The Gui Hai day pillar pairs the Gui day master (Yin Water) with the Hai branch (Water, the Pig). 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 | 癸 Gui · Yin Water |
|---|---|
| Day branch | 亥 Hai (Pig) · Water |
| Hidden stems | 壬 Ren (Rival, main qi); 甲 Jia (Hurting Officer, middle qi) |
| Stage of the stem here | Prosperity (5 of 12) |
| Nayin | Great Sea Water · 大海水 (shared with Ren Xu 壬戌) |
| Seat relation | Same element (bi he) — traditional term: 比和 |
Stem and branch share one element: Water over Water, so the Gui day master is seated on its own kind — a genuine root. The traditional name is 比和 (bǐ hé, "same kind"). Of all sixty pillars this arrangement gives the day master the most unambiguous footing: the base and the self speak the same element, for better or worse, and the rest of the chart decides which.

Great Sea Water (大海水): ocean water — the largest of the sixty, beyond banks and measurement. The classical reading is capacity that ordinary containers cannot hold.
In the spouse palace this is a Peers (比劫) configuration: the classical reading treats the partner-side branch as the same element as the Gui day master — a companion seat. The structural point — stated by the tradition, not by this site — is that closeness here tends to resemble friendship and side-by-side effort. Whether that sustains an actual marriage depends on the whole chart, which is precisely why this page makes no prediction.
The main qi 壬 (Ren, Rival) defines the palace's classical group: Self & Peers. Middle/residual tenants: Jia (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.
