The Jia day master, computed

"What are Jia people like" is a high-frequency search whose answers are almost all borrowed adjectives. This page goes the other way: everything computable about Jia (Yang Wood) 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.

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 Jia day master like?
Classical texts attach adjectives to every day master, but adjectives cannot be audited. This page gives the computable structure: Jia is Yang Wood, Lu at Yin, blade at Mao, noblemen at Chou and Wei, 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 Jia own only six day pillars?
The sixty jiazi pair stems and branches of matching parity: Jia is a Yang stem, so it only sits on Yang 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.
