Yep, same here, simpliest I just did come by is, there is a plane perpendicular to orbit, which crosses centers of sun and earth, and then solstices is when the axis lays in the plane(angle between the plane and axis is 0), and equinoxes when it has max angle to the plane, which btw is tilt angle of the planet.

Forecast So it seems that getting the ecliptic longitude of the Sun would be the essential step, and then I could somehow solve that function for time: My first thought was to use something from scipy.optimize to solve this function for time, but at this point, I got stuck.
