This new and productive area of research which combines humans to the two surface rotations by way of two internal body clocks is not going to be dragged back by celestial sphere enthusiasts nor by the recent upstarts who conjured up the idea that the Earth turned once in 24 hours but only back in 1820. Any person who occupies themselves with such notions automatically excludes themselves from either the astronomical aspect or the human one.

Insights are absorbed nowadays so that innovations like the partitioning of the inner and outer planets by perspective seen from a moving Earth was rapidly adopted where relative speeds govern the perspective for an outer planet (now a relative term) while inner planets simply are seen to run their circuits with little input from the slower moving Earth.

The explanation of the polar day/night cycle exclusive to the weekday rotation naturally correlates with the body clock of dormancy and activity but the annual cycle is far more subtle than the 24 hour cycle. Of course only those who live in those latitudinal bands where the annual cycle is more pronounced will have a sense of the impact but many older people put it in perspective by telling me they prefer Easter to Christmas when the first signs of a rejuvenated nature start to appear, for me it is the first shoots of daffodils around mid-February coinciding with the 6 Nations rugby tournament.
