Gunghap

궁합 · 宮合

Compatibility between two charts — still routinely checked before Korean marriages.

Gunghap compares two full charts rather than two star signs. It looks at how the day masters relate, whether the elements each person lacks are supplied by the other, and where clashes and combinations fall between them.

A good gunghap reading is not a score. The useful part is structural: it names the specific friction the pair will keep having, which is more actionable than a percentage.
