Personally, I've never had much interest in astrology and horoscope signs but there's quite a hubbub among my Facebook friends (and the rest of the internet) right now about whether there's been a historical misreading of the astrological calendar and a shift in dates associated with different signs. Wait...so I'm not a Libra anymore? And what's this about a 13th sign?
Why this topic is having its 15 seconds right now is not entirely clear. A quick search came up with an article on this idea on Live Science (filed under "Strange News") from 2007. But, hey, who am I to argue with the forces of the internet!
Rather than try to explain the brouhaha here, I'll point you toward these articles:
• Your Astrological Sign May Not Be What You Think It Is (Live Science)
• No, Your Zodiac sign hasn't changed (CNN.com)
• There really is a 13th zodiac sign named "Ophiuchus" that you've probably never heard of (Dictionary.com - I know, it seems like a strange source to cite, but I'm a big fan of "the Hot Word" feature every day)
