The mea ke glyph type is associated with winter solstice, the time when sun has reached the deepest point in his yearly cycle.

It is illuminating to compare with the full moon glyph in the Mamari moon calendar:

Ca7-24	mea ke

At full moon a maximum of light has been reached, and then comes another 'season' when the sun light reflected from the moon is waning. At bottom inside the full moon oval waxing moon is seen at left and waning at right, the light from the sun 'staff' is broken at full moon.

In mea ke the 'broken' sign is at the top end of the glyph (and at the outside), and instead of a moon oval there is a henua sign. It means a maximum of darkness has been reached, in other words that the sun light is at its minimum.

An alternative interpretation of the K text.
