What Is a Vedic Birth Chart and What Does It Reveal?
A Vedic birth chart — called a Kundali or Janma Patrika in Sanskrit — is a precise map of the sky at the exact moment and location of your birth. Unlike a generic horoscope written for an entire Sun sign, your Kundali is unique to you: it records the positions of the Sun, Moon, and all eight planets across twelve houses, using the sidereal zodiac corrected by the Lahiri Ayanamsa — the standard adopted by the Government of India since 1955.
The sidereal zodiac tracks the actual positions of planets against the fixed stars, rather than the seasonal tropical zodiac used in Western astrology. Due to the slow precession of the equinoxes, the two systems are currently about 23–24 degrees apart — which is why your Vedic Sun sign is often one sign earlier than your Western Sun sign. This is not an error; it is a fundamental difference in astronomical reference frame.
What Your Birth Chart Contains
A complete Vedic birth chart analysis covers several interconnected layers:
The Ascendant (Lagna) is the zodiac sign rising on the eastern horizon at your birth. It governs your outward personality, physical constitution, and the lens through which you experience the world. The Ascendant is the most personalised point in your chart — it changes roughly every two hours, making birth time precision essential.
Planetary positions and Shadbala — each planet occupies a house and a sign, and its strength is measured through the classical Shadbala (six-fold strength) system, which scores planets across positional, directional, temporal, motional, and aspectual dimensions. A strong planet in your chart amplifies the themes of the house it rules; a weak planet may indicate areas requiring conscious effort.
Classical Yogas are planetary combinations described in classical Jyotish texts such as Brihat Parashara Hora Shastra. Certain combinations — like Raj Yoga (combinations for authority and success) or Dhana Yoga (combinations for wealth) — indicate specific life themes and potentials. A proper birth chart analysis identifies which Yogas are present and how strongly they are activated.
The Vimshottari Dasha timeline is the primary predictive tool in Vedic astrology. It is a 120-year cycle of planetary periods (Mahadashas) determined by the Moon's Nakshatra at birth. Each Mahadasha lasts between 6 and 20 years and is governed by a specific planet, shaping the dominant themes of that life chapter. Within each Mahadasha are Antardashas (sub-periods) that refine the timing further. Knowing your current Dasha period is essential for understanding which life themes are active right now.
The Nakshatra profile — your Moon's Nakshatra (birth star) is one of 27 lunar mansions, each with a ruling planet, deity, symbol, and archetypal quality. The Nakshatra adds a layer of nuance to your Moon sign, shaping your emotional instincts, relational style, and karmic tendencies in ways that the sign alone cannot capture.
How TealChart Calculates Your Birth Chart
TealChart uses Swiss Ephemeris 2.10 — the same astronomical library used by professional Jyotish practitioners and academic researchers — to calculate all planetary positions to sub-arcsecond accuracy (0.001 arc-second), based on NASA JPL DE431 planetary data. Your birth location is geocoded via OpenStreetMap Nominatim to obtain precise latitude and longitude coordinates.
The result is a 35–40 page personalised PDF report, written in second-person narrative prose and structured for readability by non-astrologers. It includes a Quick Reference card summary, core analysis sections covering character, relationships, career, and life-arc themes, a Vimshottari Dasha timeline, and technical annexes with planetary position tables and Yoga identification.
