1				236 = 58 + 178

When we in G have found 236 as a day beyond which sun seems to be vanishing, we have not counted with any 58 dark days before Gb8-30:

If we try to add those 58 dark days (from tamaiti at day 414 up to and including day 471 at Gb8-29), day number 236 will come earlier and on side a:

58 + 178 = 236 and 6 * 29.5 = 177. The period number is 31, the last of them. Half 236 is 118 (= 4 * 29.5) and if we locate this day we will find the glyph in period number 1:

By using the 58 dark days at the beginning of the calendar round, the creator of the text has accomplished reaching 4 * 29.5 at Ga2-29. By adding 2 * 29 to 60 (which has been counted from Gb8-30) the sum will be equal to 4 * 29.5.

The strange variant of niu in Ga2-29 (alluding to 2 * 29 = 58) enables the counting of lunar months to be coordinated with a beginning in absolute darkness.

Furthermore, we can imagine the newborn midwinter child to be like a little black shark (mago):

		... to the east, there is Tama, whose addition 'an evil fish with a long nose' is explained by Juan Tepano to mean 'a shark' ... and may be connected with the youngest son of Hotu Matua ...

Niu is a word which may have been in the head of the creative person who gave the name niuhi to the hammerhead shark.
