TomrosVedic Astrology Calc

Vedic Astrology Calc

Vedic astrology (Jyotish) uses the sidereal zodiac, aligned with the fixed stars, so planets usually sit in a different sign from Western charts. Enter your birth details to see your Lagna (ascendant), the rashi, nakshatra and pada of every graha and a South Indian chart. The positions are computed in your browser with standard astronomical approximations.

Sidereal vs tropical zodiac

Western (tropical) astrology fixes 0° Aries at the March equinox. Vedic astrology uses the sidereal zodiac, fixed against the stars. Because the equinox slowly drifts backwards through the constellations (precession), the two zodiacs are now about 24° apart. That difference is the ayanamsa: sidereal longitude = tropical longitude − ayanamsa. Lahiri (Chitrapaksha), the ayanamsa adopted officially in India, is the default; Raman and Krishnamurti (KP) are popular alternatives that differ by up to about 1.5°.

Worked example

For a birth on 15 January 1990 at 06:30 IST (UTC+5:30) in New Delhi (28.61° N, 77.21° E) with Lahiri ayanamsa, the calculator places the Lagna in Dhanu at about 18°21′, the Sun in Makara and the Moon in Simha at about 18°00′, in Purva Phalguni nakshatra, pada 2. Rahu is in Makara and Ketu opposite in Karka. Change the birth time by 20 minutes and the Lagna degree moves by roughly 5°, which is why an accurate birth time matters.

South Indian and North Indian charts

Both chart styles show the same information. In the South Indian chart, used above, the signs stay in fixed boxes — Pisces at the top-left, then Aries, Taurus and Gemini across the top, continuing clockwise — and the Lagna is marked with a diagonal line. In the North Indian chart the houses are fixed instead: the top centre diamond is always the first house, and the sign numbers change with the Lagna. The template pack includes blank versions of both.

About Jyotish

Jyotish is a traditional system with a long history in South Asia and is used by many families for naming, muhurta (timing) and life events. Its astronomical calculations are real; its interpretations are a matter of cultural tradition and personal belief rather than scientific evidence. For readings, consult a practitioner you trust.
