Aa5-9	Aa5-10		Ab7-28	Ab7-29		Aa2-33	Ab6-37

Kara etahi evidently is a sign of a juvenile - in contrast to manu rere which apparently is the opposite, a sign of the 'spirit of life' leaving. Kara etahi comes at the beginning and manu rere at the end.

Aa5-9--10 seems to be a reversal of the natural order of time, but it can be explained by considering Aa5-9 as the glyph beyond the end of a period with 166 glyphs, while kara etahi is at the beginning of the following period:

Another example from Tahua, on the other hand, seems to indicate that the birth of a new season can occur before the 'spirit' of the old one is leaving:

80	324			194
		Ab5-1 (325)	Ab5-2		Ab7-25	Ab7-26
200 + 2		day 1		97	99

				138	64
Ab7-27	Ab7-28	Ab7-29 (525)	Ab7-30
0		0		100 + 1

The structure of the Tahua text has two parts, the longer of which is based on 8 periods with 99 + 2 glyphs, i.e. 8 * 101 = 808 glyphs in all. 99 is a number which presumably alluds to the cycle of Venus:

With 2 glyphs per day the long period will be 404 days. However, among them 16 glyphs (8 days) apparently do not count. Venus has 2 dark periods each of which measures 8 days.
