Gui Hai · 癸亥
Gui Hai pairs a Yin Water Day Master with 亥 (the Pig), a Water branch. If this is your day pillar, the pairing below describes tendencies worth observing — not a verdict.
The Day Master on top
Yin Water · 癸 — The classical image for 癸 is rain, dew, still water: the water that reaches roots without announcing itself. A Yin Water Day Master tends to perceive first and speak later — patterns, moods, and implications register before anyone has named them.

In a day pillar, the branch is read as the spouse palace: the texture of close partnership. 亥 (the Pig) carries these hidden stems, each read as a relationship between that stem and your Day Master:
壬
Rival Wealth
Opposite polarity, same element — close competition, shared resources, sharp give-and-take.
甲
Output (Sharp)
Sharp output — wit, critique, and originality that can cut as well as create.
Na Yin
The Na Yin of Gui Hai is 大海水 — "Ocean Water". Na Yin is a poetic sixty-fold naming of the pillars, used as a secondary texture rather than a primary verdict.
Stage of the cycle
Peak — Peak force — maximum expression of the Day Master in this branch.
Void branches (Xun Kong)
Charts anchored on 癸亥 treat 子丑 as "void" — branches whose signals are read as weakened or delayed rather than absent.
Is Gui Hai actually your day pillar?
The day pillar comes from your exact birth date — and near midnight, from true solar time. Calculate it instead of guessing.
As with everything on Truenoon, this page describes observable tendencies, not a verdict on who you are.
