Did you look up your zodiac sign yourself after reading that article, or did you just read that it supposedly shifted?
Here's the thing: Yes, precession is real and yes, the constellations are in different positions in the sky than they were 2,000 years ago. But there's a crucial distinction that most articles don't explain properly. Astrology works with a *tropical* zodiac that's based on the seasons - not on the current positions of the constellations. Your Aries dates (roughly March 21 to April 19) are fixed to the spring equinox, not to where the Aries constellation actually stands right now. That might have been different thousands of years ago, but astrologically nothing has changed for you.
It was similar for me: I looked up the exact astronomical position of my constellation out of curiosity once - and yeah, it's in a completely different place in the sky than the classical boundaries would suggest. But my astrological zodiac sign remained just as valid as before. If you're interested in where your actual constellation is in the sky right now, that's cool astronomical info, but it has nothing to do with astrology. You're still an Aries astrologically if you were born during that time.
