What's Included
A comprehensive compatibility analysis blending Western and Vedic techniques
Sun Sign Compatibility
Core identity match. How your ego, drive, and life direction align with theirs. The foundation of every compatibility reading.
Moon Sign Emotional Fit
How you each process feelings, seek comfort, and handle stress. Moon compatibility matters more for long-term relationships than Sun.
Venus Love Style
What you need to feel loved versus what they need. Venus in Taurus craves stability. Venus in Aquarius needs space. Mismatch here causes the most silent resentment.
Mars Passion & Drive
Physical chemistry, how you fight, and what motivates you. Mars in Scorpio and Mars in Aries have explosive attraction. Mars in Cancer and Mars in Capricorn grind in different gears.
Mercury Communication
How you argue, joke, plan, and process information. Mercury in Gemini talks fast and changes topics. Mercury in Taurus needs time to think before responding.
Jupiter Growth Alignment
Shared vision for the future. Where you both want to expand, travel, learn, and grow. Jupiter contacts between charts signal where you help each other level up.
Saturn Commitment Factor
The glue or the weight. Saturn aspects between charts show where you stabilize each other and where you restrict. Harmonious ones feel like building something real.
Element Balance
Fire, Earth, Air, Water distribution across both charts. Two people heavy in Fire but empty in Earth create excitement with zero follow-through. Balance is everything.
Vedic Ashtakoot Milan
The traditional 8-factor system used in Indian marriages for centuries. Compares Moon nakshatras across Varna, Vasya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, and Nadi. 36 points possible.
Understanding Compatibility Analysis
A compatibility checker compares the birth charts of two people to reveal how their planetary placements interact. Unlike a simple sun sign comparison, this tool examines dozens of connections — planet-to-planet aspects, house overlays, and sign harmonics — to build a complete picture of relationship dynamics.
Beyond Sun Signs
Most compatibility tools stop at Sun signs. That is like judging a book by three words on the cover. Your Sun sign is your conscious identity, the part of you that shows up in job interviews and first dates. But relationships live in the spaces between people, and those spaces are shaped by every planet in both charts. Moon signs reveal emotional needs. Venus shows love languages. Mars indicates attraction patterns. Mercury determines how you communicate under stress. A full compatibility analysis examines all of these — and the angles they form with each other across two charts.
Western Synastry: The Aspect Method
Synastry lays one person's chart on top of the other and checks where planets interact. If your Venus sits on their Mars, the attraction is almost chemical. If your Saturn squares their Moon, one of you feels emotionally suffocated while the other feels ignored. These are not metaphors. People describe these dynamics in therapy without knowing the astrology behind them. The key aspects — conjunction, trine, square, opposition, and sextile — each have a distinct flavor. Conjunctions fuse. Trines flow. Squares challenge. Oppositions magnetize. Sextiles open doors.
Vedic Ashtakoot: The Nakshatra Method
Vedic compatibility uses a completely different lens. Instead of planet-to-planet aspects, Ashtakoot Milan compares the Moon's nakshatra (lunar mansion) for each person across eight categories. This system has been used in Indian families for marriage matching for over two thousand years. Each of the eight kootas — Varna, Vasya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, and Nadi — measures a different dimension of compatibility, from spiritual alignment to physical chemistry. The total score runs from 0 to 36, with 18 or higher generally considered favorable.
Why We Run Both
Western and Vedic astrology use different zodiacs (tropical versus sidereal), different reference points (Sun versus Moon), and different logic. They sometimes agree completely and sometimes contradict each other. Both cases are useful. When both systems say the same thing, you can trust it more. When they disagree, you have a richer picture of where the relationship has easy flow and where it requires conscious effort.
The Mercury Factor Nobody Talks About
Communication compatibility is the single best predictor of whether a relationship survives its first real conflict. Mercury sign matching shows how two people process information, make decisions, and resolve disagreements. Mercury in a fire sign (Aries, Leo, Sagittarius) speaks before thinking and expects the same directness back. Mercury in a water sign (Cancer, Scorpio, Pisces) reads tone, body language, and subtext before responding, and can feel attacked by blunt delivery even when no attack was intended.
Venus-Mars Dynamics
Venus and Mars between two charts create the attraction-passion axis. Where Venus shows what you find beautiful and how you want to be romanced, Mars shows how you pursue and what ignites you. The classic "spark" people describe on first dates is usually a Venus-Mars contact between the charts. Venus conjunct Mars creates instant magnetic pull. Venus trine Mars offers easy, natural attraction. Venus square Mars generates intense chemistry with periodic friction. Understanding these dynamics helps couples navigate both the honeymoon phase and the years that follow.
Dosha: When the Chart Says Caution
Vedic astrology identifies specific chart conditions called doshas that signal potential obstacles in partnership. Mangal Dosha (Mars in the 1st, 4th, 7th, 8th, or 12th house) is the most commonly discussed, but Nadi Dosha and Bhakoot Dosha matter just as much. The important thing to know is that every dosha has specific cancellation conditions. Mangal Dosha cancels if both partners have it, or if Mars is in certain signs like Aries or Scorpio where it is dignified. Blanket fear about dosha is outdated. The details are what matter.

The 8 Kootas of Ashtakoot Milan
| Koota | Points | What It Measures | Why It Matters |
|---|---|---|---|
| Varna | 1 | Spiritual compatibility and ego dynamics | Determines who leads and who supports in the relationship’s spiritual dimension. |
| Vasya | 2 | Mutual attraction and magnetic control | Shows the power dynamic. Who has more influence over whom, and whether that influence is healthy. |
| Tara | 3 | Destiny and health compatibility | Based on birth star count from one nakshatra to the other. Certain counts are auspicious, others are not. |
| Yoni | 4 | Physical and sexual compatibility | Each nakshatra maps to one of 14 animals. Matching animals score highest. Enemy animals score zero. |
| Graha Maitri | 5 | Mental compatibility and friendship | Compares the Moon sign lords. Friendly lords = natural rapport. Enemy lords = friction in daily life. |
| Gana | 6 | Temperament match | Three ganas: Deva (gentle), Manushya (moderate), Rakshasa (assertive). Same gana scores full. Deva-Rakshasa scores zero. |
| Bhakoot | 7 | Emotional and financial harmony | Moon sign distance matters. 6-8 and 2-12 gaps carry Bhakoot dosha. Cancellation conditions exist. |
| Nadi | 8 | Health and genetic compatibility | Highest point value for a reason. Same nadi scores zero (Nadi dosha). Linked to progeny health. |
