Ding Hai · 丁亥
Ding Hai pairs a Yin Fire 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 Fire · 丁 — The classical image for 丁 is a lamp or candle flame: heat gathered to a point, lighting a chosen circle. A Yin Fire Day Master tends to warm specifically — one person, one problem, one room at a time — and to notice what broad light washes out.

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
Authority
Authority with structure — rules, reputation, duty, and roles that hold you accountable.
甲
Direct Resource
Direct resource — care, credentials, protection, and knowledge that steadies the self.
Na Yin
The Na Yin of Ding Hai is 屋上土 — "Rooftop Earth". 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
Conception — Seeded — a new cycle is conceived but not yet visible.
Void branches (Xun Kong)
Charts anchored on 丁亥 treat 午未 as "void" — branches whose signals are read as weakened or delayed rather than absent.
Is Ding 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.
