Methodology
How this tool works
The checker calculates two approximate charts, compares zodiac branch combinations and clashes, counts visible Five Elements from stems and branches, and turns the comparison into plain-language notes.
Cultural variation notes
- Marriage matching traditions vary widely by dialect group, family, and practitioner.
- Some families prioritize couple charts; others also consider parents, wedding date, and household altar practice.
- Compatibility should never be used to pressure, exclude, shame, or override consent.
FAQ
Frequently asked questions
Does a clash mean a relationship will fail?
No. Clash language is symbolic and contextual. Families who use it often look for mitigation, timing, and harmony practices rather than treating it as fate.
Can I compare without exact birth times?
Yes, but the hour pillar and element count become less reliable. Use the result as a partial comparison only.
Is this suitable for marriage decisions?
It can support cultural discussion, but it is not a substitute for consent, communication, legal requirements, health, finance, or professional advice.
