Tong Shu 通書 Daily Almanac: 2026-08-18 — 定 Day | iGeomancy

Opening

2026-08-18 (Lunar 2026/7/6) is a 定 (Stability) day under the month pillar 丙申. This is a paramount day for consolidation and security—ideal for finalizing agreements, reinforcing foundations, and nurturing existing relationships. Do NOT initiate new ventures, travel for business, or engage in disputes. The Wood Rat day 甲子 (Yang Wood) energizes stability through the month’s Fire Monkey pillar, creating a powerful synergy for building enduring structures. Avoid all litigation and distant travel; focus on strengthening what you already possess. For Singaporeans, this means prioritizing HDB renovation contracts, CBD merger terms, and wedding arrangements over new projects or relocation plans.

Today’s Day Pillar 今日日柱

甲子 (Wood Rat, Yang Wood) is the day pillar for 2026-08-18. As the master stem, 甲 (Yang Wood) represents foundational strength, growth, and resilience—mirroring the Earth’s roots. The hidden stem of 子 (Rat) contains 癸 Water, which nourishes Wood, creating a harmonious flow. This day’s energy is deeply rooted in security and discipline. The year pillar 丙午 (Fire Horse) and month pillar 丙申 (Fire Monkey) both express 食神 (Eating God) energy toward 甲 Wood, enhancing creativity and resourcefulness. However, the 子午冲 (Rat-Horse clash) introduces volatility, urging careful management of sudden changes. For Singaporeans, this means prioritizing established workflows over reactive decisions—e.g., finalizing HDB flat repairs during 巳时 (09:00–11:00) rather than starting a new cafe venture.

建除神 Jianchu Guide — 定 (月令三合的日子。 宜：祭祀、祈福、嫁娶、造屋、求嗣、纳财。 忌：诉讼、出行、交涉。)

定 (Stability) is a 定 (month’s trine) day, meaning it harmonizes with the month’s energy (申 Monkey) through trine relationships. This is a day for sealing what is already built—never for constructing from nothing. 宜 (Auspicious): Rituals (e.g., HDB block prayers for safety), blessings for family (求嗣), marriage ceremonies (嫁娶), structural repairs (造屋), and collecting income (纳财). 忌 (Inauspicious): Court cases (诉讼), long journeys (出行), and negotiations (交涉). The clash between 子 (Rat) and 午 (Horse) in the year pillar creates urgency, so avoid decisions requiring sudden shifts. For Singapore, this means: 1) Sign your HDB renovation contract today (not next week), 2) Host a family blessing at Tiong Bahru Market (求嗣), 3) Never argue with a landlord or file a new complaint. The day’s energy is like cement: it binds, doesn’t build anew. Do not launch a new business or switch offices today—wait for a 更 (New) day.

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

子时 (23:00–01:00) — 比肩 (Companion Star)

甲子 pillar during 子时 (Companion Star) offers subtle partnership energy. Best for: Quiet family discussions (e.g., HDB apartment succession planning) or reviewing old documents. Avoid: Financial talks or signing anything—this hour lacks authority. The void branch (戌) makes promises weak.

丑时 (01:00–03:00) — 劫财 (Rob Wealth)

乙丑 pillar (Rob Wealth) peaks at 丑时—energy is unstable. Best for: Personal chores (e.g., cleaning HDB kitchens) but avoid all money handling. Avoid: Spending, paying bills, or sharing financial plans—this hour risks losses. The Heavenly Noble Star (天乙贵人) activates here, so seek help from elders (e.g., a parent’s advice) for family matters.

寅时 (03:00–05:00) — 食神 (Eating God)

丙寅 pillar (Eating God) is the top hour for creative work. Best for: Pitching ideas to clients (CBD meetings), writing contracts, or cooking for family (Tiong Bahru hawker center). Avoid: Travel—Travel Horse (驿马) is active, but this is for local commutes only. The Academic Star (文昌贵人) aids presentations.

卯时 (05:00–07:00) — 伤官 (Hurting Officer)

丁卯 pillar (Hurting Officer) creates friction. Best for: Personal reflection or light tasks (e.g., sorting documents). Avoid: Work meetings with superiors—this hour risks clashing with bosses. The Yang Blade (羊刃) peaks here; never make bold decisions.

辰时 (07:00–09:00) — 偏财 (Indirect Wealth)

戊辰 pillar (Indirect Wealth) flows gently. Best for: Checking bank balances or small purchases (e.g., hawker centre lunch). Avoid: Major investments—this hour’s wealth is temporary. The void branch (戌) weakens transactions.

巳时 (09:00–11:00) — 正财 (Direct Wealth)

己巳 pillar (Direct Wealth) is the prime hour for contracts. Best for: Signing deals (e.g., HDB renovation), collecting payments, or finalizing salary negotiations. Avoid: Any debate—this hour is for closure. Robbery Star (劫煞) warns against impulsive spending (e.g., buying a car).

午时 (11:00–13:00) — 七杀 (Seven Killings) [CLASH]

庚午 pillar (Seven Killings) clashes with the year pillar. Best for: Focused work (e.g., MRT commute planning) but avoid all conflict. Avoid: Arguments with colleagues or clients—this hour escalates tensions. The clash (子午冲) makes travel dangerous.

未时 (13:00–15:00) — 正官 (Direct Officer)

辛未 pillar (Direct Officer) is ideal for authority interactions. Best for: Meeting government officers (e.g., HDB repair permits), presenting to bosses, or signing formal documents. Avoid: Personal requests—this hour demands professionalism. The Heavenly Noble Star (天乙贵人) activates here; seek help from influential contacts.

申时 (15:00–17:00) — 偏印 (Indirect Resource)

壬申 pillar (Indirect Resource) supports research. Best for: Studying, writing reports, or planning long-term projects. Avoid: Financial decisions—this hour is for preparation, not action.

酉时 (17:00–19:00) — 正印 (Direct Resource)

癸酉 pillar (Direct Resource) is perfect for creative collaboration. Best for: Social events (e.g., Tiong Bahru community gatherings), writing, or romance (Peach Blossom star active). Avoid: Work emails—this hour is for networking, not tasks.

戌时 (19:00–21:00) — 比肩 (Companion Star) [VOID]

甲戌 pillar (Companion Star) during void branch (戌) is unreliable. Best for: Family meals (e.g., hawker centre dinner) but avoid all commitments. Avoid: Signing agreements or making promises—this hour’s energy is weak.

亥时 (21:00–23:00) — 劫财 (Rob Wealth) [VOID]

乙亥 pillar (Rob Wealth) in void branch (亥) risks loss. Best for: Relaxation (e.g., watching TV) but avoid all money matters. Avoid: Paying bills or sharing plans—this hour invites theft or overspending.

今日神煞 Shen Sha Star Spirits

The Heavenly Noble Star (天乙贵人) activates at 丑 and 未 hours, making it ideal to seek help from respected figures (e.g., a senior colleague for a work issue) during those windows. The Academic Star (文昌贵人) peaks at 巳时, boosting exam performance and presentations—perfect for CBD professionals preparing for client pitches. The Travel Horse (驿马) at 寅 hour suits local commutes but not long trips. The Peach Blossom (桃花) at 酉 hour elevates social magnetism—use for networking at hawker centres or community events. Avoid the Robbery Star (劫煞) at 巳 hour: never gamble or make impulsive financial choices. Void branches (戌亥) weaken all commitments—never sign contracts during these times.

今日风水方位 Feng Shui Directions for Today

Today’s Wood element energizes East (90°) and Southeast (135°). For HDB flats: Position your desk facing East (e.g., in a bedroom overlooking Tiong Bahru) to enhance stability. Wear green or emerald (e.g., a jade bracelet) to harmonize with Wood energy. Place a small bamboo plant (emerald green) in Southeast corners to attract abundance. Avoid red or purple (Fire clashes with Wood). For MRT commuters: Enter trains facing East (e.g., exit at Tiong Bahru station). For hawker centre vendors: Face Southeast when setting up stalls to secure income (纳财). Never face West (Metal) today—Metal depletes Wood energy.

今日宜忌总览 Activity Guide — Do and Avoid

✓ AUSPICIOUS TODAY

• Signing contracts: 木 (Wood) day stabilizes agreements. Use 巳时 (09:00–11:00) for direct wealth (正财) and 未时 (13:00–15:00) for authority validation (正官). Ideal for HDB renovation deals or business partnerships.
• Finalising plans: The 定 (Stability) day seals decisions. Complete MRT project timelines by 15:00 (未时) to avoid delays.
• Repairs: Structural work (e.g., HDB leak fixes) aligns with Wood’s foundation energy. Schedule during 酉时 (17:00–19:00) for smooth execution.
• Marriage: 定 day is ideal for weddings. The Peach Blossom (桃花) at 酉 hour enhances romance—host ceremonies after 17:00.
• Nagging income: Collect payments during 巳时 (09:00–11:00) when 正财 (Direct Wealth) peaks—avoids delays.

✗ AVOID TODAY

• Lawsuits: 定 day is for consolidation, not conflict. Litigation (诉讼) triggers the 子午冲 (clash), escalating disputes. Never file a complaint today.
• Travel to distant places: The day lacks mobility (出行 is inauspicious). Long journeys (e.g., Sentosa or Jurong) risk delays due to the clash. Only commute locally (e.g., MRT to CBD).
• Starting new projects: 定 day does not create new foundations. Initiating a new cafe, business, or relocation would clash with the day’s stability energy. Wait for a 更 (New) day.

Frequently Asked Questions

Q: Is 2026-08-18 a good day for weddings in Singapore?

A:

Yes, absolutely. 定 (Stability) day is ideal for marriage (嫁娶). The Peach Blossom (桃花) star activates at 酉 hour (17:00–19:00), enhancing romance. Avoid 21:00–23:00 (亥时) as it’s a void hour. For Singapore couples, host ceremonies at Tiong Bahru Community Centre after 17:00 for strong foundation.

Q: What does 定 (月令三合的日子。 宜：祭祀、祈福、嫁娶、造屋、求嗣、纳财。 忌：诉讼、出行、交涉。) day mean in Tong Shu?

A:

定 means ‘stability’—a day for securing what exists, not building anew. 宜 (Auspicious): Rituals (祭祀), blessings (祈福), marriage (嫁娶), repairs (造屋), children (求嗣), and income (纳财). 忌 (Inauspicious): Lawsuits (诉讼), travel (出行), and negotiations (交涉). It’s like cementing a foundation—never starting a new building.

Q: What are the best hours on 2026-08-18 for business in Singapore?

A:

The top hours are 寅 (03:00–05:00, 食神 for creativity), 巳 (09:00–11:00, 正财 for contracts), 未 (13:00–15:00, 正官 for authority), and 酉 (17:00–19:00, 正印 for networking). For CBD professionals, sign deals at 09:00–11:00 or meet officials at 13:00–15:00. Avoid 11:00–13:00 (午时) due to clash energy.

Q: Which feng shui direction is auspicious today for HDB owners?

A:

East (90°) and Southeast (135°) are auspicious for Wood energy. Position your desk facing East in your HDB bedroom or living room. Wear green/emerald (e.g., a jade bracelet) and place a bamboo plant in Southeast corners. Avoid West (Metal) to prevent energy depletion.

Q: What should I avoid doing on a 定 day?

A:

Never start new projects (e.g., launching a business or moving apartments), travel for work (出行), or engage in disputes (诉讼). The day seals existing foundations, so avoid all ‘new’ actions. Never sign contracts during void hours (19:00–23:00) as energy is weak.
