  • Invite prosperity: choose a date that actively supports your goals and relationships.
  • Avoid misfortune: protect your critical milestones from clashes and negative energy.
  • Read the almanac: the Tong Shu, the 12 Day Officers, and the day each of them labels.

The Technique

A day is chosen for the person it begins.

Date selection (择日) works in layers. The almanac (黄历) grades the day itself; the twelve officers (建除十二神) give it its verdict; the individual's own BaZi says whether that verdict applies to the person beginning the matter. The course teaches the layers in that order, and then teaches what to do when they disagree.

  • The almanac read properly: the structure of a day's page, and the difference between 黄历 and 通书.
  • The twelve officers (建除十二神), with Suit (宜) and Avoid (忌) as the day's decision matrix.
  • Personalisation: bringing in the individual's BaZi, so the date suits the person and not only the calendar.
  • The protocols by event — weddings (嫁娶择日), business openings (开市), moving house (入宅) — and the auspicious hour (择时).

Why Learn It

Stop leaving your milestones to chance.

Gain a lifelong strategic advantage by moving beyond guesswork: understand the mechanics of how time influences outcomes, so you can confidently schedule high-stakes activities — from business launches to medical procedures — without constantly relying on an external consultant or a generic app.

  • Decode the cosmic calendar

    The fundamentals of the Tong Shu and the 12 Day Officers, the first layer every practitioner checks.

  • Personalise your strategy

    Align favourable dates with your own BaZi chart, so the date suits the person and not only the diary.

  • Spot hidden dangers

    Identify and avoid destructive "Clash Days" and negative energy before they are in the calendar.

  • Target specific goals

    Select the precise timing to maximise wealth, marriage and career success.

  • Navigate with confidence

    Stop guessing and start making decisions backed by ancient wisdom — and by the rules behind it.

It is ideal for individuals planning major life events (weddings, business openings, moving house), cultural enthusiasts interested in Chinese metaphysics and folklore, professionals in event planning or consulting who wish to incorporate this traditional service, and complete beginners looking for a structured, practical guide to navigate almanacs and make informed, culturally-grounded timing decisions.

Ultimately, you will learn to create a personalised, step-by-step process for choosing harmonious dates for any significant occasion.
