Assuming that the time of year that you are born in has some affect on how you turn out, what do you think causes it? Is there any scientific explanation we could come up with that could explain the phenomenon? Or is the scientific view that there is no affect at all?
Perhaps the causation goes the other way. Personality traits are to some extent inherited. Perhaps fecundity and/or sex drive are somewhat seasonal. Then mating pairs of Homo sapiens (is this terminology getting you a little excited?) will tend to have offspring in certain months and pass on to them certain personality traits giving a zodiacal vs. personality trait correlation. As mentioned, one possible test for this would be Northern vs. Southern hemisphere comparisons. The biggest problem with all this is that determinations of personality are very subjective: have several friends write a description of what they think your personality characteristics are and include your own description and I suspect you will find a great diversity of opinion (and you might also find you have fewer friends than you thought). There are 'scientific' personality profile questionnaires, but I personally would have about as much faith in those as I have in astrology.
