On '12'-'28' of any 2-D calendar year, the axial geometry of this Earth is set to be adjusted from ~23.5° to ~98.0° over the course of one planetary rotation, moving this planet beyond the Holocene while also causing the Sun to appear to rise from the western horizon worldwide when viewed from the surface of this planet. Additionally, the plane of this star system is set for adjustment matching the plane of this galaxy.

Both adjustments will cause major+minor changes to this star system+planet+species+civilization.
