Practical Analysis of Avoiding Clashes and Combinations in Selecting Birthday Dates for Elderly

The client is a lady approximately 55 to 60 years old, currently in the mid-phase of the Bing Zi (丙子, Bing Zi) Da Yun (decade luck cycle), which is a stable period. Her family places great importance on traditional culture, especially the selection of auspicious dates for birthday celebrations. The issue at hand is that the originally scheduled auspicious birthday date needs to be postponed due to special reasons. The family is concerned whether changing the date might bring unfavorable effects, thus seeking professional metaphysical guidance to ensure the birthday proceeds smoothly.

The client has a steady personality and values balance and harmony in life, particularly resonating with the concepts of Yong Shen (favorable elements) and Ji Shen (unfavorable elements) in metaphysics. Based on a preliminary understanding of her BaZi chart, the family wishes to clearly identify which days and time periods' clashes and combinations must be avoided when adjusting the birthday date, so as to prevent activating any Ji Shen and ensure the birthday banquet is auspicious and joyful.

Analyzing the client’s Four Pillars (Heavenly Stems and Earthly Branches), the Day Master is Bing Yin (丙寅), indicating a fire element that is relatively strong, symbolizing abundant inner fire and vitality. Her pattern is Qi Sha (Seven Killings), which shows that external environments and changing factors have a significant influence on her, requiring careful regulation to avoid clashes. The Yong Shen (favorable elements) are water and metal, meaning these elements are crucial for balancing and supporting her chart, while wood is the Ji Shen (unfavorable element), whose excessive presence disrupts the chart’s balance and brings negative effects.

Currently, she is in the Bing Zi Da Yun, which is a stable luck phase, suitable for maintaining achievements rather than taking risks. The Liu Nian (annual fortune) is Bing Wu (丙午), which relatively strengthens the fire element; however, since Bing Wu interacts smoothly with the Bing Zi Da Yun, the overall environment supports steady progress. Considering these factors, when adjusting the birthday date, special attention should be paid to avoiding wood element clashes to prevent activating the Ji Shen and destabilizing the Da Yun.

Additionally, the Bing Yin Day Master inherently carries Yin wood (寅), but since wood is the Ji Shen, it is necessary to avoid selecting days or time periods with wood-related clashes, especially those involving Earthly Branches like Hai (亥) water and Si (巳) fire, which may indirectly affect wood’s activity and cause adverse effects.

Regarding the need to postpone the birthday date, the key is to avoid clashes related to the wood element. Since wood is the Ji Shen, if the newly chosen auspicious day or time contains wood clashes, it will activate the unfavorable element in the chart, potentially causing health or fortune setbacks. In particular, it is important to avoid Hai-Kang (亥亢) clashes, Yin-Shen (寅申) clashes, and other wood-related penalties and clashes to prevent exacerbating wood’s negative influence.

Furthermore, as the Yong Shen are water and metal, date selection should favor Heavenly Stems and Earthly Branches containing water and metal elements to help neutralize and support the fire-biased Day Master, thereby harmonizing the overall balance. For example, choosing days with Ren (壬) water, Gui (癸) water, or Geng (庚) metal, Xin (辛) metal can effectively provide support while avoiding wood-related clashes.

During the adjustment period, it is advisable to avoid strong wood-fire clashes in the Liu Nian or Da Yun, especially when Earthly Branches such as Wu (午), Si (巳), and Yin (寅) — which are fire and wood strong branches — appear. Such combinations should be avoided to prevent disorderly clashes with the Bing fire Day Master. Maintaining stability between the Da Yun and Liu Nian environments and selecting dates that harmonize with the Yong Shen will ensure the birthday event proceeds smoothly and auspiciously.

Practically, it is recommended to first select days within the current Bing Zi Da Yun and Bing Wu Liu Nian that contain water and metal Heavenly Stems and Earthly Branches, avoiding days with Yin (寅), Mao (卯) wood, and Hai (亥) water clashes. For example, days containing Gui (癸) water or Geng (庚) metal are suitable as new birthday dates, as they can effectively harmonize the chart. If time permits, selecting months with abundant water or metal according to the chart’s Yong Shen direction for the event is advisable.

For time period (hour) selection, choosing Gui (癸) water hours or Geng (庚) metal hours is preferable, while avoiding wood-strong hours such as Yin (寅) hour. This not only enhances the supportive effect of the Yong Shen but also prevents activation of the Ji Shen wood, ensuring a stable energetic environment on the birthday and avoiding unfavorable changes. This principle can also be applied for similar important events in the future.

Additionally, it is important to avoid Earthly Branch clashes with the client’s birth year pillar Geng Xu (庚戌) and month pillar Ren Wu (壬午), especially those involving Chen (辰), Xu (戌), Chou (丑), and Wei (未) which form clashes and combinations. By avoiding these unfavorable clashes, the smoothness and safety of the birthday celebration will be greatly enhanced.

In practice, a common mistake is simply avoiding inauspicious days without considering the coordination of Yong Shen and Ji Shen. Accurate metaphysical judgment requires integrating the Day Master’s strength, the Yong Shen and Ji Shen, and the interactions of Da Yun and Liu Nian to precisely grasp the impact of clashes and combinations. Especially in this case with a fire-biased Day Master, where wood is the Ji Shen and water and metal are the Yong Shen, neglecting wood clashes during date selection can easily cause health and fortune fluctuations.

Moreover, individuals with a strong Day Master should maintain a stable and conservative mindset when adjusting important dates, avoiding rash or frequent changes. Leveraging the stability of the Da Yun and Liu Nian, and adhering to the principles of water and metal support while avoiding wood clashes during date selection, will ensure the birthday celebration is auspicious and as desired.
