I think it is a mixture between bending, hanga, GD36 and GD24.

In the calendar of the day we can see the sun being born through the upper hole, therefore the lower hole must be the hole for dying. This, then explains why GD24 is found in Saturday. Saturn is Time, the devourer of all living things.

The holes are closed in the glyph we have here. Seems reasonable as we are in the middle of the sky.
