The Geng Xu day pillar pairs the Geng day master (Yang Metal) with the Xu branch (Earth, the Dog). 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 | 戌 Xu (Dog) · Earth |
| Hidden stems | 戊 Wu (Indirect Resource, main qi); 辛 Xin (Rival, middle qi); 丁 Ding (Direct Officer, residual) |
| Stage of the stem here | Decline (6 of 12) |
| Nayin | Hairpin Metal · 钗钏金 (shared with Xin Hai 辛亥) |
| 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.

Hairpin Metal (钗钏金): metal worked into ornaments — refined metal at its most intimate and personal scale.
In the spouse palace this is a Resource (印) configuration: the classical reading treats this branch as a seat that Geng's partner-side Xu 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: Xin (Rival), Ding (Direct Officer).
Birth date alone is enough — the day pillar never needs a birth time. The calculation runs in your browser; nothing is sent anywhere.
