StructureFire Day Master × the Rabbit (Wood)

Yin Fire — warm candlelight. You are seated on the wood energy that feeds you — there is something to lean on underfoot.

Twelve-stageAiling

Energy folding inward. Sensitivity and empathy deepen here — the mind runs busier than the body.

Seated Ten GodIndirect Resource

An unorthodox teacher sits in the inner room. Intuition and an original mind sit here — along with a head too busy for deep sleep.

Hidden stems Jia · Resource · 10d Yi · Indirect Resource · 20d

The stems concealed inside (Rabbit). A branch is not one single energy — it holds this mixture, in these proportions across a 30-day month.

A lamp on a spring night — it will not carry far, but it warms whatever is beside it. Delicate and affectionate, and easily flickered by wind, which here means other people’s words. This pillar needs somewhere to set its heart down.

Is Ding Mao actually your day pillar?

Frequently asked

How do I know if I have the Ding Mao day pillar?

Your day pillar is the stem-branch pair governing the day you were born — Ding Mao (丁卯) 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 Ding Mao day pillar like?

Red Rabbit — the image traditionally attached to it is "A lamp lighting a spring night". Your Day Master 丁 (Yin Fire — warm candlelight) sits on 卯, the Rabbit, which carries Wood. In the twelve-stage cycle that position reads as Ailing, and the seated Ten God is Indirect Resource.

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. 丁卯 is romanised Ding Mao from Mandarin and jeongmyo 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.
