Understanding Vedic Birth Chart Calculator

A Vedic birth chart, called a kundali or janma kundali in Sanskrit, is a map of the sky at the exact moment of your birth, viewed from your birthplace. It shows all nine classical Vedic planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu) distributed across twelve houses and twelve signs of the sidereal zodiac.

The sidereal zodiac is fixed against the backdrop of actual stars rather than tied to the seasons, as in Western astrology. The Lahiri ayanamsa correction, approximately 23°51' in 2024, converts tropical planetary positions to their true sidereal positions. This is why your Vedic Sun sign is typically one sign earlier than your Western sign.

Stellr's birth chart calculator uses the Swiss Ephemeris DE431 dataset with the Lahiri ayanamsa. In addition to the primary D1 (Rasi) chart, the engine computes 20 named divisional charts: D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D16, D20, D24, D27, D30, D40, D45, and D60. These include Navamsa (D9) for relationships and dharma, Dashamsa (D10) for career, Saptamsa (D7) for children, and Ashtamsa (D8) for transformation and longevity themes. The result also includes the rising nakshatra and pada, Vimshottari dasha timing, yogas, graha drishti, house lords, and strength markers.

Common questions

What is a Vedic birth chart?

A Vedic birth chart (kundali) is a map of the sky at the exact moment of your birth, using the sidereal zodiac and Lahiri ayanamsa. It shows the positions of nine planets in twelve signs and twelve houses, revealing personality, life themes, strengths, challenges, and timing patterns.

How is Vedic astrology different from Western astrology?

Vedic astrology uses the sidereal zodiac (fixed against stars) rather than the tropical zodiac (season-based). Your Vedic sun sign is typically about 23–24 degrees earlier than your Western sign. Often placing it in the previous sign. Vedic astrology also emphasises the Moon sign and Nakshatra far more than the Sun sign.

What information do I need to calculate my birth chart?

You need your exact date of birth, time of birth (as precise as possible), and place of birth. Birth time is essential for calculating your ascendant (Lagna) and accurate house placements. A difference of two hours can shift the ascendant to the next sign.

How are chart positions calculated?

Stellr uses the Swiss Ephemeris DE431 dataset and Lahiri ayanamsa for high-precision sidereal positions. Exact birth time and location remain important for the Ascendant, houses, and divisional charts.

What does my ascendant (Lagna) mean?

Your ascendant is the zodiac sign rising on the eastern horizon at birth. It represents your physical body, outer personality, and how others perceive you. It sets the structure of all 12 houses in your chart and is the most personally specific point in the chart.

What are divisional charts (Vargas)?

Divisional charts are derived by dividing each zodiac sign into smaller segments and using each resulting placement as a focused lens. Stellr computes 20 supported Vargas, including D9 (Navamsa) for relationships and dharma, D10 (Dashamsa) for career, D7 (Saptamsa) for children, D8 (Ashtamsa) for transformation and longevity, plus D2, D3, D4, D5, D6, D11, D12, D16, D20, D24, D27, D30, D40, D45, and D60.

What is Vimshottari Dasha?

Vimshottari Dasha is a 120-year planetary period system that divides your life into major periods (Mahadashas) ruled by different planets. Each planet's period activates different life areas based on its chart placement. The current active dasha explains much about your present life themes.
