Well, sort of. Astrology predicts that you have traits or characteristics that are determined by the time of your birth within the year. It has been shown that your chances of being autistic are greater if you are conceived in winter (http://medicalxpress.com/news/2011-05-children-winter-greater-autism.html). If winter means the coldest months (Dec, Jan, Feb in the Northern hemisphere), then add 9 months and you find that Libra, Scorpio, and Sagittarius should be the most common signs for autistic children.
What about other mystical dates and times? The students of Tweed Jacket (what I call myself in my role as a Professor of Computer Science) are receiving their final examination on Friday the 13th this year. I am predicting they will not be lucky.
