Aa1-80 resembles those tagata + manu rere glyphs we have seen recently, though here Rogo is at left:

28 180 199
Aa1-61 (361) Aa1-80 (390) Aa4-10 (261) Aa6-45 (461)
200 200

Presumably Aa1-80 identifies where winter solstice is meant to be in the text. Rogo is here the same 'person' as the eating creature at right - Rogo marks the beginning of spring.

From Aa1-80 up to and including Aa4-10 there are 182 glyphs, maybe days, which is congruent with a 364-day long year (364 = 2 * 182):

180
Aa1-80 (1) Aa4-10 (182)
180 17
Aa4-11 (183) Aa6-27 (364) Aa6-45 (382) Aa6-46

13 * 29.5 = day 383½ lies beyond the pair in Aa6-45. 64 * 6 = 384.

1 glyph per day is a method which apparently gains support from the glyphs:

Aa4-11 Aa4-12 Aa4-13 Aa4-14 Aa4-15 Aa4-16
183 184 185 186 187 188

Midsummer evidently is indicated by the very open pure sign - light is coming in. In Aa4-13 the 'person' in front hides the sun and we can only see his flames. It ought to be a sign of summer solstice because there are 3 feathers at left and 4 at right in the following 'uplifted fruit' (hua reva). Tapa mea in Aa4-16 (where 18 * 8 = 144) has 8 short feathers at right, probably a sign of the new 'moon' season on its way.
