天合地合 · 天克地冲 · DAY PILLAR PAIRINGS
Day Pillar Compatibility: the Classical Pairings
In BaZi compatibility, the strongest signal is how two day pillars interact: the Day Masters above (the two selves) and the branches below (the two spouse palaces). Two configurations matter most — the Heaven & Earth Union (stems combine, palaces harmonize: the classical marriage match) and the clash pairing (stems control, palaces collide: the intense match).
