A birth chart is a precise astronomical snapshot of the sky at the exact moment and location you were born. It records the longitude of every visible planet — Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn — along with the shadow points Rahu and Ketu, and maps them onto twelve houses and twelve signs. Each planet carries specific significations: the Sun governs vitality and authority, the Moon shapes emotional temperament, Mars fuels ambition and courage, and so on through the entire nine-body system used in Vedic tradition.

The twelve houses of the birth chart divide life into concrete domains — personality, wealth, siblings, home, children, health, partnerships, transformation, fortune, career, gains, and liberation. When a planet occupies or aspects a house, it colors that area of life with its own nature. A strong Jupiter sitting in the ninth house, for example, amplifies luck and higher learning, while Saturn in the seventh may signal delayed but enduring partnerships. By reading these combinations together, the birth chart becomes a layered portrait of temperament, talents, challenges, and timing that no single sign or planet can provide on its own.

Using the tool is straightforward: enter your date of birth, the time you were born (as accurately as possible), and your birth location. The engine converts your geographic coordinates into the local sidereal time, calculates the ascending degree on the eastern horizon, and places all nine Vedic planets in their true sidereal longitudes using the Lahiri ayanamsa. Within seconds you receive a fully rendered South Indian or North Indian style chart along with detailed tables of planetary degrees, house cusps, and dignities.

Beyond the raw chart, the tool automatically scans for over 470 classical planetary combinations (yogas) documented in texts like Brihat Parashara Hora Shastra and Phaladeepika. Each detected yoga is displayed with its traditional name, the planets and houses involved, and a plain-language explanation of its effect on your life. An integrated AI chat lets you ask follow-up questions about any part of the chart, so you can move from data to understanding without leaving the page.

Start with the Ascendant (Lagna), the sign rising on the eastern horizon at your birth moment. It sets the framework for the entire chart: the first house begins here, and every subsequent house follows in zodiacal order. Your ascendant lord — the planet that rules your rising sign — acts as the chart's chief narrator, and its house placement, sign dignity, and aspects tell you the overarching theme of your life direction.

Next, review the Strength Chart section. VedAstro calculates Shadbala (six-fold strength) for each planet, giving you a numeric score that shows whether a planet is powerful enough to deliver its promises or too weak to act. Planets with high Shadbala in favorable houses amplify positive yogas; those with low scores may indicate areas that require conscious effort. The Ashtakvarga table adds another layer by scoring each planet's transit strength across all twelve signs, helping you anticipate which future transits will be supportive and which ones call for caution.

Finally, explore the AI Chat feature built into the results panel. After your birth chart is generated, you can ask the AI astrologer specific questions — "What does my Moon in the fourth house mean for family life?" or "Which dasa period is most favorable for career growth?" The AI draws on the same classical rule base used to detect yogas and combines it with your unique chart data to give contextual, personalized answers rather than generic descriptions.
