And their satellites, obviously.  Things could become pretty messy in
binary star systems, too.  Think of a satellite on a retrograde orbit
(like Triton) around a heavy planet (like Neptune) that is in forward
rotation around the center of gravity of a binary star system...

Don't forget the hemispheres and that seasons depend on latitude.  For
example, between -15 and +15 degrees on Earth there is only one
season; between 15 and 35 degrees, two seasons (dry and wet); between
35 and 72 degrees, four; above 72, two again (day and night).

Also, on some planets (e.g. Mars), the four seasons have different
lengths due to the eccentricity of the orbit.

We need an AI for that...
