Yi Chou 乙丑
Green Ox · A wildflower that roots even in frozen ground
Yin Wood — a flowering vine. You are seated on the earth energy you control — a sense of the practical world lies underfoot.
Just past the summit. Seasoned and steady, better at holding what exists than at forcing expansion.
Money in motion is seated in your inner room. Resourcefulness, scale and activity are strong here — and so is the width of what comes and goes.
The stems concealed inside 丑 (Ox). A branch is not one single energy — it holds this mixture, in these proportions across a 30-day month.
Nothing showy, but the stubbornness to push through frozen ground is the underdrawing here. The staying power is real — and so is the habit of swallowing the hard parts instead of saying them out loud.

How do I know if I have the Yi Chou day pillar?
Your day pillar is the stem-branch pair governing the day you were born — Yi Chou (乙丑) 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.
What is the Yi Chou day pillar like?
Green Ox — the image traditionally attached to it is "A wildflower that roots even in frozen ground". Your Day Master 乙 (Yin Wood — a flowering vine) sits on 丑, the Ox, which carries Earth. In the twelve-stage cycle that position reads as Waning, and the seated Ten God is Indirect Wealth.
Does my day pillar tell me my whole chart?
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.
Why is it called Jia Zi in Chinese and something else in Korean?
Same sixty-cycle, different reading of the same characters. 乙丑 is romanised Yi Chou from Mandarin and eulchuk 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.
