Ding Wei (丁未) Day Pillar — Yin Fire on the Goat

The Ding Wei day pillar pairs the Ding day master (Yin Fire) with the Wei branch (Earth, the Goat). 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.

Computed facts (engine-verified)

How Ding sits on Wei

The stem generates the branch: Fire flows into Earth, so the Ding 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: Celestial River Water

Celestial River Water (天河水): the Milky Way — water at cosmic scale, above ordinary terrain. The image is aspiration beyond ground level.

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 Ding 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 己 (Ji, Eating God) defines the palace's classical group: Output. Middle/residual tenants: Ding (Peer), Yi (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 Ding Wei (丁未) day pillar?
The Ding Wei day pillar pairs the Ding stem (Yin Fire) with the Wei branch (Earth). Its computed facts: hidden stems Ji (Eating God), Ding (Peer), Yi (Indirect Resource), the Ding stem at the Attiring stage on this branch, seat relation "undefined", and nayin Celestial River Water (天河水).
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 Ding Wei day pillar good or bad?
Neither, on its own. The seat relation (undefined) and the Attiring 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 Celestial River Water mean?
Nayin (天河水) is a two-thousand-year-old classification that gives each PAIR of pillars a symbolic element-image — for Ding Wei it is "Celestial River Water", shared with its partner pillar Bing Wu (丙午). It is a classical gloss layer, published here alongside the structural facts, never instead of them.
