Time and timekeeping

Celestial sphere ideology is always the same, it assigns relevance to
circumpolar motion and models the motions of the Earth on the assertions even
though they defy experience.

Yes, the movement of the stars around Polaris is certainly not as relevant to
the experience of our daily lives as the 24 hour cycle of night and day.

But just as the distinction between Ptolemy and Copernicus isn't evident in
normal experience, why should the physical dynamics of the Earth be in our
ordinary experience either? The Earth beneath my feet doesn't feel like it's
moving at over 1,000 miles per hour!

The Sun's apparent motion in the sky is subject to the Equation of Time, but
stellar circumpolar motion is even and regular. So it is the latter that is a
simple motion - and the former is a compound motion. The Equation of Time tells
us that about the apparent Sun just as retrogrades tell us that about the
apparent motions of the planets.

They don't even do this anymore as they conjured up a new proposal that the Earth
turned 360 degrees in 24 hours but back in the year 1820 as the website Martin
Brown referenced.

No, you're just drawing an unwarranted conclusion from an oversimplification.
