And then there is the confusion created by there being more than one 'year' in a year. GD24 might express the 'year' (= half year) from autumn equinox to spring equinox'. A hole for the sun go through into the underworld (then he surely will be north of the equator) and then another hole half a year later through which the sun will come back. Though GD24 is also used in the calendar of the day, which probably means that the underworld is also the night.

Is then GD24 without holes = 'summer' (and also that part of the day which is light)? It really ought to be like that if there was strict logic and order in this system of writing glyphs. But there is a 'school' of writers (H and Q) which evidently has chosen another way, because their parallel glyphs are 'egg-oriented' instead of writing holes. Though this 'school' is not consequent, as Ha5-53 and Qa5-44 shows.

As regards GD16 I earlier have tried to classify which variants appears in different texts. The result of this investigation is that what I above has called 'egg-orientation' (for H and Q) also clearly appears in GD16.

So this explains why Hb1-1 (see next page) and the parallel glyph in Q has only one rim, while the parallel glyph in P has two rims. The journey for the sun into (or out from) the underworld in P shows a watery hole, in H and Q perhaps a ship or a shield. A ship is neutral, but a shield would indicate 'summer' I think. A hole might be regarded as a sign for the underworld ('winter'), but limits belong to both sides.
