Compatibility Snapshot
Enter two birth moments. See Sun and Moon sign patterns plus BaZi Day Master interaction (生克 cycle) on one screen, free.
How compatibility actually works
Most "love calculator" apps tell you a percentage and call it a day. That's not how astrology — Western or Chinese — actually reads relationships.
Western synastry normally compares exact cross-chart aspects. This free snapshot is deliberately smaller: it shows Sun and Moon sign patterns, not a full aspect calculation or a compatibility verdict.
BaZi compatibility looks at the five-element interaction. Each person's day master has an element (wood, fire, earth, metal, water). Some pairings feed (生 sheng) — wood feeds fire, fire feeds earth. Some pairings clash (克 ke) — wood breaks earth, earth dams water. Both feeding and clashing relationships can thrive; they just feel different.
Why two lenses help
Western sign patterns describe one layer of expression. BaZi describes how the two Day Master elements may generate, control, or mirror one another. Neither system proves what a relationship is or what it will become.
The paid action reading computes cross-chart aspects, compares the BaZi Day Masters, and uses individual birth hexagrams only when both times are known. It reports uncertainty instead of filling missing birth-time data with confident claims.
