In Sri Lanka, almost every wedding begins with a question: කේන්දර ගැළපෙනවාද? — "Do the horoscopes match?" That question is answered through Porondam (පොරොන්දම්), the ancient Jyotish practice of comparing two birth charts to assess compatibility before marriage.
This guide explains what Porondam checks, why each factor matters, and how modern AI-powered analysis makes it deeper and more accurate than traditional score-based methods.
Porondam is the Sri Lankan term for the Vedic astrology practice of horoscope compatibility matching (known in India as Kundli Milan or Jyotish Synastry). It compares the birth charts of two people — typically a prospective bride and groom — to assess whether their union will be harmonious, prosperous, and long-lasting.
The practice has been central to Sri Lankan Buddhist and Hindu wedding traditions for centuries. Unlike Western sun-sign compatibility ("Are you a Leo? I'm a Sagittarius!"), Porondam is based on the precise positions of the Moon, the Ascendant (Lagna), and all nine planets at the exact moment of each person's birth.
Traditional Porondam and modern Jyotish synastry examine six core areas:
The compatibility of both people's Moon Nakshatras (lunar mansions). This includes Gana match — whether both are Deva (divine), Manushya (human), or Rakshasa (fiery) temperament — and Nadi dosha, which can indicate health challenges in offspring.
The relationship between the two Moon signs (Rasi). Certain Rasi combinations create natural emotional harmony; others create friction that needs to be consciously managed.
Whether Mars occupies the 1st, 4th, 7th, 8th, or 12th house in either chart. Mangal Dosha can indicate intensity and conflict in marriage. Crucially, Dosha in both charts often cancels — this is called mutual cancellation.
The 7th house governs marriage and long-term partnership in Vedic astrology. The sign, planets in it, and the lord of the 7th house tell the astrologer what kind of marriage each person is destined for.
The Atmakaraka (soul planet — the planet with the highest degree) and Darakaraka (the significator of the spouse — the planet with the lowest degree) are compared across both charts. This reveals deep soul-level compatibility.
The Vimshottari Dasha period both people are currently running. Getting married during a Venus or Jupiter Dasha is considered auspicious; Saturn or Rahu Dasha periods call for more care.
Traditional Porondam often produces a score out of 36. While a score below 18 is generally considered inauspicious, scores above 18 vary enormously in meaning. A couple can score 28/36 but still have a severe Mangal Dosha — or a deep 7th house conflict — that the score masks.
This is why the best astrologers don't just report a number. They read the narrative of both charts together: where the strengths lie, where the friction will appear, and what both people need to know before committing.
AI-powered analysis like Zodovia's goes further — it produces a full written reading that explains what the compatibility indicators mean for this specific couple, in plain language.
Traditionally, yes. But the same Jyotish synastry principles apply to any important relationship — a business partnership, a parent-child dynamic, a close friendship. Understanding the planetary interaction between two people's charts is valuable in any context where you need to understand why you connect deeply with some people and clash with others.

Check Your Porondam ✨An approximate time is sufficient for Nakshatra and Rasi compatibility. If the exact time is unknown, entering a session (morning / afternoon / evening / night) gives Zodovia enough information to calculate. For 7th house and Lagna-based analysis, an exact time improves accuracy significantly.
When both people have Mangal Dosha, they cancel each other — this is considered a positive match, not a negative one. The intensity of both Mars placements is balanced by the other person's equivalent energy.
Porondam is a tool for self-awareness, not a deterministic verdict. Even charts that show friction can lead to deeply fulfilling marriages when both people understand the dynamics at play. The value of a good Porondam reading is that it tells you what to work on — not whether to proceed.
