The lowest measure for indicating Te Pei (the 8th kuhane station) is 8 * 28.5 = 228:

Ga8-24 (228) Ga8-25 Ga8-26 Gb1-1
Gb1-2 (232) Gb1-3 Gb1-4 Gb1-5
Gb1-6 (236) Gb1-7 Gb1-8 Gb1-9

And:

... The distance from the first to the second of the two redmarked hanau glyphs is 70:
69
Ga6-17 (158) Ga8-24 (228)

8 * 24 (as in Ga8-24) = 192 (which is the number of glyphs in K). 228 - 192 = 36, and the 36th glyph (counted from Gb8-30) comes in the 3rd period of a 6-period calendar:

1 1
Ga2-1 Ga2-2 Ka2-11 Ka2-12
2 2
Ga2-3 Ga2-4 Ka2-13 Ka2-14
3 3
Ga2-5 (36) Ga2-6 Ka2-15 Ka2-16
4 4
Ga2-7 Ga2-8 Ka2-17 Ka2-18
5 5
Ga2-9 Ga2-10 Ka2-19 Ka2-20
6 6
Ga2-11 Ga2-12 Ka2-21 Ka2-22

Halfway through this calendar means midsummer if the calendar stretches for a year.

In other words: 228, the lowest number indicating Te Pei, is a much higher number than 180 (or 182 etc) which we would expect for half a year (and for the first side of the G tablet). In K there is a more reasonable 192 for both sides, and the short text presumably covers only the first half of the year.

228 - 192 = 36 is the difference to be accounted for, and Ga2-6 is glyph number 36 if we count from Ga1-1. It stands as glyph number 6 in the 12-glyph long calendar, probably mapping the whole solar year, cfr e.g. Ga2-10 where there is a hole through which sun can leave in autumn. And moe in Ga2-34 is suitably located where the light from spring sun has appeared. 6 double months, with one glyph for each month.

We have earlier discussed why the text of K does not stretch to 228.

... by adding the distance between Ka3-14 and Kb3-7 to 144 we will reach 228, i.e. 36 days beyond the end of the text of K:

82 35 ... 11 35 -
Ka3-14 (60) Ka3-15 Kb3-7 (144) Kb5-8 (180) Kb5-20 228
84 36 12 36
84
168 = 6 * 28
