Which page is that Eroica? That url seems to point to the higher level frame. |

The zero point can be any date (like choosing the origin) but I think if you choose one of the solstices to be zero, then the other can not be. Still, even the analemma there seems to show the crossing to be off the zero axis.

You're right. I misread the curve. The other two points don't quite coincide with the solstices. The first one seems to be about a week before the Summer Solstice, and the later one is a few days after the Winter Solstice.
