The ordinal numbers of glyphs should not be relied upon. The signs in the glyphs are much more trustworthy. Assuming the 19 'feathers' in haú (at Gb2-17) refer to a sequence of 19 glyphs ending there, we can count backwards to find Gb1-24 located at time zero:

Gb1-24 (0)	Gb1-25	Gb1-26	Gb2-1	Gb2-2
Gb2-3	Gb2-4	Gb2-5	Gb2-6	Gb2-7
Gb2-8	Gb2-9	Gb2-10 (12)	Gb2-11	Gb2-12 (14)
Gb2-13	Gb2-14 (16)	Gb2-15	Gb2-16	Gb2-17 (19)

Using the cues in the glyphs will suggest Gb2-13--17 should have a meaning similar to what can be read in Aa1-46--48, Aa1-16--17.

Gb2-9	Gb2-10	Gb2-11	Gb2-12
Aa1-42	Aa1-43	Aa1-44	Aa1-45
Gb2-13	Gb2-14	Gb2-15	Gb2-16	Gb2-17
Aa1-46	Aa1-47	Aa1-48	Aa1-16	Aa1-17

The first period in the calendar of the daylight has a reversed tapa mea (Aa1-17) indicating sun has not arrived yet. The last glyphs in the calendar of the night (Aa1-46--48) of course must connect to the first glyphs in the calendar of the daylight. The ordinal numbers in the glyph lines, b2-16--17 respectively a1-16--17, are more reliable than ordinal numbers counted from some distant point.

The strange eating gesture in Gb2-15 has a parallel in the strange eating gesture in Aa1-48. Signs of ragi unite Gb2-14 and Aa1-47. 46 (in Aa1-46) indicates an end (cfr 1,334 = 46 * 29), which means Aa1-47 should be a new beginning. Reading the words of Metoro we can understand the sky (ragi) is beginning to dawn (Aa1-47), followed by the first light reaching also down to earth (Aa1-48).
