How is compatibility calculated?

Traditional Saju compatibility focuses on the relation between the two day pillars. This page computes the day-branch relations (six harmonies, trines, six clashes, generation, conflict) and how each person's Five-Elements balance complements the other, as a score. Everything is computed locally in your browser. Compatibility is a reference tool and promises nothing about a relationship's outcome.

Basis: day-pillar relation (8 pts) + Five-Elements complement (4 pts) + Day Master Ten-God pairing (3 pts)

Basis: KST (UTC+9) · year boundary at Ipchun · day pillar changes at midnight (23:00 night Ja) · approximation error ±15 min
