If you've tried a Korean Saju reading, the glowing character at the top is your Day Master (일간, ilgan). It is the single most important part of your chart: the one element that means “me.” In Western terms, it plays a role a little like your sun sign — the core of your identity that the rest of the reading revolves around.
Where the Day Master comes from
Korean Saju is built from four “pillars” — your birth year, month, day and hour. Each pillar has a heavenly stem and an earthly branch. Your Day Master is the heavenly stem of your birth day. That's why the exact day you were born matters so much: it decides which of the five elements is your core self.
The ten Day Masters
There are five elements — Wood, Fire, Earth, Metal and Water — and each comes in a Yin or Yang form, giving ten Day Masters in total:
- Yang Wood — a tall tree: upright, principled, a natural leader. Yin Wood — a vine or flower: flexible, gentle, adaptable.
- Yang Fire — the sun: radiant, generous, impossible to ignore. Yin Fire — a candle: warm, focused, intimate.
- Yang Earth — a mountain: steady, reliable, protective. Yin Earth — a field: nurturing, resourceful, practical.
- Yang Metal — raw ore or a sword: bold, decisive, strong-willed. Yin Metal — a jewel: refined, precise, quietly powerful.
- Yang Water — the ocean or a river: expansive, driven, ever-moving. Yin Water — dew or rain: intuitive, gentle, deeply feeling.

Why your Day Master matters
Once you know your Day Master, the rest of your chart makes sense. The other five elements in your pillars either support your Day Master (giving you resources and confidence), drain it (through creativity and giving), or challenge it (through pressure and growth). This balance shapes your personality, love life, career and fortune.
