How to Compare Two Jathagams for Marriage: A Complete 2026 Guide

Introduction

Are you about to take the most important decision of your life — and wondering if the stars align?

Before you say yes to a marriage proposal, Tamil families across the world ask one powerful question: how do you compare two Jathagams for marriage the right way?

This is not just a ritual. Jathagam comparison is a sophisticated astrological science that has guided South Indian families for thousands of years. It looks deep into the birth charts of both individuals — examining planetary positions, nakshatra compatibility, and life-path alignment.

In 2026, more people than ever are turning to professional astrologers and trusted platforms like Astromila.com to get this done accurately. Here is your complete, clear, step-by-step guide.

What Is a Jathagam and Why Does It Matter for Marriage?

A Jathagam is your personal astrological birth chart, cast based on your exact date, time, and place of birth. Unlike the North Indian term "Kundali," the Tamil term Jathagam carries its own unique depth and tradition rooted in South Indian Jyotish.

Your Jathagam maps all nine grahas — Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu — across 12 rasis. This snapshot of the sky at your birth moment tells your entire life story. When two Jathagams are placed side by side for marriage, astrologers look for harmony, balance, and long-term compatibility between two souls.

Getting this step right can mean the difference between a thriving partnership and a lifetime of struggle.

Understanding Dasa Porutham: The 10-Point Compatibility System

Here is where most people get confused — and it matters enormously.

Tamil marriage compatibility uses the Dasa Porutham system, also called Pathu Porutham, which evaluates 10 compatibility points. This is specific to South Indian astrology practiced in Tamil Nadu, Kerala, Karnataka, and Andhra Pradesh.

The 10 Poruthams are: Dina, Gana, Mahendra, Stree Deerga, Yoni, Rasi, Rasyadhipati, Vasya, Rajju, and Vedha.

Do not confuse this with the North Indian Ashta Koota system, which uses only 8 compatibility points. Tamil astrology never uses Ashta Koota for marriage matching. When someone tells you to check "Ashta Porutham" for a Tamil wedding — that is simply incorrect. Always insist on the proper Dasa Porutham evaluation from a qualified Josiyar.

Each of the 10 poruthams tests a specific dimension of married life, from physical health and children to emotional bonding and longevity of the relationship.

How to Compare Two Jathagams for Marriage Step by Step

Learning how to compare two Jathagams for marriage requires understanding a clear process. Follow these steps before approaching any astrologer.

Step 1: Gather Accurate Birth Details. Collect the exact date, time, and birthplace of both individuals. Even a 10-minute error in birth time can change nakshatra placements completely.

Step 2: Identify the Janma Rasi and Janma Nakshatra. The Moon's position determines both the Rasi (zodiac sign) and the Nakshatra (birth star) of each person. There are exactly 27 nakshatras in Tamil Jyotish. These two details form the foundation of Porutham calculation.

Step 3: Evaluate All 10 Poruthams. Have a skilled Josiyar calculate all 10 poruthams individually. The minimum acceptable score for a Tamil wedding match is traditionally considered to be at least 6 out of 10.

Step 4: Check Rajju and Vedha Carefully. Among all ten, Rajju and Vedha poruthams carry the most weight. A mismatch in Rajju is considered inauspicious for the longevity of the partner. These two must never be overlooked.

Step 5: Review Planetary Doshas. Beyond poruthams, check for Chevvai Dosham (Mars affliction), Sani-related challenges, and Rahu-Ketu axis placements in both charts.

The Role of Chevvai Dosham in Jathagam Matching

Chevvai Dosham — also called Mangal Dosha in other traditions — occurs when Mars occupies specific house positions in the Jathagam. In Tamil astrology, this is taken very seriously. When both partners carry Chevvai Dosham, the dosha is said to cancel out, making them compatible despite the affliction. A qualified Josiyar will identify this clearly.
