If each glyph stands for one day, then *Ca14-26 cannot be counted from Ca1-1 - given that we wish to have it located as day number 14 * 26 = 364.

389 - 364 = 25 and time must be counted from Ca1-26:

Ca1-19 Ca1-20 Ca1-21 Ca1-22 Ca1-23 Ca1-24 Ca1-25
Ca1-26 Ca2-1 Ca2-2 Ca2-3 Ca2-4 Ca2-5 Ca2-6

This seems to be entirely plausible. The 'head' in Ca1-26 is like a nut, the earliest point in life. And at front in Ca1-25 three 'fire fingers' are combined with a variant of 'the recycling station' (henua ora), which could stand for the last point of the preceding life. Both the glyph and its number in the line agree with Ga2-25, number 64 + 26 = 90 counted from Rogo:

Ga2-23 Ga2-24 Ga2-25 Ga2-26

However, we must also consider our Rogo in Ca3-25 (notice the same ordinal number, a square of 'fire'):

314 109 238 75
Ca3-25 Ca4-1 Ca4-2 Cb5-16
1 2 3 314

Here we have ordered the glyphs in pairs, assuming 2 are needed for 1 day:

winter solstice
Ca3-20 Ca3-21 (72) Ca3-22 Ca3-23 Ca3-24 Ca3-25 (76)

Rogo is the last glyph in line a3, and its day number becomes 38 if 2 glyphs are needed for 1 day. On the other hand 389 - 75 = 314:

311
Ca3-25 *Ca14-25 *Ca14-26 (389) *Ca14-27 *Ca14-28
1 313 314 315 316

If 2 glyphs are needed for 1 day, then *Ca14-26 becomes the 2nd half of day 157 (counted from Ca3-25). 1 glyph per day agrees better with the numbers of *Ca14-26 (where 14 * 26 = 364, a strong sign):

25 49 312
Ca1-26 Ca3-25 *Ca14-26 (389)
50 314
364 = 14 * 26

We can therefore provisionally assign day numbers accordingly:

*Ca14-12 *Ca14-13 *Ca14-14 *Ca14-15 *Ca14-16 *Ca14-17
350 351 352 353 354 355
*Ca14-18 *Ca14-19 *Ca14-20 *Ca14-21 *Ca14-22 *Ca14-23
356 357 358 359 360 361
*Ca14-24 *Ca14-25 *Ca14-26 *Ca14-27 *Ca14-28 *Ca14-29
362 363 364 365 366 367

Henua in *Ca14-16 (of the 'midnight type') is the shortest of all such in the Mamari text. 354 = 12 * 29.5 and if we interpret this henua as a staff for ruling, then Hatinga Te Kohe (where the kuhane broke her 'bamboo') presumably is alluded to. The staff was no longer as before. The sky roof became lower, because the staff holding it up had become shorter.

And we can compare with G, where day 355 indicates darkness by way of the reversed hau tea. Day 355 in C shows a very short 'staff' in front.
