What is the difference between Vedic and Western astrology?

Western astrology uses the tropical zodiac, fixed to the seasons. Vedic (sidereal) astrology uses the fixed stars, which are about 24 degrees behind: so your Vedic sign is usually the one before your Western sign.

Why are my signs different?

The two systems measure from different points: the tropical zodiac starts at the spring equinox, the sidereal at a fixed star. The gap (ayanamsa) is about 24 degrees, roughly one sign, which shifts most people into the previous sign.

Western astrology reads the seasons; Vedic astrology reads the stars. Your sidereal sign is usually the one behind your tropical sign: find yours.

Tropical vs. sidereal

The two zodiacs start from different points. The tropical zodiac: used in most Western astrology: is anchored to the spring equinox, so it stays aligned with the seasons. The sidereal zodiac: used in Vedic astrology: is anchored to the fixed stars. Because the Earth's axis slowly shifts (precession), the sidereal sky is now about 24 degrees behind the tropical one. For most people, that moves the Sun into the previous sign.

The twelve signs

Aries (Fire · Mar 21 – Apr 19): The ram: initiative, courage, and the impulse to begin. Aries energy starts things and asks questions later.
Taurus (Earth · Apr 20 – May 20): The bull: steadiness, sensuality, and the slow wealth of persistence. Taurus builds what lasts.
Gemini (Air · May 21 – Jun 20): The twins: curiosity, communication, and the quick dance of ideas. Gemini sees both sides and says both aloud.
Cancer (Water · Jun 21 – Jul 22): The crab: feeling, home, and fierce protection of what is tender. Cancer carries a shell and a soft inside.
Leo (Fire · Jul 23 – Aug 22): The lion: warmth, creativity, and the need to be seen truly. Leo shines best when the light is shared.

Frequently asked questions

Is the Vedic sign calculation precise?

This calculator is approximate (to about a day). A precise sidereal chart requires your exact birth time and place, plus the ayanamsa used by your preferred tradition: the calculator gives you the right sign for most dates, with a note when you are near a cusp.

Which system is more accurate?

Neither is 'more accurate': they answer different questions. Tropical astrology reads your relationship to the seasons and life cycle; sidereal reads your relationship to the fixed sky. Many practitioners use both.
