Next we will compare the preceding manu rere in Ga4-16 (where 4 * 16 = 64, a sign of growth) with manu rere in the 2nd period:

2
	Ga3-6 (66)	Ga3-7	Ga3-8	Ga3-9
13
	Ga4-16 (100)	Ga4-17	Ga4-18	Ga4-19

Maro at right in Ga4-16 seems to indicate the limit of a season beginning at Ga3-6, which impression is confirmed by ordinal number 100 (counted from Gb8-30).

The season measured out should be a season of spring sun. Not only can we read this from 4-16 (because spring sun generates growth), but also from 3-6 (as in 36 = 6 * 6) and from ordinal number 66.

If we arrange this assumed early spring season from Rei in Ga2-27, it will measure 42 glyphs (6 weeks):

	2		4		33
Ga2-27 (58)		Ga3-1 (61)		Ga3-6 (66)		Ga4-16 (100)
42
