I thought it would be interesting to see what the sky looked like on the night I was born. For years I've "known" I was born as a Cancer, my birthday being on July 8th.

Putting my birth date and approximate time into the Worldwide Telescope I can see clearly that the Sun was actually right in the middle of the constellation Gemini. Not on the edge between the two, but solidly in the middle of Gemini.

So what do the "classical" star signs mean? The answer can only be, nothing at all. If classical astrology is based on mystical associations between specific characteristics of celestial bodies, how can anyone be making valid associations if the underlying data us wrong???

Garbage in, garbage out.
