4. Towards the end of Dawn Breaker (at day number 8 / 24 * 365¼ = 121.7) is another 'break' in the text flow (the first being the turnover from side b to side a):

End of 7th hour (and of Dawn Breaker)
Ga2-24 Ga2-25 Ga2-26 (57)
No named star yet found.
period 1
Ga2-27 (*122) Ga2-28 Ga2-29 (60)
Naos (122.3)  Heap of Fuel (123.1)  Tegmine (124.3)
Ga3-1 (*125) Ga3-2 Ga3-3 Ga3-4 Ga3-5 (65)
Al Tarf (125.3) Bright Fire (126.4) Avior (127.4)    

Rei in Ga2-27 is the first glyph in the 8th hour and it is also the first glyph in a long sequence which seems to end not until 6 days before Antares:

period 31
Ga7-5 Ga7-6 Ga7-7 (*177) Ga7-8 Ga7-9 Ga7-10 (180)

Clearly this long sequence is meant to be a unit. The unit is divided into 31 groups of glyphs which I have named 'periods'. There are 31 glyphs similar to Ga3-5 and Ga7-10 and they are distributed seemingly without much order among the 180 - 57 = 123 glyphs which appear to constitute the total unit. But maybe we should let the sequence continue to glyph number 12h / 24h * 365¼ = 182.6:

Ga7-11 Ga7-12 Ga7-13 (12h) Ga7-14 (184)

If the calendar year should begin at Ga1-1, then half a year ought to end somewhere here. Exactly where is dependent on several factors, for instance the length of the assumed year. And maybe we should begin with Gb8-27 - at the beginning of 4h in order to reach an 'octave' (12h - 4h = 8h).

On the other hand, by counting from spring equinox (0h) the day number at Ga7-13 will be 64 + 183 = 247, or 3 days before the heliacal rise of Antares:

Ga7-15 Ga7-16 (*250)

When I thought about what name to give the part of the dictionary beyond Dawn Breaker the curious figure in what I have come to call the 'henua calendar' inspired me to see someone climbing a tree. Thus the name became Tree Climber:
