What is a Kua number?

In Eight Mansions (Bát Trạch) feng shui, a Kua number is a personal index derived from birth year and gender. It places you in either the East Life Group or the West Life Group and pairs you with four supportive directions and four challenging ones. Classical teachers use names such as Sheng Qi, Tian Yi, Yan Nian, and Fu Wei for the supportive set, and Jue Ming, Wu Gui, Liu Sha, and Huo Hai for the draining set.

The method is traditional, not scientific, and it is not medical, architectural, or financial advice. People use it as a cultural lens when arranging a bed, desk, or conversation about home energy. Vision Studio’s Feng Shui House app takes the next step: showing those directions on an actual floor plan so the conversation stays tied to rooms you can walk through.

Because solar terms matter, births near early February deserve care. Li Chun (Lập Xuân) marks the conventional start of the solar year for many Ming Gua calculations. Entering month and day lets this tool adjust quietly; we only show the summarized Kua and directions — never intermediate arithmetic.

Gender appears in the classical formula historically used in Eight Mansions. We ask for it solely to compute the traditional result and do not save the form. Rate limits apply by IP to keep the public tool healthy.

If two partners have different life groups, that is common. Shared spaces often compromise with furniture facing, headboard orientation, and which person spends more waking hours in a room. The calculator cannot see your walls; the app is built for that layer.
