But before astrology fans scrape the ink from their arms because they think they're now a Virgo instead of a Libra, they should consider this: If they adhered to the tropical zodiac - which, if they're a Westerner, they probably did – absolutely nothing has changed for them.

They claim nothing has changed at all. Here is a deeper explanation a little further down.

That's because the tropical zodiac – which is fixed to seasons, and which Western astrology adheres to – differs from the sidereal zodiac – which is fixed to constellations and is followed more in the East, and is the type of zodiac to which the Star Tribune article ultimately refers.

And also, this controversy is nothing new according to these sources.

Two zodiacs. That's nothing new. "This story is born periodically as if someone has discovered some truth. It's not news," said Jeff Jawer, astrologer with Tarot.com.

So don't get that tattoo removed just yet!

Read that entire article it's quite interesting. It says that our "tropical" zodiac is fixed to the equinoxes and therefore does not alter due to axial tilt variations.

Also the sources claim that Ptolemy codified this particular flavor of zodiac in the 2nd century purposely to be based off the seasons, not based on constellations positions.

Sweet. Now I can dump my wife and tell her our signs are no longer compatible.

appreciate the information.
I was more interested in the actual shift then anything else.
