Period 0 we first defined as containing the 3 glyphs Ka3-12--14, later (at hau in the dictionary) we redefined period 0 to be:

Ka3-8	Ka3-9	Ka3-10	Ka3-11	Ka3-12	Ka3-13	Ka3-14

Now, considering evidence which points at Ka3-12 being the 8th and last of a group where this type of glyph marks the end of a period, it becomes probable that period 0 should be once again redefined, now to include only the two glyphs at the end.

The 'fire fingers' in Ka3-13 and Ka13-14 possibly refer to the 1st respectively the 2nd half of the year, both of which are being 'ignited' at the beginning of the year.

The new definition of period 0 regroups Ka3-8--12 together with the preceding 3 glyphs into:

Ka3-5	Ka3-6	Ka3-7	Ka3-8
Ka3-9	Ka3-10	Ka3-11	Ka3-12

The beginning of line a3 evidently consists of 4 glyphs which belong together as a first third of the 12 glyphs:

Ka3-1	Ka3-2	Ka3-3	Ka3-4
