What is Day Pillar (Ilju)?
The Day Pillar is considered the "master" of the Saju chart. Its Heavenly Stem (Day Master) represents your fundamental self—your approach to life, decision-making style, and core identity. The Earthly Branch of the Day Pillar indicates your spouse's characteristics and your domestic life. There are 60 possible Day Pillar combinations, each with distinct personality traits and destiny patterns. The Day Master's element and its relationship with other chart elements is central to Saju interpretation.
