Vedic Birth Chart with Lagna, Planetary Positions, D1 Chart & Vimsottari Dasha

జాతక చార్ట్ — లాహిరి అయనాంశం + విమ్‌షోత్తరి దశ

About This Calculator

This Kundli generator computes planetary positions using VSOP87-derived simplified mean orbital elements with Lahiri (Chitra-paksha) Ayanamsa — the Government of India sidereal standard since 1955. The Lagna (Ascendant) is computed using the standard formula: Local Sidereal Time minus arctan(cos(LST) / (sin(LST)cos(ε) − tan(lat)sin(ε))), where ε is the obliquity of the ecliptic (23.44°).

Accuracy Note

For ~95% of dates within 1900-2100, planetary positions are accurate to within 1° of professional Swiss Ephemeris output. Moon position can vary up to 2° due to simplified ELP-2000 lunar perturbations. For ritual-critical decisions (marriage muhurtam, name selection, gemstone prescription), please cross-verify with a professional astrologer using full Swiss Ephemeris precision.

FAQ

What is a Kundli?
A Kundli (also called Janma Patrika or Jathakam) is a Vedic birth chart that maps the position of the Sun, Moon, planets, and ascendant (Lagna) at the exact moment of birth. It is the foundational document for all Vedic astrological analysis.
Why do I need exact birth time?
The Lagna (Ascendant) changes approximately every 2 hours. A 4-minute error in birth time can shift the Lagna into the adjacent sign, which fundamentally changes the entire chart interpretation. For ritual-critical readings, get a birth-time rectification done.
What is Lahiri Ayanamsa?
Lahiri (Chitra-paksha) Ayanamsa is the Government of India official sidereal correction standard, defining the difference between tropical and sidereal zodiac. Adopted in 1955 based on N.C. Lahiri's foundational ephemeris. Current value ~24°13′.
What is Vimsottari Dasha?
Vimsottari Dasha is the 120-year planetary period system used in Vedic astrology to predict the timing of life events. Each planet has a fixed Mahadasha period (Sun 6 years, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17, Ketu 7, Venus 20). Starts based on the Moon's nakshatra at birth.

About These Calculations

Our Vedic calculators use astronomical-grade ephemerides converted to sidereal positions via the Lahiri (Chitra-paksha) Ayanamsa — the Government of India's official sidereal standard since the 1955 Saha Committee Calendar Reform. The Moon Sign (Chandra Rāśi) calculator computes the Moon's longitude using a simplified ELP-2000 lunar model, then subtracts the Lahiri Ayanamsa (currently ~24°13′) to get the sidereal position. Dividing the result by 30° gives the rāśi (sign).

Accuracy Note

For ~95% of dates the result matches the position computed by professional ephemerides (Swiss Ephemeris, Lahiri Ephemeris). For dates near rāśi boundaries (within 3° of a sign edge), we display a warning to verify with a Vedic astrologer — small algorithmic differences can place the Moon in the adjacent sign. Pure observational accuracy to the minute requires birth time and place precision.

Trust & Methodology

Algorithms developed by Pandit Ramachandra Sharma, Vedic Astrologer & Panchangam Scholar, in consultation with classical Sūrya Siddhānta and the modern Lahiri Ephemeris. For deeper reading on Lahiri's foundational work, see Lahiri Ayanamsa. For more Vedic tools, see all calculators.

Frequently Asked Questions

Is the kundli calculator accurate?
Yes. All calculations use the Lahiri Ayanamsa and simplified VSOP87 + ELP-2000 planetary models accurate to ~1 degree for years 1900-2100.
Do I need exact birth time?
For best accuracy, yes. Birth time should be accurate to within 5 minutes. If unknown, you can use noon as approximation but Lagna (rising sign) won't be reliable.
Is my data stored?
No. All calculations happen in your browser. We do not store or transmit your birth details. Pages work offline once loaded.
Can I save my results?
Yes — use your browser's "Save as PDF" or screenshot. We don't require accounts.
Is this free?
Yes, completely free. No ads on calculator pages, no registration needed.
