How Geng sits on Shen

Stem and branch share one element: Metal over Metal, so the Geng day master is seated on its own kind — a genuine root. The traditional name is 比和 (bǐ hé, "same kind"). Of all sixty pillars this arrangement gives the day master the most unambiguous footing: the base and the self speak the same element, for better or worse, and the rest of the chart decides which.

Nayin: Pomegranate Wood

Pomegranate Wood (石榴木): pomegranate — wood valued for bearing many fruits. Output and abundance are the theme.

The spouse palace (day branch)

In the spouse palace this is a Peers (比劫) configuration: the classical reading treats the partner-side branch as the same element as the Geng day master — a companion seat. The structural point — stated by the tradition, not by this site — is that closeness here tends to resemble friendship and side-by-side effort. Whether that sustains an actual marriage depends on the whole chart, which is precisely why this page makes no prediction.

The main qi 庚 (Geng, Peer) defines the palace's classical group: Self & Peers. Middle/residual tenants: Ren (Eating God), Wu (Indirect Resource).

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 Geng Shen (庚申) day pillar?
The Geng Shen day pillar pairs the Geng stem (Yang Metal) with the Shen branch (Metal). Its computed facts: hidden stems Geng (Peer), Ren (Eating God), Wu (Indirect Resource), the Geng stem at the Official Post stage on this branch, seat relation "undefined", and nayin Pomegranate Wood (石榴木).
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 Geng Shen day pillar good or bad?
Neither, on its own. The seat relation (undefined) and the Official Post 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 Pomegranate Wood mean?
Nayin (石榴木) is a two-thousand-year-old classification that gives each PAIR of pillars a symbolic element-image — for Geng Shen it is "Pomegranate Wood", shared with its partner pillar Xin You (辛酉). It is a classical gloss layer, published here alongside the structural facts, never instead of them.
