Auspicious Wedding Dates for February 2027結婚 · February 2027

By Master Sean Chan · Updated

This month carries Li Chun (立春) — start of the BaZi year on February 4 (Singapore time): the BaZi calendar's sectional boundary for the month. Pre-Li-Chun days still belong to the previous BaZi year — factor that into anything date-binding (registration, ground-breaking).Below is the universal Chinese metaphysics ranking of every day in February 2027 for a wedding ceremony, derived from the classical Tong Shu (通書). It applies to no specific couple — it shows which days the calendar itself favours or warns against based on the Twelve Officers (建除十二神), Twenty-Eight Mansions (二十八宿), monthly and yearly Shen Sha (神煞), and the Yellow/Black Dao (黃黑道) cycle.

Frequently asked

Why isn’t my day on the list of top 5?

The top list is the universal ranking before any personal adjustment. Many couples find their best date isn’t in the top 5. Once you account for your day pillars, the right day often shifts. That’s exactly the gap the BaZi-Aligned Date Report fills.

What does 大凶 mean and can it ever be overridden?

大凶 means the day fails a hard classical requirement: 月破 (month break), 歲破 (year break), or 四離/四絕 (a quarter-day boundary). These cannot be overridden by personal alignment; they are excluded categorically. Choose another day.

Why don’t you show times here?

Hour selection is personal. The right hour depends on your day pillar and the chosen day’s element relationship to it. Publishing universal “auspicious hours” misleads readers into thinking a generic hour is safe; it isn’t. Hours are included in the personalised report.

Where do these scores come from?

The classical Tong Shu (通書) tradition: 建除十二神 (Twelve Officers), 二十八宿 (Twenty-Eight Mansions), 月德 / 天德 (monthly and yearly virtue stars), 黃黑道 (Yellow/Black Dao), and the Dong Gong (董公) per-purpose rules. We compute these directly from astronomical solar terms — no app shortcuts.

What if my partner’s zodiac clashes with all the top dates?

Both partners’ year branches need to be respected. The universal ranking can’t see your partner; the personalised report does. In practice, the right wedding date is rarely the universally top-ranked one once both charts are considered. That’s expected, not a problem.

Methodology

Pillars use the 60 Jiazi day cycle anchored to the published Tong Shu. The BaZi year flips at Li Chun, the BaZi month flips at each sectional solar term — both computed from VSOP87 ephemeris data. The Twelve Officers (建除) and the 28 Mansions each have their own deterministic rotation against an authoritative anchor.

Weights come from the Dong Gong (董公擇日) school. Auspicious 神煞 add, taboo 神煞 subtract, the officer and mansion adjust, Yellow Dao adds a small bonus on top. Sum, clamp to 0–100, classify. No app shortcuts.
