We can try to put in days, using 2 glyphs per day and count with day 1 equal to Aa1-1--2:

6-24 (ariga erua) can be understood as sun's (6) end (24), because 6 * 24 = 144 = 12 * 12. And 22 (as in day 22 * 10 = 220) maybe alludes to the formula: The circumference of a circle = its diameter times 7 * π. Measuring a circle you can begin anywhere, but once you come back to the beginning you have reached its end.

Alternatively, we could count days from nuku in Ab8-41:

This alternative seems to be in a better harmony with the glyphs, e.g. are Aa6-30--31 obviously a pair and Aa6-30 connected with Aa6-31.

The ordinal number for koti in Aa6-23 will be changed from 439 to 439 + 45 = 484, which can be interpreted as 48 * 4 = 192. The 'henua season' is ending, henua koti.

Beyond day 240 a Rei glyph indicates the beginning of another season (beyond 8 months à 30 days), and 6 * 20 (in Aa6-20) = 120 is what remains to day 360. These last 4 months evidently are beginning before the previous 'henua season' has ended.

We can compare with G:

Metoro said pu (hole) at henua koti (Aa6-23) and in Gb1-10 there is also has a 'pu' (in addition to a lost head at right). The dramatic events which follow in Gb1-13 - we can imagine - resemble to a certain degree what happens at the same time (day 243) according to Aa6-24--25. Someone is going down, and 243 is a number we should recognize:

If now the 8th station of the moon is so important as to determine what is half the text of G, then it probably means that also the 8th station of the sun (240) should be important. This could be the true explanation for henua koti.

There is a moe glyph in Aa6-17, the last glyph before day 240. Moe, we have deduced, indicates the last part of a period, the time when the new period not yet has arrived but when - like in early dawn - we can observe its effects. In addition it must be mentioned here that there is a sign '6-17' which indicates beginning.
