Once again. From a similarity between Saturn and Mercury in Aa1-18 respectively Aa1-22 - where the planets have been defined by Mercury at Aa1-1 - and from their long straight necks (among other things) I think they are meant to represent the Tree at winter solstice respectively at summer solstice:

When you say 'one' there must have elapsed as much time as is equal to your standard of measurement. In the beginning there is darkness, the unknown.

Thinking in terms of the Moon, the month should begin in her 2nd half of waning. When new moon is showing herself again, it should be the beginning of the 1st week of the month according to the calendar. The first - 'unknown' - quarter is now in the past, light has returned and we know what time it is.

The 20th night of the moon should be - if we are using the same concept - the last night of the 3rd week of the month. Because the first night of the 1st week is dark (has not been counted). Therefore the 20th night indicates that we have reached to the end of the 3rd week.

This explains why we should count 20 * 13 = 260. It means 21 * 14 = 294. The 294th night is the very last day of the Sun.

The flattened suns (in Aa1-18 and Aa1-22) is a further sign. And 22 at Mercury refers to midsummer we have learnt from Homeros.

The flow of planets from Mercury at Aa1-1 to Aa1-21 is an indication that we can rely on the weeks at least so far.

Then we can observe that the break in time at Aa1-15 also is at Mercury:

And, furthermore, Mercury occurs also at Aa1-8 at a reasonable place - given that each glyph represents 20 days:

Aa1-1	Aa1-2	Aa1-3	Aa1-4
Aa1-5 (100)	Aa1-6	Aa1-7
Aa1-8	Aa1-9 (180)	Aa1-10
Aa1-11	Aa1-12 (240)

Aa1-9 is at the position of Jupiter, and apparently he has lost the top of his front member (maybe from circumcision at his earlier initiation). 20 days later a more severe damage maybe will finish (hatiga) him. At Aa1-11 his spirit is trying to rise but seems to have been caught in kaikai.

Maybe there is 'double-talk' here, with Aa1-5--8 both functioning as quarters (90 days for each glyph) and as 20-day glyphs. Sun (Aa1-5) ought to be at new year and Mercury (Aa1-8) at midsummer.

On the other hand, the coloured balls of Atan are placed just before full moon, and the corresponding structure for the sun is midsummer:

Atan  (Heyerdahl 4)			Englert	Métraux (Thomson)
10	he popo tea	white ball	Ohua	Atua (Otua)
11	he popo mea	pink ball	Otua	Hotu (Ohotu)
12	he popo uri	black ball	Maure	Maure
13	he popo hega	red ball	Ina-ira	Ina-ira
14	he raakau (= rakau)	plant	Rakau	Rakau
15	he omo tohi	full moon	Omotohi	Motohi (Omotohi)
Hotu (Ohotu) is the star (hoku in Hawaiian) 'fruit' and corresponds to Ohua.

With the colours of Atan Mercury becomes black and Jupiter red:

Aa1-6	Aa1-7	Aa1-8	Aa1-9	Aa1-10
white	pink	black	red	plant
120	180	240	300	360

This structure could give 60 days to each glyph. Notably the position of Moon at Aa1-6 generates day 120 also with 20 days per glyph - if we begin our counting at Aa1-1.

Day 120 is also the position of Aa1-24, because once we have reached 360 at Aa1-18 the counting should begin anew: Sun appears at the beginning of the new year (whichever measure we are using forward - quarters or months or whatever):

Aa1-19	Aa1-20	Aa1-21	Aa1-22
Aa1-23	Aa1-24 (120)	Aa1-25	Aa1-26 (160)
Aa1-27	Aa1-28 (200)	Aa1-29	Aa1-30 (240)
Aa1-31	Aa1-32 (280)	Aa1-33 (300)

At Aa1-26 Sun seems to be given a fatal blow, and I think we can rely on the planets at least up to this point.

The number game indicates that also Aa1-33 (= 22 + 11) should be the end of Sun. It is a toga glyph and 300 will fit with 20 days per glyph.

Aa1-11 (220)	Aa1-22 (200)	Aa1-33 (300)
Saturn	Mercury	Sun

I have here counted to 200 at Aa1-22 from Aa1-15 (300) instead of from Aa1-18 (360).

In order to reach 100 for Saturn at Aa1-11 we similarly need to begin counting from Moon, but it is not very convincing:

Aa1-1	Aa1-2	Aa1-3	Aa1-4
Aa1-5	Aa1-6 (120)	Aa1-7
Aa1-8	Aa1-9	Aa1-10
Aa1-11 (100)	Aa1-12

Counting on, we find day 400 to be at a reasonble place:

Aa1-37	Aa1-38 (400)	Aa1-39	Aa1-40	Aa1-41	Aa1-42 (480)

Venus should be here, at the beginning of a new year. But then it becomes doubtful, because time should stop at 400. Maybe Aa1-39--42 constitutes a special quartet, because with Aa1-43 Sun should return as a baby again:
