The Jia Zi day pillar pairs the Jia day master (Yang Wood) with the Zi branch (Water, the Rat). 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.

| Day master | 甲 Jia · Yang Wood |
|---|---|
| Day branch | 子 Zi (Rat) · Water |
| Hidden stems | 癸 Gui (Direct Resource, main qi) |
| Stage of the stem here | Bathing (2 of 12) |
| Nayin | Gold in the Sea · 海中金 (shared with Yi Chou 乙丑) |
| Seat relation | Branch generates stem (de di) — traditional term: 得地 |
The branch generates the stem: Water feeds Wood, so the Jia 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.

Gold in the Sea (海中金): metal submerged in ocean depths — strength that is real but hidden, and must be drawn up before it can be used. Classical commentary pairs it with patience under pressure: the value is there, the visibility is not.
In the spouse palace this is a Resource (印) configuration: the classical reading treats this branch as a seat that Jia's partner-side Zi 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 癸 (Gui, Direct Resource) defines the palace's classical group: Resource.
Birth date alone is enough — the day pillar never needs a birth time. The calculation runs in your browser; nothing is sent anywhere.
