Webyou said that because the perihelion itself is changing, so it takes only 21000 instead of 26000yrs for earth's rotational axis to trace out a circle, then i will assume that the Axial Precession is calculated using the Sun as a frame of reference like you said.

When e = 0, the ellipse is a circle. The area of an ellipse is given by A = π a b, where b is half the short axis. If you know the axes of Earth’s orbit and the area Earth sweeps out in a given period of time, you can calculate the fraction of the year that has elapsed. grissani
