Eight Mansions calculator: questions and method
How does the Eight Mansions calculator work?
The calculator derives a personal Life Gua (Kua number) from your birth details and the traditional male/female calculation category. The birth year follows the solar-year boundary at Li Chun, rather than January 1 or Lunar New Year. It maps eight compass directions to traditional Eight Mansions classifications. These are cultural interpretations, not evidence of health, financial or relationship outcomes.
Is a personal Kua number the same as a house gua?
No. Personal Life Gua comes from birth information; house gua is classified by the dwelling’s sitting direction, opposite its facing direction. A person and a home can therefore have different gua. A personal direction table alone does not establish the home’s house gua or Flying Star natal chart.
Is this the same as a bagua map calculator?
No. A bagua map describes sectors on a floor plan. Compass-based methods align those sectors with measured compass directions; entrance-aligned BTB methods use the entrance side as a reference. Neither should be silently substituted for the other. This tool’s personal direction table uses compass directions and does not automatically align a bagua map to your floor plan.
What do the four favorable directions mean?
Sheng Qi, Tian Yi, Yan Nian and Fu Wei are the four traditionally favorable classifications assigned through Life Gua. Their translated names and associations are traditional labels, not medical advice or guarantees of wealth, longevity or relationships. Keep safe access, ventilation and comfortable furniture placement ahead of symbolic direction preferences.
Is Period 9 the same as the annual center star?
No. Period 9 names the 20-year cycle from 2024 to 2043 in the convention used here. Annual stars form a separate yearly layer, so Period 9 does not mean star 9 occupies the center every year. A home’s natal chart also needs its construction-period and sitting/facing information; the current period alone is insufficient.
Where are the annual Flying Stars in 2026?
For the 2026 annual chart used by this site, star 1 is in the center, star 9 in the southeast and star 5 in the south: 1 White at the center, 9 Purple in the southeast and 5 Yellow in the south. This is a dated annual layer, not a complete home chart or a prediction of prosperity. Around Li Chun, confirm which annual chart applies; do not postpone necessary repairs on the basis of a star label.
