We are going to continue by using results from the link 'here'. The first of the 13 simple henua glyphs is located at the beginning of what we have referred to as 'summer':

274

Gb5-6 is glyph number 274 from Ga4-3. It is also number 360 counted from the beginning of side a (including the last glyph on side b). It would be strange if summer ended at midwinter, therefore the assumption has tacitly been that the year is ending and beginning anew at autumn equinox (or thereabouts). Gb5-6 could therefore be both at the end of summer and at the end of the year.

But 274 glyphs (= days) is ca 9 months, and 86 glyphs (before Ga4-3) is ca 3 months, which means Gb5-6 hardly can be at autumn equinox. Summer does not stretch all the way to Gb5-6. We must redraw our preliminary map of the year.
