Your Ilju (Day Pillar) IS You
In Saju, the most important pillar is the Ilju (日柱) — the Heavenly Stem and Earthly Branch combination of your birth day. It plays a role similar to your "Sun sign" in Western astrology, but with 60 possible types instead of 12, Saju offers far more precise personality analysis.
You might expect 10 Stems × 12 Branches = 120 combinations, but there are only 60 because Yang Stems pair only with Yang Branches, and Yin Stems pair only with Yin Branches. This is the Yukshipgapja (Sexagenary Cycle) we covered in G2.
How to read each card:
Each Ilju consists of "Heavenly Stem + Earthly Branch." The Stem represents your core personality (Day Master), while the Branch represents your environment, relationships, and inner world. The unique character born from this combination is the essence of Ilju theory.

Ilju theory is just the beginning:
Your Ilju is the starting point of Saju analysis, not the whole picture. Even two people with the same Gap-ja day pillar can have very different personalities depending on their Year, Month, and Hour pillars. Think of your Ilju as your "operating system" — the other pillars are the "apps installed on it."
