How does geocentrism explain claims that the earth once rotated faster, giving a 360-day year?

Geocentrism explains it by saying the sidereal rotation has always been the same since the earth was created and has not changed; it is 23 hours, 56 minutes, and 4.09 seconds. The so-called 360-day calendar was introduced for other reasons, not because anyone knew the earth or sky could rotate faster or slower. In the heliocentric system, where everything depends on the earth's spin, the rotation could change, because things like the moon receding a few centimeters a year could, over long ages, affect it. But in the geocentric system the earth is not rotating; the universe is rotating, and whatever happens to the earth and moon does not change the rotation of the universe, so sidereal time stays the same. This is why I teach that God did not make the universe with the earth rotating: to keep time with a rotating earth, in the midst of the millions of earthquakes, volcanoes, tides, and gravitational effects every year that would slow it down, would be impossible, and if the earth slowed you would get too much sun on it and burn up all the vegetation. The universe's rotation around the fixed earth is what makes the calendar, precisely 365.25 days, and it never needs adjustment.
