The last of the 4 pillars upholding the sky (Jupiter) is at Gb8-2, and we can see that his pillar is crumbling. Then follows Friday, the day of Venus, where the 5 + 5 = 10 hua 'feathers' ought to refer to the number of months for the sun. 400 is the whole cycle, I suggest, and sun is present during 10 * 20 = 200 of these. (The Polynesians on Gilbert Islands never counted the nights of the Moon beyond the 20th, we should remember.)

The 'tree' (henua at right in Gb8-2) is no longer 'living'. In Gb8-3 it has been turned upside down and a 'fruit' emerges in front - the father will live on in his son. Both day 3 and day 24 (= 8 * 3) are Venus days, and the miraculous transformation from one generation to the next takes place with Venus.

At Gb8-5 there is an exceptional reversed manu rere glyph which must mean the return of the 'vital spirit', who escaped from the old body earlier in the week. A new year has been born, and it is Sunday.

216 (at Saturn) is counted from Gb1-1, and this number (which we recognize from H) is equal to the sum of 125 (the cube of 5) and 91 (= 7 * 13). This cube of 5 is beginning with Gb1-1 and ending with the reversed hau tea at Gb5-1:

I have arranged it so that the returning manu rere in Gb8-5 will be day number 400, the day when the cycle will begin again. I only had to decide that the front side of the year must be 183 days long (half 366, the day number for Rogo according to my reading of Q). 183 + 217 = 400.

Why should we be forced to always count glyphs from the beginning of the front side (Gb8-30 or else). The two sides of the G text can alternatively be regarded as two separate calendars. The reversed manu rere is a strong sign which should not be ignored.

Its ordinal number from Gb1-1 is 217 which can be interpreted as 21 weeks, one more than 20. A new cycle has begun and the old cycle ended when its waning phase reached 20 * 7 = 140 days, a number we recognize from the end of waxing at ika hiku (Ga7-27).
