Korean couples check this before they marry. Enter two birth charts and see how the day branches meet — free, no signup.
The score tells you the shape of the meeting. It doesn't tell you what each person actually does to the other, where the friction lands, or when it changes. The full compatibility reading does.
Get my free reading first →궁합 (gunghap) is the Korean reading of two charts together. Traditionally it was done by a family elder before a marriage was agreed, and it is still done today — often quietly, before anyone announces anything.
The day branch of each chart, which is the position read as the self in a partnership, plus the relationship between the two day stems and their elements. Six-harmony and three-harmony pairings raise it; a direct clash lowers it.
No. A clash pairing is read as high-friction, not doomed — plenty of long marriages sit there. What it predicts is the kind of work the relationship asks for, not whether it lasts.
