add 6 days to day 416 we will arrive at day 422.
