Okay, this is just wrong. We’ve gone thousands of years without changing anything, now this? What’s next? A 13th month?
But leading astrological experts say this won’t change things at all. That’s because Western astrology strictly adheres to the tropical zodiac, which is fixed to seasons. The sidereal zodiac, observed in the East, is the one affixed to constellations, and is thus the one that would change. The tropical zodiac has been in place since Ptolemy’s in the second century..
So, who’s right? Who cares! I’m just glad that I’m still living in the Age of Aquarius, and will be til the day I leave this life.
