Which of the 60 combinations are considered 'special' or 'abnormal'?

Within the 60 Jia-Zi, certain day combinations carry particularly strong or unusual energetic signatures and are traditionally labeled as 'special patterns' or 'external configurations.' These patterns are not inherently good or bad—their effect depends on the chart’s balance and the person’s useful elements.

Common notable special patterns:
• Kui-Gang (Kui-Gang pattern): Certain days (e.g., Geng-Chen, Geng-Xu, Ren-Chen, Wu-Xu) form a robust, warrior-like energy. People with Kui-Gang often show decisiveness, leadership and authority—but can be headstrong and face interpersonal friction; women may face more marital instability. They do best when the chart supports their strength.
• Noble Day pattern (Ri Gui / Tian Yi): Specific days carry 'heavenly benefactor' energy—holders typically attract helpful patrons and enjoy easier rescue in crises.
• Yang-Blade (Yang Ren / Yang Blade): Extremely strong 'killing' or decisive energy (e.g., a day with the Emperor-Peak branch). It brings courage and forcefulness but risks impulsiveness and external injury; when controlled the person can achieve major success.
• Solitary or Luan patterns (e.g., certain Yin/Si/ etc.): Indicate challenges in marriage or a solitary temperament, often combined with creative talent.
• Major loss days: Traditional lists of days associated with big losses; modern interpretation requires full-chart context—such a day could mean a unique finance profile or a single dramatic loss, but might be neutralized by supporting elements.
• Metal-God or other elemental patterns: Certain day types become auspicious when the chart later encounters favorable luck cycles.
• Yin-Yang mismatch days: A subset of days that can indicate delays or complications in relationships.

These special day signatures often produce pronounced personal traits. Many historical founders and innovators show 'uncommon' day patterns—exceptional people can come from exceptional charts.
