As these 16 glyphs (8 + 8) obviously should be read as 7 periods, logic tells us that they probably taken together constitute a week. Let us try take a closer look at that possibility:
henua + arm with 'sun-cat' head hakaturou with three slightly different shapes
+ sign of sun + slightly broader henua + shape like upright arms unmarked somewhat small + 'head' of 'sun-cat' indicating closeness to open 'mouth' (see left) rather open haga + 'head' of 'sun-cat' not looking so much upwards 'head' of 'sun-cat' like in toko te ragi
(2 + 2 + 2 + 2)  +  (2 + 3 + 3)  =  8 + 8  =  16 glyphs

(3 + 2 + 3 + 1)  +  (2 + 4 + 1)  =  9 + 7  =  16 'heads' / 'nuts' / 'fruits'

Is there a subtle indication of viri in the first and the last glyph? Also in the 2nd and the 2nd last glyph. In addition the 2nd last glyph shows the typical sign of 'handing over' (to the next week, i.e. to the sun).

But then the uplifted arms in the first glyph should indicate 'taking over', 'receiving'. There is a 'sun-ball' at left. A play with balls? Or nuts, eggs? There are two hua (at Jupiter and Venus). The hua are as in autumn, the first part of the dark season, when fruits are ripening.

The straight neck and head of the 2nd glyph indicate toko te ragi. Is there a cardinal point each sunday? There is light in the 'feet' of the 2nd glyph.

The 'splendid bird' is here marking moon, which perhaps is indicated by an up-lifted moon-like wing.

Mars and Venus have the same type of glyph, a kind of double. Presumably this kind of glyph means 'double appearance', 'double face'. Mars is sometimes slow, faint and far away, sometimes close by moving fast. Venus is sometimes seen in the morning, sometimes in the evening.

Mercury seems to be a waterhole, but also like a 'solstice', because viri is there too. Perhaps we should regard this point in the week as the point where light is mixing with darkness (water).
