If you imagine the sun moving around the earth 180 degrees and earth flowing into a counter orbit of the sun; to calculate the amount the earth must twist (on the vertical axis pointing to the ecliptic pole in the heart of the Dragon Constellation) to keep the same season on earth:
Determine the date, then count the number of days:
March 21 backwards to December 21 (the spring equinox backwards to the winter solstice), then replace the ? in this formula: -(?/90)*180. The spring equinox 1238 BC was April 2, 2357 BC April 10, 3637 BC April 21, Julian, so adjust your calculations accordingly:
March 21 - June 21, (?/90)*180
September 21 backwards to June 21, -(?/90)*180
September 21 - December 21, (?/90)*180
Just count the days in the season selected and multiply by 2. If the miracle happened in our counterclockwise orbit, the - sign denotes the degrees of twist clockwise, no sign denotes the degrees of twist counterclockwise. Likewise, assuming a clockwise orbit, - sign denotes the degrees of twist counterclockwise, no sign denotes the degrees of twist clockwise.
There is no evidence of such magnetic alignments of ocean floor magmas at the time they cooled. However, short term tilts would not have had time to leave their evidence. Also, this twist is about the ecliptic pole, meaning the magnetic pole may not have moved.
