Posnansky has suggested that the triplet of 'day signs' incised on the Gateway of the Sun indicates the originators used a 'week' with 5 days:

The order between the days signs, which Posnansky has given with his numbers, should be changed, though, because his number 2 (center above) is a special case, where the 'crown' has a fish head in front, and where by cause of the bird striving upwards (from the watery world of the fishes) the 'crown' has dipped down to become invisible from above. Also the arms, legs, and wings of this bird have fish signs.

Therefore Posnansky's day sign number 2 should denote the beginning and be placed as number 1 in the triplet. From 'the kingdom of the fishes' evolution will result in creatures on land and in the air. They were not stupid, those who built the Gateway of the Sun, they could read the signs of mother nature.

Posnansky's number 3 corresponds to side a on G and H, and number 1 to side b (excepting the last 58 days which belong to number 2).

I do not suggest that Posnansky was wrong in identifying these 'day signs' with 5-day weeks (if that is what he meant, I cannot rely 100% on my memory). Instead I endorse his idea of a 5-day week. There will be 72 such in a year with 360 days, and - we should remember - there are 400 + 72 = 472 days in the text of G.

The 7-day week is connected with the cycle of the moon. They counted with fortnights, not with 7 nights, as the basic time unit. A pair of weeks is a fortnight and a pair of fortnights is the length of a month, defined by the number of nights moon could be shining in a row. 2 * 14 = 28.

Measured by the cycle of the sun the basic time unit was not 14 but 15, because 2 * 15 = 30. An ordered 360-day year is equal to 24 * 15 days (which probably explains why we still have the idea that a day is equal to 24 hours).

The sun cycle has two half-cycles, 12 * 15 = 180 days in each. We feel it necessary to divide 24 hours into two equal parts, and I suspect we measure a circle by using its radius, not its diameter, because we wish to have a pair in the formula 2 * r * π.

From these considerations a week cannot be 7 days long, it must be a 5-day long week (3 would be too short and 15 too long). With a 5-day week we can count to a week by using the fingers on one hand. Fingers (rima) will that way be associated with number 5 (rima).

Possibly the ideas above can be applied when trying to interpret the triplet of 5-feathered ariki in G:

Ga5-24	Ga6-3	Ga7-6

 

Tama is at 14 * 29.5 = 413, but tamaiti comes at 414:

Gb6-26	Gb6-27	Gb6-28	Gb7-1	Gb7-2 (413)	Gb7-3	Gb7-4
Gb7-5	Gb7-6	Gb7-7	Gb7-8	Gb7-9	Gb7-10	Gb7-11
Gb7-12	Gb7-13	Gb7-14	Gb7-15	Gb7-16	Gb7-17 (428)

The kuhane station is not named Tamaiti, and we can guess the reason:

Gb6-26	Gb6-27	Gb6-28	Gb7-1	Gb7-2	Gb7-3	Gb7-4
Gb7-5	Gb7-6	Gb7-7	Gb7-8	Gb7-9	Gb7-10	Gb7-11

At winter solstice (Gb6-26) old sun has stopped and moves no more, he is 'dead'. Tamaiti at Gb7-3 is the new sun, but still only a child. I have blackmarked glyphs which seem to be associated with the old sun, and redmarked those denoting the son of old sun.

Moa in Gb7-1 is no real cock, the circumference of the glyph is not closed. Yet he is calling out the arrival of the child. In Gb6-27 another precursor of the new sun could be the curious sign emerging from henua (the mother). The sign at the top is drawn like a flame (tao).

In Gb6-28 tagata is at left and the same henua at right. Gb7-2 is the last glyph in the great lunar cycle, viz. number 413 - it cannot refer to the new year. Gb7-4 is a strange hau tea without any eye, light has vanished and it must refer to the old year.

Gb7-6 is a 'midnight henua', which means the new year has begun. Apparently Gb7-4 is the last glyph of the old year. No other 'midnight henua' can be found in the text of G.

Tama is not tamaiti, tama is the old sun, not the new sun child.

Ariki in Gb7-11 has the same sign at top left as tamaiti in Gb7-3:

	7
Gb7-3 (414)		Gb7-11 (422)
1		9

Possibly it means 'there is nothing at left' (this is the beginning). 58 + 422 = 480 = 24 * 60.

The glyphs which follow seem to refer to the moon:

Gb7-12	Gb7-13	Gb7-14	Gb7-15 (426)	Gb7-16	Gb7-17 (428)

For once a fat mago comes first and a lean one in second place. The reason is that the fat one is pregnant. Hau tea at Gb7-14 is double-eyed (Janus). It is different from hau tea in Gb7-2 - it is not leaning - moon behaves in the same way irrespective of the sun season.

In Gb7-16 the same mago no longer is pregnant, she has given birth. Presumably the child is depicted in Gb7-15. Its ordinal number counted from tamaiti last year is 58 + 426 = 484, and possibly it is no coincidence that 48 * 4 = 192.
