Day Master (BaZi)

In BaZi Four Pillars, the Day Master (日主) is the Heavenly Stem of your Day Pillar. It represents your core self: how you act, react, and express. There are 10 Day Masters — five elements (Wood, Fire, Earth, Metal, Water) × two polarities (Yin, Yang). Yang Wood is the tall tree: growth-oriented, principled, stubborn. Yin Fire is the candle: warm, intimate, charming. Your Day Master shapes your personality, compatible professions, and relationship dynamics.
