Compatibility calculator, by date of birth
Not a quiz, not sun signs. Two birth dates become two full charts — BaZi Four Pillars, numerology, Destiny Matrix — and one computed harmony score. Computed, not guessed.

What are you two, structurally?
Each gets its own reading — a marriage and a boss are not the same question. Or just run the quick check below.
What the calculator checks
- Element chemistry — do your core elements feed, mirror, or shape each other (五行 generation & control)?
- Palace bonds & clashes — how the day branches interact (六合 bond, 三合 trine, 六冲 clash, 害 friction).
- Mutual roles — what each of you structurally represents in the other's chart (十神).
- Number alignment — life-path families and your pair number, plus the arcana the pairing itself carries.
Every check is deterministic — the same two dates always produce the same score. That's the point: computed, not guessed.
For reflection, not prediction. Kismana
