Green Tiger · The lead tree of the tiger’s forest
Yang Wood — a tall, upright tree. Your day branch carries the same wood energy as your Day Master — you are seated on your own root.
Earning its own keep. Self-reliance and practical competence sit firmly in this seat.
Your own energy is seated in your inner room. Backbone is solid and you stand well alone — and you meet the people closest to you as equals, which can mean bumping into them.
The stems concealed inside 寅 (Tiger). A branch is not one single energy — it holds this mixture, in these proportions across a 30-day month.
The lead tree of the tiger’s forest — upright, deep-rooted, unmistakably itself. Bending its own intent is difficult, so it shines at the front and chafes in the seat that supports someone else.
Is Jia Yin actually your day pillar?
The day pillar shifts on solar-term and zi-hour boundaries, so it is not countable by eye. Enter your birth date and the engine computes it in under a minute — free, no account.
Find my day pillar — freeYour day pillar is the stem-branch pair governing the day you were born — Jia Yin (甲寅) in this case. It rotates every day through a cycle of sixty, and the boundaries depend on solar terms and the 11pm zi-hour rule, so it is not something you can count by eye. Enter your birth date in our free reading and the engine computes it directly.
Green Tiger — the image traditionally attached to it is "The lead tree of the tiger’s forest". Your Day Master 甲 (Yang Wood — a tall, upright tree) sits on 寅, the Tiger, which carries Wood. In the twelve-stage cycle that position reads as Prime, and the seated Ten God is Companion.
No. The day pillar is two characters out of eight — your core axis, not the whole picture. The year, month and hour pillars, the balance of the five elements, and your decade luck all have to be laid on top before a reading means much. Treat a day-pillar page as the doorway, not the room.
Same sixty-cycle, different reading of the same characters. 甲寅 is romanised Jia Yin from Mandarin and gapin from Korean, and Korean saju calls the day pillar ilju (일주). The calculation is identical; the interpretive traditions differ.
The twelve-stage position, seated Ten God and hidden stems are computed by the Ioreum deterministic engine (ruleset ioreum-2026.07). The reading itself is interpretation from the day-pillar tradition, not verified science — we always tell you which part is calculation and which part is tradition.
