Astrology is based on what constellation the sun was in at the time of your birth. One thing it doesn't take into account is precession. The Earth actually wobbles a bit, like a spinning top that is slowing down. OK, so it takes 25,800 years each wobble, but it's still there. Have you ever heard that Polaris wasn't the north star when the pyramids were built? Same idea. Precession causes the date that the sun is at a particular point in the Zodiac to slip about one day every 70 years.
Another problem is that all of the zodiacal constellations aren't the same size. There's also a 13th one, Ophiucus, which isn't even recognized by astrologers. Here's a table that explains things better:

In short, astrology is all a bunch of hooey!

All this time I thought I was an Aries, but I'm really a Pisces! HA!
