Te Pei is the season of the haddock:

A black hole through the fish is where sun enters and comes out again. The Dogon shrine (in Ogotemmêli) makes it even more clear:

3 * 8 = 24 squares in the checquer-board above says the holes are for the sun.

Tehetu'upú is presumably the month of the hole, and therefore it should coincide with Te Pei. But there is only one such 'hole' month. And Te Pei can be used both for leaving (at the beginning of side b of G) and for entering (at the beginning of side a of G). Yet, these two beginnings work differently - at the beginning of side b it is the hole through which sun leaves and at the beginning of side a it is the same hole but now he returns.

Geographically regarded, Te Pei at the beginning of side a should correspond to the origin from which sun leaves towards Nga Kope Ririva in the west. He has only half the coast, because the other half, from Te Pei eastwards to One Tea is used after sun has left the island at Nga Kope Ririva.

It all makes sense in a peculiar way. There are two cycles in the year, it begins with the sun cycle and he moves from the center at Te Pei towards west and leaves the island from Nga Kope Ririva. Then comes the next cycle, when sun is absent on the other side of the equator, and it also begins from the center at Te Pei, but moves in the other direction.

Te Pei must be the solstice, when time stands still. Sun grows in height to Te Pei and there he is cut short. Then the movement is in the opposite direction, ultimately to reach solstice again. It is the same solstice, the same hole, the same Te Pei. And now the 2nd cycle is being toppled, disappearing through the hole, loosing its head:

Where waning moon is reaching her end (beyond One Tea) there is a black hole (new moon). From this hole waxing moon emerges.

When waxing sun is reaching his end (beyond Nga Kope Ririva) there is a black hole and from this hole waning sun (rain) emerges:
