The last period of the G calendar - in which the final glyph of each period is of the type kiore-henua-maro - begins with a variant of ihe tau: Ga7-5 Ga7-6 Ga7-7 Ga7-8 Ga7-9 Ga7-10 The parallel K period instead has a glyph where marama is the central part: Kb4-10 Kb4-11 Kb4-12 Kb4-13 Kb4-14 There seems to be a correlation between ihe tau and the final stage of a calendar. The ariki (chief) and henua ora ('recycling station') glyphs which follow support the suggestion that a great season is 'finished'.

At Kb4-10 (163) sun is still present on the land. The king (ariki) in Kb4-11 is drawn with an unbroken contour line. But in Kb4-12 the 'recycling station' (henua ora) has arrived. 4 * 12 = 48 = 8 * 6, the measure is full.

In Ga7-6 ariki has a 'broken' contour line and the number is 176, possibly to be interpreted as 8 * 22 (where 22 could be 3.14). It is easy to read the ordinal numbers from the beginning (at Gb8-30) because e.g. 7-6 becomes 176.

We should notice that 8 * 22 = 6 * 29.5 - 1, a fact which ought to have impressed the rongorongo writers. In a way it means that Nga Kope Ririva must lie outside the domain of the sun (given that his measure is given by the moon to be 8).

With 22 as a measure for a completed cycle, we can apply it to 165 at Kb4-12, because 165 = 7.5 * 22, maybe implying that there still are 0.5 * 22 = 11 glyphs (days) remaining:

Kb4-15	Kb4-16	Kb4-17	Kb4-18
3	4	5	6
	...
Kb4-19	*Kb5-1	*Kb5-2	*Kb5-3 (175)
7	8	9	10
				...
*Kb5-4	*Kb5-5	*Kb5-6	*Kb5-7	*Kb5-8
11	12	13	14	15

Only one more ihe tau glyph is found in this G calendar (i.e. the one characterized by kiore-henua-maro): 29 Ga6-27 Ga6-28 Ga6-29 Probably it is significant that it is in the 29th period - the 29th night of the moon is completely dark, as if the moon had died. Counting glyphs from Gb8-30 we will find Ga6-27 to be glyph number 168, a sign which determines that the preceding glyph was the last one in a cycle consisting of 167 glyphs. 28 Ga6-24 Ga6-25 Ga6-26 165 166 167 Rau hei in Ga6-25 confirms our interpretation - it shows a 'dead fish' hanging head down.

With the 29th period indicating the dark new moon phase, a waxing moon will come beyond. But the glyphs seem to tell about the absent sun rather than about a rising new moon:

Ga7-1 (171)	Ga7-2	Ga7-3	Ga7-4
Ga7-5	Ga7-6	Ga7-7 (177)	Ga7-8	Ga7-9	Ga7-10
Ga7-11	Ga7-12 (182)	Ga7-13	Ga7-14
Ga7-15	Ga7-16 (186)	Ga7-17
Ga7-18	Ga7-19	Ga7-20	Ga7-21	Ga7-22 (192)

In Ga7-22 we can read 7 cycles (7 * 22 = 154). But 192 cannot be divided by 22, instead it is 8 * 24.

8 * 22 = 176 instead is the last glyph before Nga Kope Ririva - the one which is 11 glyphs beyond henua ora at Kb4-12.

Glyph number 7 * 22 = 154 is Ga6-13:

24
	Ga6-12	Ga6-13	Ga6-14	Ga6-15	Ga6-16
	153	154	155	156	157
