A square measured out as 4 by 61 days for the first half of the year comes after 8 * 29.5 = 236 (Te Pei at Gb1-6). Sun is measured by 4 and moon by 8:

Gb1-5	Gb1-6 (236)	Gb1-7	Gb1-8	Gb1-9
Gb1-10	Gb1-11	Gb1-12	Gb1-13	Gb1-14 (244)
Gb1-15	Gb1-16	Gb1-17	Gb1-18	Gb1-19

If spring sun is finished after 244 days, there could follow 2 moon 'years' each with 8 by 8 = 64 days. 244 + 64 + 64 = 372 = 12 * 31:

Gb5-6 (360)	Gb5-7	Gb5-8	Gb5-9	Gb5-10	Gb5-11
Gb5-12 (366)	Gb5-13	Gb5-14	Gb5-15	Gb5-16	Gb5-17
Gb5-18 (372)	Gb5-19	Gb5-20	Gb5-21	Gb5-22	Gb5-23 (377)

Moa in Gb5-19 cries out, for a new year is being born.
