In 20 days the North and South poles turn through the circle of illumination thereby dividing the day part from the night part of the polar cycle for each respective polar location. The revised values given for the relationship between the polar points and the circle of illumination are based on the distance the North/South poles turn across the fully illuminated face of the planet. In much the same way all locations turn through a distance when it exits the circle of illumination (sunrise) to re-entering it (sunset) as a function of daily rotation, the orbital surface rotation can be treated in much the same way although just as interesting for the differences involved in variable orbital speed.

The entire surface of the Earth turns, on average, about 60.97 miles per day and parallel to the ecliptic as a function of the planet's orbital motion so currently the polar points are roughly 1,219 miles from the circle of illumination. The day part of the cycle in the Southern hemisphere is coming to an end while the Northern hemisphere the day part is about to begin as polar dawn is now well established in the Northern polar latitude.

What can be said for a community who vacillate between a tilting Earth and a pivoting circle of illumination but that is altogether a different story.
