How Kundli.io Calculates Your Birth Chart
We reject "black-box" predictions. We provide explainable calculations by separating mathematical astronomy from traditional interpretive frameworks.
Astronomical Calculation
The calculation of planetary coordinates, ascendant degrees, house cusps, and divisional charts is purely astronomical and mathematical.
- ✓ Swiss Ephemeris high-precision planetary positions
- ✓ Precise Sidereal conversion with Lahiri Ayanamsa
- ✓ Exact geodetic latitude/longitude topocentric calculations
Astrological Interpretation
The interpretation of those calculated positions follows classical Vedic Jyotish literature (such as the Brihat Parashara Hora Shastra).
- ✓ Traditional house lords, Nakshatra deities, and Karakas
- ✓ Contextual guidance rather than deterministic prophecies
- ✓ Grounded self-reflection without superstitious fear
1. High-Precision Ephemeris
We compute raw celestial coordinates using the Swiss Ephemeris algorithm (the gold standard in astronomical calculation), achieving sub-arc-minute precision.
2. Lahiri Ayanamsa Correction
Because the Earth's rotational axis wobbles (precession of the equinoxes), we subtract the official Lahiri (Chitra Paksha) Ayanamsa to map tropical positions into the true Sidereal (Nirayana) zodiac.
3. Ascendant & Whole Sign Bhavas
Based on geographic latitude, longitude, and local sidereal time, the exact rising sign (Lagna) is determined. Houses are organized using classical Vedic Whole Sign principles.
4. Divisional Charts (Vargas)
Planetary longitudes are mathematically divided into harmonic Vargas: D9 (Navamsa) for internal disposition and marriage, D10 (Dashamsha) for career, and D7 for progeny.
5. Vimshottari Dasha Cycles
The Moon's exact degree in its Nakshatra determines the starting balance of the 120-year Vimshottari cycle, mapping out sequential Mahadashas and Antardashas.
6. Objective Dosha Cancellation
Instead of simplistic flag-setting, we apply classical Parashari cancellation rules (Nivarana) to verify whether afflictions like Mangal Dosha are cancelled by placement or aspect.
Why Birth Time Precision Matters
Because the Earth rotates 360 degrees every 24 hours, the Ascendant (Lagna) advances approximately one degree every 4 minutes. An inaccurate birth time can place the Ascendant or divisional chart into an adjacent sign. For maximum accuracy, always use the birth time recorded on official birth documentation.

Classical Ashtakoota Milan With Objective Dosha Checks
Rather than an oversimplified yes/no score, Kundli.io evaluates all 8 Kootas (36 Gunas) covering temperament (Gana), mental harmony (Maitri), longevity (Tara), and health (Nadi), paired with automatic Mangal Dosha cancellation logic.
The 8 Kootas Evaluated
Classical Mangal Dosha Cancellation Rules
Classical texts outline numerous conditions where Mangal Dosha is considered neutralized (Dosha Nivarana):
- Mutual Placement: If both prospective partners are Manglik, the dosha is traditionally considered cancelled.
- Dignity in Sva-Rashi / Uchcha: When Mars sits in its own signs (Aries, Scorpio) or exalted sign (Capricorn), its negative manifestation is said to be subdued.
- Jupiter Aspect: An aspect from benefic Jupiter on Mars provides natural mitigation.
Zero Fear-Mongering. Transparent Cancellation Logic.
Many online platforms use Mangal Dosha or Kaal Sarp Yog to cause distress. At Kundli.io, every dosha is checked objectively using classical cancellation exceptions from the Parashari system.
Divisional Charts (Vargas)
A Rashi chart (D1) only tells part of the story. Kundli.io computes the essential divisional harmonics: D9 Navamsa for marital destiny and inner strength, D10 Dashamsha for career vocation, and D7 Saptamsha.
Vimshottari Dasha System
The 120-year Vimshottari cycle is computed from the exact longitude of the Moon at birth. Understand which planetary energy governs your current period (Mahadasha) and sub-period (Antardasha).

Frequently Asked Questions
A Janam Kundli (Vedic birth chart) is an astronomical snapshot of celestial planetary positions at the exact moment and geographical location of your birth, plotted into 12 houses (Bhavas) and signs (Rashis) following classical Vedic astrology principles.
Kundli.io uses a two-phase engine: First, it computes high-precision astronomical coordinates of the Sun, Moon, and planets using the Swiss Ephemeris algorithm. Second, it applies the Lahiri Ayanamsa to map those coordinates into the true Sidereal (Nirayana) zodiac and organizes the houses using Whole Sign principles from classical Vedic texts.
We strictly use the Lahiri Ayanamsa (Chitra Paksha), which is the official standard adopted by the Government of India Calendar Reform Committee and respected by traditional Vedic astrologers worldwide.
Yes. Kundli.io uses the Sidereal (Nirayana) zodiac exclusively. Unlike Western Tropical astrology which ties signs to seasons, Vedic astrology measures against the actual fixed astronomical constellations in the sky.
Swiss Ephemeris is a high-precision software library developed by Astrodienst, based on NASA Jet Propulsion Laboratory (JPL) planetary and lunar ephemerides. It is widely considered the gold standard for astronomical coordinate computation.
You need three details: Date of Birth, exact Time of Birth, and Place of Birth. Time accuracy is essential because the Ascendant (Lagna) sign shifts approximately every 2 hours (1 degree every 4 minutes).
No. Your birth details are processed completely in-memory to generate the report and are never permanently stored in a database, sold, or shared with third parties. Zero retention is a foundational privacy principle of our architecture.
The ₹99 report includes: Lagna Chart (D1), Navamsa Chart (D9), Dashamsha Chart (D10), Saptamsha Chart (D7), exact planetary degrees and retrograde status, full Vimshottari Dasha timeline, Mangal Dosha analysis with cancellation check, Kaal Sarp Dosha check, house lord interpretations, and an instant downloadable PDF.
Kundli Matching is the traditional Vedic method for assessing marriage compatibility using the Ashtakoota system (36 Gunas). It analyzes temperament (Gana), psychological friendship (Maitri), longevity (Tara), sexual compatibility (Yoni), and physiological health (Nadi), paired with mutual Mangal Dosha analysis.
Mangal Dosha occurs when Mars is placed in houses 1, 4, 7, 8, or 12. However, classical Jyotish defines numerous cancellation rules (Nivarana) — such as Mars being in Aries, Scorpio, or Capricorn, or aspected by Jupiter. Our platform evaluates these classical cancellation rules transparently rather than presenting an alarming generic prediction.
Divisional charts are harmonic sub-divisions of the 360° zodiac. The most critical is the D9 (Navamsa), which reveals inner potential and marriage destiny, and the D10 (Dashamsha), which indicates career inclination and professional success.
Vimshottari Dasha is a 120-year planetary cycle system in Vedic astrology. Starting from the exact degree of the Moon in its birth Nakshatra, it identifies which planet's influence governs each period (Mahadasha) and sub-period (Antardasha) of life.
