Tamil Jyotisha Explorer

Study the traditional South Indian Vedic chart alongside your Yoga practice. Enter a birth date, time and place — the tool computes the Sidereal Rasi Chakra (D1), Navamsa (D9), Nakshatra, Lagnam, Vimshottari Dasha and classical Doshas — live in your browser.

Educational study tool — not a prediction or diagnosis

This page is provided for educational purposes only. Jyotisha (Vedic astrology) is one of the six Vedangas — the classical companion disciplines to the Vedas — alongside Yoga, Nirukta, Chandas, Vyakarana and Kalpa. Traditionally, students of Yoga study Jyotisha to understand the cosmological framework their practice sits within.

The results shown here are traditional interpretations drawn from classical Tamil astrological texts. They are not medical, financial, legal, or life advice, and are not a substitute for professional consultation. For matters requiring precise computation (muhurta, marriage matching, remedial rituals), please consult a qualified Jyotisha professional with proper Swiss Ephemeris software.

Accuracy note: planetary, Sun and Moon positions are computed with the high-precision, MIT-licensed astronomy-engine library (JPL-grade) running entirely in your browser, then converted to sidereal with the Lahiri ayanamsha. Its geocentric longitudes have been validated against Swiss Ephemeris reference calculations and agree to within about 7 arc-seconds (≈0.12 arc-minutes) for the Sun, Moon and the five visible planets across 1950–2036 — far finer than any nakshatra or sign boundary. Rasi (Moon sign) and Nakshatra placements are reliable across many centuries — these are the primary values of a Vedic chart. The Lagnam (Ascendant) remains sensitive to birth-time precision and can differ by up to one sign at borderlines: if your Lagnam matters for a specific decision, confirm your exact birth time. Borderline nakshatra results (within the last or first pada) should likewise be treated as guidance.

🕉 About Jyotisha — the Sixth Vedanga, Companion to Yoga

In the classical Indian curriculum, the six Vedangas ("limbs of the Veda") were studied together as one integrated discipline. A yoga student was expected to learn:

  • Shiksha — pronunciation and phonetics of the sacred texts
  • Chandas — poetic meter
  • Vyakarana — grammar and language structure
  • Nirukta — etymology and the meaning of words
  • Kalpa — ritual procedure and code of conduct
  • Jyotisha — the study of celestial cycles and time

Jyotisha (from Sanskrit jyoti = light, isha = lord — "the science of light") teaches a yogi to understand time. When is the auspicious hour for practice? When does the season shift? Which lunar phase best supports pranayama, and which supports rest? These questions cannot be answered by asana alone — they require the sky.

This is why every classical yoga lineage — Patanjali, Iyengar, Vethathiri Maharishi, Bihar School — teaches its senior students at least the basics of Jyotisha. The Nakshatra you were born under, your Rasi (Moon sign) and your Lagnam (rising sign) are considered part of understanding where in nature you stand.

SEGA offers this tool so students of Yoga in the alliance can explore that framework in one click, side by side with their asana and pranayama practice — without needing to leave for a third-party astrology site. All computation happens in your browser; no birth data ever leaves your device.

How much do you know?
⚙ Automatic Historical Timezone Correction

Leave this alone unless your chart disagrees with a jathagam you hold. By default the chart uses the standard offset your city keeps — which is how nearly every printed jathagam and every other piece of software computes it, so your lagnam here should match the one you already have.

There is a second, stricter answer. Clocks move: peninsular Malaysia kept UTC+7:30 until 1 January 1982 before changing to +8, India ran on other offsets before 1955, and many US and European dates fall inside daylight-saving changes. Half an hour of clock is 7.5° of ascendant — enough to move your lagnam into the next sign. Ticking the box below computes from the offset that was actually in force on your birth date.

Neither is a trick answer. If the two give you different lagnas, the career reading will show you both side by side whichever you pick — and if you already know your lagnam, say so in the box below and the engine will rectify to it instead.

☊ Lunar node (Rahu / Ketu)

Most Vedic software uses the Mean Node. The True (osculating) Node reflects the Moon's instantaneous orbital node and can differ from the mean position by up to ~1.5°. Recompute the chart to apply your choice.

⚖ Do you already know your Lagnam?

If you hold a family jathagam or a reading you trust, say which lagnam it gives. The ascendant moves a degree every four minutes, so a birth time written down as a round number is often a few minutes out — and those few minutes are the whole difference. Name your lagnam and the engine will find the nearest birth time within ninety minutes that produces it, use that, and tell you exactly how far it moved. That is rectification, and it is what you would otherwise be doing by hand.

🔒 Your birth data never leaves this browser. Everything is computed on your own device — nothing is sent to SEGA or any third party.
