The words janmakshar and jataka are region-specific terms for the same foundational concept in Vedic astrology: the birth horoscope. If you have heard a family say “send us the janmakshar” or “we need to see the jataka before we proceed,” they are asking for the birth chart — the astrological map of the sky at the moment of birth.
Janmakshar is primarily a Marathi and Gujarati term. Jataka is the term used in Kannada, Telugu, and some parts of Tamil Nadu. In Hindi and North Indian traditions, the same document is called the kundali or janam patrika. These are all the same thing — a Vedic birth horoscope.
What is a Janmakshar / Jataka?
A janmakshar or jataka is a document that records the astrological positions at the time of birth. A traditional Indian horoscope typically includes:
Lagna (Ascendant): The zodiac sign rising on the eastern horizon at birth. It defines the first house of the chart and is considered the most personal point.
Rashi (Moon sign): The zodiac sign occupied by the Moon at birth. This is the basis for most Vedic compatibility calculations.
Nakshatra (Birth Star): The specific lunar mansion (one of 27) where the Moon was placed at birth. This is the starting point for the Ashta Koota Guna Milan system.
Planetary positions: The positions of all 9 Grahas — Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu — in the 12 houses.
Dasha balance: The planetary period (Mahadasha) running at the time of birth, and the sequence of Dashas that will follow.
Jataka Matching for Marriage — How It Works
Jataka matching for marriage in the Vedic tradition follows the same core process regardless of regional terminology:
Step 1: Prepare both jaatakas. The bride’s and groom’s complete birth horoscopes are prepared — either by a Jyotishi or using a digital tool. The key data needed is name, date of birth, time of birth, and place of birth.
Step 2: Run Ashta Koota Guna Milan. The Nakshatras of both partners are compared across 8 kootas: Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakut, and Nadi. Each koota is scored, and the total is expressed as a Guna score out of 36.
Step 3: Check for Doshas. Nadi Dosha, Bhakut Dosha, and Gana Dosha are checked within the Guna Milan system. Additionally, Mangala Dosha is assessed from each jataka individually by checking Mars’s house placement.
Step 4: Review exceptions and cancellations. Any Doshas found are checked against the classical exception conditions. Nadi Dosha may be cancelled if both partners have different Rashis. Mangala Dosha is cancelled if both partners have it.
Step 5: Overall assessment. The final picture is evaluated — Guna score + Dosha status + exception outcomes — to determine whether the match is auspicious, acceptable with caution, or inadvisable.
Janmakshar Matching vs Guna Milan — What’s the Difference?
Janmakshar matching (or jataka matching) refers to the complete practice of comparing two horoscopes for marriage — including Guna Milan, Dosha analysis, Navamsha review, and Dasha compatibility. Guna Milan is specifically the Ashta Koota scoring component within the broader jataka matching process. In everyday usage, many families say “janmakshar matching” when they mean specifically the Guna Milan score — but technically, a full jataka matching includes more than just the Guna score.
Regional Variations in Jataka Matching
Karnataka (Jataka Porutham): Uses the standard 8-koota Ashta Koota system. Mangala Dosha is taken very seriously. The Navamsha (D9) chart is commonly reviewed. Community traditions vary between Brahmin, Lingayat, and Vokkaliga families.
Maharashtra (Janmakshar Milaan): Similar to the standard Ashta Koota system. Rajju Dosha is sometimes included. Marathi Brahmins often follow specific Dharmasindhu guidelines for muhurta and compatibility.
Andhra Pradesh & Telangana (Jathakam): Uses the Dashakoota (10-koota) system, which adds Rajju and Vedha checks to the standard 8 kootas. Rajju specifically checks for potential widowhood and is considered very important.
Tamil Nadu (Jathagam Porutham): The 10 Porutham system is used — with parameters: Dina, Ganam, Yoni, Rasi, Rasyadhipati, Vasya, Rajju, Vedha, Mahendra, and Stree Deergham. Rajju and Dina are typically considered most critical.
Gujarat (Janmakshar): Closely follows the standard Ashta Koota system. The Manglik assessment is particularly emphasised, and a Shanti puja is commonly recommended even for partial Mangala Dosha.
How to Do Jataka Matching Online for Free
Doing jataka matching online is straightforward with a reliable tool. You will need name, date of birth, time of birth, and place of birth for both partners.
The Sahita app performs jataka matching online for free on Android: enter birth details, the app calculates Nakshatra, Rashi, and Lagna for both, runs the full 8-koota Guna Milan analysis, flags Nadi Dosha and Mangala Dosha with exception checks, and generates a complete janmakshar compatibility report. The report can be shared via WhatsApp or downloaded as a premium PDF.
What to Check Beyond the Guna Score
A complete jataka matching for marriage goes beyond the Guna score. Experienced Jyotishis also examine the Navamsha chart (D9) — the divisional chart specifically for marriage — checking the 7th house, Venus placement, and 7th lord. The 7th house and lord in the main Lagna chart reveals the nature of the spouse and marriage prospects. Marriage timing (Dasha-Antardasha) analysis indicates when marriage is likely and whether the planetary periods running during the wedding year are favourable.
Summary
Janmakshar matching and jataka matching for marriage are regional terms for the same essential Vedic practice — comparing two birth horoscopes to assess marriage compatibility. The core method is the Ashta Koota Guna Milan system, producing a score out of 36. Regional variations exist (Karnataka, Maharashtra, Andhra, Tamil Nadu each have their specific traditions), but the underlying logic is consistent. The Sahita app makes jataka matching online simple, free, and comprehensive. Download on Android.
