Midseason autumnal equinox

So on Saturday September 23rd at 04:03 a.m. (or Friday night at 9:03 p.m. for me in the Pacific time zone) the Sun will cross from the northern celestial hemisphere to the southern one, and most people will say it's the start of autumn in the northern hemisphere.

I don't say that, I say it's the middle of autumn. But I have to explain this four times every fracking year, so instead of saying it again I'll just point you to the blog entry I wrote in the spring about seasons and equinoxes and eggs.

Tip o' the artist's beret to BABloggee Steve Kluge for the great diagram!
