StructureEarth Day Master × the Ox (Earth)

Yin Earth — soft garden soil. Your day branch carries the same earth energy as your Day Master — you are seated on your own root.

Twelve-stageRepose

Storing away in the vault. Good at gathering, keeping and saving — and inclined not to show what is inside.

Seated Ten GodCompanion

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

Fields under snow, entirely willing to wait for the right season. It looks unhurried, and it has already drawn next year’s planting in full — preparation is this pillar’s weapon.

Is Ji Chou 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.

Frequently asked

How do I know if I have the Ji Chou day pillar?

Your day pillar is the stem-branch pair governing the day you were born — Ji Chou (己丑) 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 Ji Chou day pillar like?

Yellow Ox — the image traditionally attached to it is "Fields waiting for spring beneath the snow". Your Day Master 己 (Yin Earth — soft garden soil) sits on 丑, the Ox, which carries Earth. In the twelve-stage cycle that position reads as Repose, and the seated Ten God is Companion.

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. 己丑 is romanised Ji Chou from Mandarin and gichuk 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.
