Hello Sophia, I appreciate your question, as per my knowledge Yes, the 12 zodiac signs are the same in both systems (Aries, Taurus, Gemini, etc.). The key difference: They calculate the signs differently. Western astrology is based on the seasons, while Vedic astrology is based on the actual star constellations (Nakshatra). Because of this, your sun sign in Vedic astrology is often different (usually one sign back) from your Western sun sign.
