The Geng Chen day pillar pairs the Geng day master (Yang Metal) with the Chen branch (Earth, the Dragon). 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.
This page is generated from the engine, not hand-written; structural facts reconcile against the methodology page.
| Day master | 庚 Geng · Yang Metal |
|---|---|
| Day branch | 辰 Chen (Dragon) · Earth |
| Hidden stems | 戊 Wu (Indirect Resource, main qi); 乙 Yi (Direct Wealth, middle qi); 癸 Gui (Hurting Officer, residual) |
| Stage of the stem here | Nourishment (12 of 12) |
| Nayin | White Wax Metal · 白蜡金 (shared with Xin Si 辛巳) |
| Seat relation | Branch generates stem (de di) — traditional term: 得地 |
The branch generates the stem: Earth feeds Metal, so the Geng day master is seated on ground that keeps producing it. In traditional wording this is 得地 (dé dì, "gaining ground") — the self is resupplied by its own base. The practical consequence is structural, not predictive: whatever else the chart does, this day master starts from a position where its root is being actively replenished rather than taxed.

White Wax Metal (白蜡金): metal in its softest, freshest state — newly formed, easily shaped, not yet hardened. Timing and environment decide what it becomes.
In the spouse palace this is a Resource (印) configuration: the classical reading treats this branch as a seat that Geng's partner-side Chen supplies and protects. The structural point — stated by the tradition, not by this site — is that closeness here tends to feel sustaining rather than demanding. Whether that is true of any actual marriage depends on the whole chart, which is precisely why this page makes no prediction.
The main qi 戊 (Wu, Indirect Resource) defines the palace's classical group: Resource. Middle/residual tenants: Yi (Direct Wealth), Gui (Hurting Officer).
Birth date alone is enough — the day pillar never needs a birth time. The calculation runs in your browser; nothing is sent anywhere.
