Good stuff, Teg & Chalk!
I like to track moon phases for T2k so that I can give my players realistic info re natural lighting at night.

But what if it's cloudy, you ask? There are also historical weather sites.
AFAIK, this particular site provides historical weather data for Poland, but there's one for the USA as well (and probably other countries).
