Auspicious Renovation Start Dates for November 2027裝修 · November 2027

By Master Sean Chan · Updated

This month carries Li Dong (立冬) — start of the BaZi winter on November 7 (Singapore time): the BaZi calendar's sectional boundary for the month. Winter starts; Water-element days take precedence in many ranking shifts that follow.Below is the universal Chinese metaphysics ranking of every day in November 2027 for breaking ground on renovation (動土 / 修造), derived from the classical Tong Shu (通書). Renovation is an Earth-disturbing act and is more sensitive to Earth-related taboos than weddings or business openings.

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 is 土王用事 and why is groundbreaking restricted then?

土王用事 are the four 18-day windows around each seasonal transition when the Earth phase is dominant. Disturbing the ground during these windows is taboo for renovation, foundation work, and excavation. The page’s hard-requirement filter excludes these days; for a personal alignment we also check your Earth-element balance.

Methodology

Each day’s pillar is computed from the 60 Jiazi rotation anchored against the published Tong Shu, not from any single calendar app. The BaZi year flips at Li Chun (立春) and the BaZi month flips at every sectional solar term, both calculated from VSOP87 solar-longitude data so the boundaries land on the right minute. Twelve Officers and the 28 Mansions each rotate deterministically against well-known anchors.

The per-purpose weights are Dong Gong’s (董公擇日) — adjusted where modern almanacs disagree, in favour of the Hong Kong Observatory and Taiwan CWB lineage. Auspicious stars add to the score, taboo stars subtract, the day’s officer and mansion shift it further, and Yellow Dao adds a final small bonus. The final number gets capped at 100 and mapped to one of five tiers.
