The Xin day master, computed

"What are Xin people like" is a high-frequency search whose answers are almost all borrowed adjectives. This page goes the other way: everything computable about Xin (Yin Metal) is computed here — where Lu, the blade, the noblemen and Wenchang land, which stem it combines with and into what, which stem clashes it, its six of the sixty day pillars, and the twelve-stage strength of every branch. Every number is checkable and every rule is on the methodology page. No adjectives produced; structure you can audit.

Computed facts (engine-verified)

This page is generated from engine vv0.14.0; the Lu-equals-Official-Post and blade-equals-Prosperity cross-checks are asserted for all ten stems at build time — conventions R32/R34.

Day master Xin · Yin Metal
Lu — the Official-Post seat You — cross-checked: the Official-Post seat of Xin lands exactly here
Yin blade — the Prosperity seat Shen — the yin blade is one school's reading; another school gives yin stems no blade at all — divergence kept public
Nobleman branches (both schools)Wu and Yin (main) · Yin and Wu (alt) — the two schools disagree exactly on Geng and Xin
Wenchang — the study star Zi
Stem combine (and what it becomes)Xin combines with Bing; the pair transforms to Water
Stem clashYi — one of the four heavenly clashes
Twelve-stage startBirth begins at Zi, counting backward (Yin stems)
Day pillars carrying this stem6 of 60: 辛未 Xin Wei, 辛巳 Xin Si, 辛卯 Xin Mao, 辛丑 Xin Chou, 辛亥 Xin Hai, 辛酉 Xin You
Prosperity inside its own pillarsnone of the sixty day pillars puts Xin on its Prosperity branch (parity of stems and branches blocks it — see the index distribution)

The full twelve-branch scan (main qi × ten god × twelve stages × marks)

One row per branch: main-qi hidden stem, ten god against the day master, its twelve-stage strength, and where Lu, the blade, the noblemen and Wenchang land. Blanks in the marks column are information too.

Scan your own four pillars

Enter your birth moment (time optional). The page marks each of your four branches; if your day master is not this page's stem, it links to your own day-master page.

A note on what this page deliberately does not do: the popular versions of this material assign a fixed personality to each term — one character per branch, one destiny per stage. This site rejects that framing. What is published here is a structural position: which element sits where, on what kind of ground, with which tenants inside. The same term reads differently under a different month command, and no meaningful judgement exists without the other characters of the chart. 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 a Xin day master like?
Classical texts attach adjectives to every day master, but adjectives cannot be audited. This page gives the computable structure: Xin is Yin Metal, Lu at You, yin blade at Shen, noblemen at Wu and Yin, six of the sixty day pillars. Take the personality words or leave them — this site only produces the part you can check line by line.
How do I find my own day master?
The stem of your day pillar is your day master. Use the calculator on the home page. Note that the year pillar changes at Lichun (solar longitude 315 degrees) — not on New Year and not on the lunar first.
Why does Xin own only six day pillars?
The sixty jiazi pair stems and branches of matching parity: Xin is a Yin stem, so it only sits on Yin branches — exactly six of the twelve. That same parity decides the Prosperity row: if the Prosperity branch has the wrong parity, it never appears in a day pillar.
What do the marks (Lu, blade, nobleman) mean?
They are single-character-anchored structural positions. The scanner below marks which of your four branches carry them. Counts and landings are checkable; verdicts are not offered — whole-chart strength is the favorable-element calculator's job.
