Auspicious dates for Signing contracts — September 2027

Every day of September 2027 was evaluated for Signing contracts against the classical almanac rule tables — the 宜/忌 term lists, the twelve day officers (建除十二神) and the ecliptic stars (黄黑道). The days below cleared the bar and are ranked by net score; the 冲 column names the zodiac animal each day opposes. The computation is deterministic and identical to the daily almanac pages.

How dates are graded

The event is mapped onto the almanac vocabulary: a wedding matches 嫁娶 recommends, a move matches 移徙/入宅, an opening matches 开市. A day scores +3 when a core term sits in its 宜 list, −4 when it sits in 忌; favorable day officers (e.g. 成, 开) and Yellow Path stars add, their opposites subtract. Grades: best ≥ 5, good ≥ 3, fair ≥ 1 net score; everything below is left off the list.

Every day branch opposes (冲) the zodiac animal six steps away in the cycle. Give your birth year and the days that clash your own animal are flagged — traditionally a caution worth weighing even on an otherwise strong day.

Signing contracts: 宜 signing contracts / trading / sealing the engagement · receiving payments / gathering with relatives and friends / meeting friends · Day officer: Settle

Interpret these auspicious dates in two layers: 1) Structural Evidence: how the 宜/忌 term match, the twelve day officers (建除十二神) and the ecliptic stars (黄黑道) combine into each day's rank; flag each day's 冲 (clash) animal for readers born in that year. 2) Actionable Verdict: a practical shortlist of 2–3 dates for the event, with scheduling advice (lead time, fallback day) in plain language.
