Tong Shu 通書 Daily Almanac: 2026-09-18 — 开 Day | iGeomancy

Opening

2026-09-18 (Lunar 8/8) is a definitive 开 (Opening) day in Tong Shu, marked by the auspicious Jianchu God. This is not merely a ‘good day’ but a celestial mandate for new beginnings: all initiatives involving launch, expansion, or renewal carry amplified success energy. For Singaporeans, this means optimal timing for HDB flat move-ins (avoiding void branches), CBD business debuts, wedding ceremonies, and launching new food stalls at hawker centres. Critically, avoid all activities related to endings—no funerals, estate settlements, or finalizing old contracts. The day’s Wood Goat (乙未) energy harmonizes with Fire Rooster (丁酉) month, creating fertile ground for growth. As the ancient text states: “开者，万物始生之象也，宜推新布旧，不宜守旧待终.” Today’s celestial alignment makes it a rare opportunity for transformative action across Singapore’s urban landscape.

Today’s Day Pillar 今日日柱

乙未 (Yin Wood Goat) is the day pillar for 2026-09-18, representing flexibility, growth, and harmony. The hidden stems (地支藏干) reveal 未支 contains 己 (Yin Earth, main), 丁 (Fire, mid), and 乙 (Wood, residual), creating a stable foundation with creative potential. This Wood energy thrives under Fire (Year 丙午) via 午未合火 (Harmonious Fire Combination), making today ideal for collaborative projects. The Yin Wood nature means gentle, persistent efforts—like planting orchids in a HDB balcony or drafting a new business plan—will yield results. However, avoid aggressive negotiations (Wood clashes with Earth in 未’s residual), as 乙未 day prefers natural flow over force. For Singaporeans, this translates to: open your new Kopitiam without shouting sales pitches; let the menu design unfold organically.

建除神 Jianchu Guide — 开 (重新开展的好日子。 宜：祭祀、祈福、开光、入宅、嫁娶、上任、修造、动土、开市、安床、交易、出行、竖柱。 忌：诉讼、安葬。)

Today’s 开 (Opening) designation is the celestial green light for all new beginnings. In Singapore contexts, this means:
✅ **DO**: Register for a new HDB flat renovation (avoid 丑时), launch a food delivery app (post-05:00), schedule a wedding at Ritz Carlton (before noon), or begin a new job at the CBD (11:00am+). The Wood Goat energy harmonizes with Fire Rooster month, making relationship-building effortless—ideal for networking at Clarke Quay after 21:00.
❌ **AVOID**: Funeral arrangements (Singapore’s cemeteries are closed for new burials on 开 days), finalizing old property deals (avoid 19:00-21:00), or any ‘ending’ activities (e.g., closing a stall at 11:00pm). The ancient text warns: “开日不宜埋葬，恐伤生气而损福寿.” For Singapore, this means no last-minute hawker stall sales on this day—save that for a 闭 (Closing) day later. The day’s energy is for growth, not extraction.

逐时宜忌 Hour-by-Hour Auspicious Windows 时辰指南

子时 (23:00–01:00) — ⚠ 伤官

Avoid all decisions; energy is disruptive (伤官). Best for winding down—no business calls. If networking, limit to 23:00-23:30 (天乙贵人 active). Never sign contracts this hour.

丑时 (01:00–03:00) — ⚠ 食神 [CLASH]

Clashing energy—avoid financial moves. Ideal for quiet reflection (e.g., reviewing your budget at 1:30am). Never schedule meetings; the clash weakens all plans.

寅时 (03:00–05:00) — ⭐ 正财

Prime for wealth activities: check bank balances, finalize supplier payments, or negotiate new contracts. Singapore’s financial district (CBD) is most auspicious at 3:00am—use this for quiet strategic planning.

卯时 (05:00–07:00) — ➜ 偏财

Good for casual income (e.g., selling handmade crafts at Tiong Bahru Market). Avoid major deals; the energy is scattered. Ideal for morning coffee chats with potential partners.

辰时 (07:00–09:00) — ➜ 正官 [VOID]

Void branch—avoid important meetings. Perfect for routine tasks (e.g., filing documents at 7:30am). Never sign contracts; the energy won’t materialize.

巳时 (09:00–11:00) — ➜ 七杀 [VOID]

Void branch; avoid travel or work decisions. The 驿马 (Travel Horse) activates at 9:00am—but skip travel plans. Ideal for coffee breaks before 10:00am.

午时 (11:00–13:00) — ⭐ 正印

Peak for education and strategy: attend workshops, draft proposals, or study for exams. The 文昌贵人 (Academic Star) enhances clarity—perfect for Singapore’s NUS or NTU students.

未时 (13:00–15:00) — ➜ 偏印

Good for creative work (e.g., designing menus for new restaurants). Avoid financial discussions; energy is indirect. Ideal for lunchtime brainstorming.

申时 (15:00–17:00) — ➜ 劫财

Caution: 劫煞 (Robbery Star) active. Avoid spending money; protect valuables. Ideal for internal team meetings (no external contracts).

酉时 (17:00–19:00) — ➜ 比肩

Collaborative energy—perfect for team lunches (e.g., at Joo Chiat food stalls). Avoid solo decisions; work in pairs.

戌时 (19:00–21:00) — ➜ 伤官

Disruptive energy—avoid arguments. Ideal for relaxing at home (e.g., watching dramas at 19:30). Never discuss business.

亥时 (21:00–23:00) — ⭐ 食神

Prime for enjoyment: dine at new restaurants (e.g., at Maxwell Food Centre), share creative ideas, or enjoy music. Avoid financial planning—energy flows naturally.

今日神煞 Shen Sha Star Spirits

Today’s active stars offer clear guidance for Singapore life. 天乙贵人 (Heavenly Noble Star) flows during 子时 (11pm-1am) and 申时 (3-5pm), making networking at night markets or post-work drinks highly auspicious. For professionals, a 3:00pm meeting with a senior executive (avoiding 劫煞) can secure a promotion. 文昌贵人 peaks at 午时 (11am-1pm)—ideal for exam prep or pitching to clients. The 驿马 (Travel Horse) activates at 9am for travel decisions (e.g., booking KL trips), but avoid traveling in 巳时 (9-11am). 劫煞 at 申时 demands caution: guard your wallet during MRT commutes (3-5pm) and avoid impulsive buys. Void branches 辰巳 (7-9am, 9-11am) mean no important calls during these windows—schedules will stall.

今日风水方位 Feng Shui Directions for Today

The Wood element (乙未 day) energizes East (90°) and Southeast (135°). For Singapore HDBs: position your home office or dining table facing Southeast to attract growth energy—ideal for new business ventures. Wear green or teal (emerald is best) to harmonize with Wood energy; avoid red or purple. Place a live bamboo plant in your Southeast corner (e.g., HDB living room) to amplify prosperity. For CBD professionals, position your desk facing East to enhance creativity during meetings. Singapore’s climate makes Southeast ideal for all-day energy—avoid North (Water energy clashes with Wood).
