Then we chose a point that doesn’t line up with either the apsides or the solstices to represent “zero” and sticking with our mistake for primitive reasons like “tradition”.
We stick with it at this point because it’s not worth the hassle of changing it, and while points related to our axial tilt or the eccentricity of our orbit are less arbitrary it ultimately doesn’t matter. It is about the time that has passed and one point in the orbit is as good as another.
