Period 29 clearly is defined as:

Kb4-10 Kb4-11 Kb4-12 Kb4-13 Kb4-14

Kb4-14 is the last of its kind of glyph type. The line number (b4) and the ordinal number (14) suggest a connection with mago and the humpback:

...
Ka4-14 Ka4-15 *Kb2-14 *Kb2-15
0 1 51 glyphs 52 53

52 glyphs beyond Ka4-14 arrives *Kb2-14, indicating how 52 periods are ending. Another 52 glyphs cover the difference up to *104 (the number of glyphs in periods 0 to 28). 29 of them come at the end of the calendar, beyond *Kb2-14 and the rest at the beginning (up to and including Ka4-14) - given that we include the 2 glyphs in period 0. 29 + 21 + 2 = 52.

There are 52 weeks in a year. Therefore there should be 2 glyphs for each week in the calendar (one for the nights and one for the daytime). A year composed of weeks contains 52 weeks, amounting to 364 days. Summer seems to have 26 weeks (52 glyphs) and winter should then also have 26 weeks (52 glyphs).

Period 29, which is the last period of the regular calendar, is divided in two parts:

29
Kb4-10 Kb4-11 Kb4-12 Kb4-13 Kb4-14
103 104 1 2 3

If we disregard the 2 glyphs in period 0 (which are outside the regular calendar), Kb4-11 will be the very last glyph of the regular calendar. Then comes henua ora (the 'recycling station') as glyph number 1 in a group consisting of 3 (in period 29) + 4 (30) + *4 (31) + *3 (32) + 2(0) = *14 + 2 glyphs. The asterisks mark uncertainty as to the number of glyphs.

The *16 glyphs outside the regular calendar could mean 8 days. 8 + 364 = 372 = 12 * 31.
