Dates

When should I do it?

Pick the thing — a wedding, an engagement, a move, a first day, a last day, a project, a business, a car, a trip — and get five dates, ranked. Every one is read out of the Chinese almanac: its 宜 and 忌 lists, its Day Officer, whether it falls on a 黄道 or 黑道 day, and whether it clashes your zodiac animal.

The five layers this reads

Date selection — 擇日 — is one of the oldest continuously practised parts of Chinese metaphysics, and it is still normal for a family to check the almanac before setting a wedding date. None of it is invented here; it is read.

宜 and 忌
Every day in the Chinese almanac carries a list of what it is suitable for and what to avoid. 嫁娶 is marriage, 開市 opening a business, 入宅 moving in. These are the actual terms, not paraphrases.
建除十二神
The Day Officers, on a twelve-day cycle. 成 (accomplish), 開 (open) and 定 (settle) are read as constructive; 破, 危 and 閉 are not. Quitting is the exception — that is what 除 and 破 days are for.
黃道 and 黑道
Each day is governed by one of twelve 天神, six on the yellow path and six on the black. It is the broadest auspicious flag the tradition carries.
二十八宿
The lunar mansion the Moon occupies, each read as 吉 or 凶.
沖 — the clash
Every day clashes one zodiac animal. If it clashes yours, the tradition treats it as out — not a lower score, out. That is the part of this reading that is about you.

What this will not do

It will not tell you a date is dangerous, and it will not tell you a marriage will fail because you picked the wrong Tuesday. Choose the date that works for the people involved — the venue, the notice period, the flights — and use this to choose between the dates that already work. That is how the tradition is used by the people who actually use it.
