No longer can we avoid discussing the roles of the planets of the week. As a preliminary, but important, step I suggest the following wave-like pattern was in the mind of the designer of the week:

Instead of 'fire' and 'water' we could say e.g. 'high' and 'low'. The system of correspondences will also enable us to identify Sun, Mars, and Jupiter as 'male', while the other will be 'female' in character.

Saturn seems not to be a part of the game - which can be identified as the game of 'life' (i.e. light).

The wave crests are high up and the wave troughs are low down. A rhythm permeates living nature - ebb and high tide, growing and fading away, sun and stars, breathing in and breathing out, light and shadow. Without contrasts nothing would be discernible.

Of necessity the calendar makers (time keepers) must have tried to find the ups and downs in the flow of time. And they would seek to apply earlier successful such attempts to their new endeavours. The week was probably not the first such 'map'.

The birth of Sun we have found to be equal to the birth of the new year (beyond winter solstice). Moon (night) then seems to reign up to the arrival of spring light. The planet which brings the spring 'fire' is Mars. Mercury must be the planet who follows him, although not easy to perceive in the calendar course of the year (nor by observations in the sky).

If we begin our calendar with Venus (influenced by what we have read in H), then Saturn - who can be characterized as death personified - will be beyond Venus but before the arrival of the newborn Sun ('son' of the old Sun). Saturn is placed where sun is most faint and where he has stopped moving, and Saturn is indeed a very faint planet which moves only slowly - as if old - across the sky. We can therefore define our calendar as:

If we work with lunar months, a natural beginning for our calendar of the year would be for instance the day beyond day 354 (= 12 * 29.5). At that time the old year has gone away, which explains why suddenly a female in the night (Venus as evening star) is ruling. We can imagine that she in due time will give birth to next sun.

Jupiter will arrive 6 months beyond the end of the old year, 4 months beyond winter solstice. But presumably we instead ought to count in double-months, in which case Jupiter will come 8 months beyond winter solstice. That will put him in high summer where he belongs.
