Vedic astrology
Indian astrology measures the zodiac against the stars, not the seasons. Result: a shift of about 24°, which moves most people into another sign.
Why two zodiacs?
Western astrology starts Aries at the spring equinox: this is the tropical zodiac, tied to the seasons. Vedic astrology starts it against the fixed stars: this is the sidereal zodiac. The two drift apart by about 1° every 72 years; today the gap is 24.2° (Lahiri method).
