Xin Hai (辛亥) Day Pillar — Yin Metal on the Pig

The Xin Hai day pillar pairs the Xin day master (Yin Metal) with the Hai branch (Water, the Pig). 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 Hai

The stem generates the branch: Metal flows into Water, so the Xin day master sits on ground that continuously draws its output. Traditional wording calls this 泄 (xiè, "draining") — the self is spent into its own base. Again this is a statement of flow, not of fortune: the day master's energy has a standing outbound channel right under it, and the rest of the chart decides whether that channel is a liability or a productive one.

Nayin: Hairpin Metal

Hairpin Metal (钗钏金): metal worked into ornaments — refined metal at its most intimate and personal scale.

The spouse palace (day branch)

In the spouse palace this is an Output (食伤) configuration: the classical reading treats the partner-side branch as the place where the Xin day master expresses rather than absorbs. The structural point — stated by the tradition, not by this site — is that intimacy here runs through expression and making. Whether that lands well in an actual relationship depends on the other seven characters, which is why this page stops at structure.

The main qi 壬 (Ren, Hurting Officer) defines the palace's classical group: Output. Middle/residual tenants: Jia (Direct Wealth).

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 Hai (辛亥) day pillar?
The Xin Hai day pillar pairs the Xin stem (Yin Metal) with the Hai branch (Water). Its computed facts: hidden stems Ren (Hurting Officer), Jia (Direct Wealth), the Xin stem at the Bathing stage on this branch, seat relation "undefined", and nayin Hairpin Metal (钗钏金).
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 Hai day pillar good or bad?
Neither, on its own. The seat relation (undefined) and the Bathing 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 Hairpin Metal mean?
Nayin (钗钏金) is a two-thousand-year-old classification that gives each PAIR of pillars a symbolic element-image — for Xin Hai it is "Hairpin Metal", shared with its partner pillar Geng Xu (庚戌). It is a classical gloss layer, published here alongside the structural facts, never instead of them.
