Free instant Chaldean compatibility check for couples. Drop in both names and dates of birth. We tell you where your rhythms harmonise, where they grate, and exactly what each partner needs to feel met.
Drop in both names and dates of birth. We'll show how your Chaldean numbers interact — friction, flow, and where harmony lives. Run as many partner checks as you like — no signup, no limit.
Every person operates on a Chaldean Moolank — the root number from their date of birth. That number governs their natural rhythm: how fast they think, how they process emotion, how much stimulation they need, how they handle change, conflict and intimacy.
When two Moolanks match via the Chaldean friendship matrix, the relationship feels easeful. Disagreements resolve themselves once spoken. Each partner instinctively reads the other's silence. Time apart doesn't feel threatening.
When two Moolanks differ, the same disagreement that takes ten minutes in an aligned pair takes three days. Not because either partner is wrong — because the rhythms genuinely don't sync. The compatibility check reveals exactly where the synchronisation lives and where each person has to be more conscious.
The day of birth is reduced to a single digit. Born on the 14th → 1+4 = 5 (Mercury). Born on the 6th → 6 (Venus). Born on the 28th → 2+8 = 10 → 1 (Sun).
Each Moolank has a list of friend numbers. Mutual friendship (each in the other's list) is the strongest match. One-way friendship still adds harmony but asks for active reciprocation. Numbers outside both friend lists create the most rhythm-friction.
| Moolank | Friend numbers |
|---|---|
| 1 (Sun) | 1, 2, 3, 4, 9 |
| 2 (Moon) | 1, 2, 4, 7, 8 |
| 3 (Jupiter) | 1, 3, 6, 9 |
| 4 (Rahu) | 1, 2, 4, 6, 8 |
| 5 (Mercury) | 1, 3, 5, 6, 9 |
| 6 (Venus) | 3, 4, 5, 6, 9 |
| 7 (Ketu) | 1, 2, 7 |
| 8 (Saturn) | 2, 4, 6, 8 |
| 9 (Mars) | 1, 3, 5, 6, 9 |
The full date of birth is summed and reduced to give the Bhagyank — the destiny number. When both Bhagyanks are also friendly, the long-arc compatibility is reinforced. This is why some couples feel an immediate spark (Moolank match) but only some sustain it through life transitions (Bhagyank match too).
Mutual friendship. Score around 80%. "Sun meets Mars — your numbers reinforce each other. The leader in you finds genuine ease with the warrior in them. Most disagreements resolve themselves once spoken aloud." Strong harmony, with Mars supplying drive and Sun supplying clarity.

Love compatibility numerology compares two people's Chaldean numbers — Moolank (root number from date of birth) and Bhagyank (destiny number from full date) — using the Chaldean friendship matrix. The match reveals rhythm compatibility, communication patterns, friction points and what each partner needs to feel emotionally met.
Strong pairings include 1 × 9 (Sun × Mars), 2 × 7 (Moon × Ketu), 3 × 6 (Jupiter × Venus), 5 × 9 (Mercury × Mars) and 6 × 6 (Venus × Venus). Mutual friendship pairs are most stable. Caution pairs include 4 × 8 doubles. Every pairing can work — the score reveals where each partner needs to be more conscious.
Yes. Each partner's name carries its own vibration that can either amplify or dampen the natural Moolank match. Two people whose names align well with their own Moolanks tend to bring their best to the relationship. Names that fight the personal Moolank create internal friction that surfaces in partnership — most commonly as low energy, irritability or self-doubt that the partner mistakes for "us" problems.
A low score does not mean don't marry. It means the relationship asks for explicit communication, conscious patience and honest naming of needs — assumptions are where most friction lives in lower-aligned pairings. The score is a map, not a verdict. Many of the strongest long-marriages in history were "low-score" pairings where both partners learned to read each other's silence.
No. Numerology cannot predict choices. It maps energetic terrain. Two people on a low-compatibility pairing who choose conscious honest communication will outperform two people on a high-compatibility pairing who coast on assumed harmony. The math is descriptive, not deterministic.
No — but they're complementary. Kundli matching uses planetary positions at birth (jyotish). Chaldean compatibility uses numerical vibration (Moolank, Bhagyank, name number). Many couples run both: Kundli for life-stage karmic compatibility, Chaldean for daily-rhythm compatibility.
