Just a heads up...the 13th sign always existed just that astrologers in all their wisdom decided 12 signs were purdier! And also they change regularly bc the Earth rotates on a pernumbrum and is not straight so the dates have changed drastically over the 2000 years since the signs were all started. So you were always a different sign..although this all just really proves what a bunch of hooey astrology really is! Whatever sign you were before everyone was able to relate to and say that their characteristics were really like that! o well now guess what?! you weren't always that sign anyway...hmm...maybe just a bunch of general traits that one could pretty much assign to anyone easily...
