You are still a "Libra". That is because Western astrological zodiac signs are NOT based on the stars, but on the seasons. Nothing has change.
A "zodiac" is a man-made system.
There are three MAJOR zodiac systems, and many more than that.
The one that NASA has is the scientific zodiac system.
The one that Western astrologers use is the Tropical zodiac system.
The one that Hindu/Vedic astrologers use is the Sidereal zodiac system.
All 3 of these are different.
The one that you have heard about that has undergone changes is the scientific zodiac system.
This has nothing to do with astrology, and there are no changes in astrology.
Some stupid reporters (and some people who have websites who do NOT understand astrologer) mistakenly think there is only one zodiac system.
