Xin Chou (辛丑) Day Pillar — Yin Metal on the Ox

The Xin Chou day pillar pairs the Xin day master (Yin Metal) with the Chou branch (Earth, the Ox). Below: the computed facts, what the seat relation and twelve-stage position mean structurally, the nayin gloss, the classical reading of the spouse palace, and an instant lookup for your own pillar.

How Xin sits on Chou

The branch generates the stem: Earth feeds Metal, so the Xin day master is seated on ground that keeps producing it. In traditional wording this is 得地 (dé dì, "gaining ground") — the self is resupplied by its own base. The practical consequence is structural, not predictive: whatever else the chart does, this day master starts from a position where its root is being actively replenished rather than taxed.

Nayin: Wall Earth

Wall Earth (壁上土): earth plastered into an interior wall — ground that makes a space livable.

The spouse palace (day branch)

In the spouse palace this is a Resource (印) configuration: the classical reading treats this branch as a seat that Xin's partner-side Chou supplies and protects. The structural point — stated by the tradition, not by this site — is that closeness here tends to feel sustaining rather than demanding. Whether that is true of any actual marriage depends on the whole chart, which is precisely why this page makes no prediction.

The main qi (Ji, Indirect Resource) defines the palace's classical group: Resource. Middle/residual tenants: Gui (Eating God), Xin (Peer).

A note on what this page deliberately does not do: the internet is full of "60 personality types" tables that assign a fixed character to each day pillar. This site rejects that framing. A day pillar is a structural position — who sits where, on what kind of ground, with which hidden tenants. The same pillar reads differently under a different month command, and no meaningful judgement exists without the other six characters. Where the tradition offers a reading, it is labelled as the tradition's; this site's own contribution is that every number and term on this page is computed, versioned, and checkable against the methodology page.

Frequently asked

What is the Xin Chou (辛丑) day pillar?
The Xin Chou day pillar pairs the Xin stem (Yin Metal) with the Chou branch (Earth). Its computed facts: hidden stems Ji (Indirect Resource), Gui (Eating God), Xin (Peer), the Xin stem at the Nourishment stage on this branch, seat relation "undefined", and nayin Wall Earth (壁上土).
How do I find my own day pillar?
Use the calculator on this page (birth date is enough — the day pillar does not need a birth time) or the full chart calculator. Your day pillar is the third pillar of the four; each of the sixty has its own page on this site with the same computed structure.
Is the Xin Chou day pillar good or bad?
Neither, on its own. The seat relation (undefined) and the Nourishment stage describe position and flow, not fortune. A meaningful reading needs the month command and the other six characters — any source that grades pillars as lucky or unlucky is simplifying past what the system itself claims.
What does the nayin Wall Earth mean?
Nayin (壁上土) is a two-thousand-year-old classification that gives each PAIR of pillars a symbolic element-image — for Xin Chou it is "Wall Earth", shared with its partner pillar Geng Zi (庚子). It is a classical gloss layer, published here alongside the structural facts, never instead of them.
