StructureMetal Day Master × the Dragon (Earth)

Yang Metal — a forged sword. You are seated on the earth energy that feeds you — there is something to lean on underfoot.

Twelve-stageNurture

Raised in someone’s care. Optimistic and rounded, the temperament that softens the space between people.

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.

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

Steel forged on a dragon’s back — the grit to push at scale is the grain here. It does not bend under ordinary pressure, and it struggles precisely where bending is what wins.

Frequently asked

How do I know if I have the Geng Chen day pillar?

Your day pillar is the stem-branch pair governing the day you were born — Geng Chen (庚辰) 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 Geng Chen day pillar like?

White Dragon — the image traditionally attached to it is "Steel forged on the dragon’s back". Your Day Master 庚 (Yang Metal — a forged sword) sits on 辰, the Dragon, which carries Earth. In the twelve-stage cycle that position reads as Nurture, 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. 庚辰 is romanised Geng Chen from Mandarin and gyeongjin 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.
