BaZi compatibility is more than zodiac matching
A useful compatibility check compares both charts, not just the birth year animal. Day Master relationship, spouse palace, element balance, and timing overlap all matter.

Many readers start by asking whether two signs match. This page returns that question to full two-person chart comparison.
Compatibility content should stay careful: it can describe tendencies and friction points, but it should not make deterministic claims about a relationship.
How to use this guide
Start with the chartRead the concept after calculating the chart so the page answers a real symbol in front of you.
Check adjacent conceptsDay Master, Five Elements, Ten Gods, and timing layers affect each other.
Avoid single-symbol readingOne branch, element, or Ten God is not enough to describe a full pattern.
Use careful languageTreat the page as a study reference, not a deterministic prediction.
Reading caution
BaZi content is most useful when it explains structure, tradeoffs, and timing context. It should not replace professional advice or pressure a personal decision.
