Saju Compatibility — when two charts meet

Compatibility (gunghap) overlays two charts to read day-pillar harmonies, element complement, and ten-god flows — far beyond zodiac matching.

Outer vs inner compatibility

Year-pillar match is "outer," day-pillar match is "inner." For deep partnerships, day-pillar weighs more.

Element complement

Pairings that fill each other’s element gaps stabilize over time; matched biases amplify shared weaknesses.

No "bad" compatibility

No combination is "doomed." Difficult charts simply need more conscious operating strategies.
