Feng Shui Eight Mansions Chart

Inputs and result

This eight mansions feng shui calculator takes two inputs: a Gregorian birth date and gender. The birth year turns at the Start of Spring rather than at the lunar new year, the same boundary the BaZi year pillar follows, so a date before the term charts on the previous year. The result gives the life trigram with its name, Luoshu number and element, whether it belongs to the East or West group, the four directions of its own group as favorable and the other four as unfavorable with the touring star each carries, and a nine-palace direction grid.

Mnemonic and examples

One mnemonic does the work. Add the four digits of the birth year until a single digit remains: 1985 gives 1 plus 9 plus 8 plus 5 for 23, then 2 plus 3 for 5, so the year counts as 5. A male chart takes 11 minus that digit, a female chart takes it plus 4; a result above 9 has 9 subtracted, and a result of 5 becomes Kun 2 for a male chart or Gen 8 for a female chart. The 1985 male chart is 11 minus 5, which is Qian 6.

Year by year

That single digit rises by one each year, so the male number falls by one and the female number rises by one, one palace at a time. The 1985 male chart is Qian 6, the 1986 male chart reaches 5 and rests on Kun 2, and the 1987 male chart is Xun 4. Male and female charts born in one year match only in a year whose digit is 8: 11 minus 8 is 3, and 8 plus 4 is 12, which becomes 3 again once 9 is subtracted. 1997 is such a year, and both charts read Zhen 3.

East-West groups and grid

The grouping follows the Later-Heaven palace: Kan 1, Zhen 3, Xun 4 and Li 9 form the East group, and Qian 6, Kun 2, Gen 8 and Dui 7 form the West group. The four directions of the same group are the favorable four, so every East group chart reads North, East, Southeast and South, and every West group chart reads Northeast, Southwest, West and Northwest. The grid on the result page runs south at the top and east on the left, the old orientation, with the life trigram itself in the center cell, the eight palaces on their Luoshu positions, and each palace marked with the star it receives.

Touring stars and related tools

Those stars come from the touring-star verse run on the life trigram. Fu Wei always sits in the life trigram's own palace, and the other seven palaces take one star each in the Earlier-Heaven round of Qian, Kan, Gen, Zhen, Xun, Li, Kun and Dui. The same-group four take Sheng Qi, Tian Yi, Yan Nian and Fu Wei and the opposite four take Jue Ming, Wu Gui, Liu Sha and Huo Hai, so a Qian 6 chart puts Liu Sha on Kan, Tian Yi on Gen, Wu Gui on Zhen, Huo Hai on Xun, Jue Ming on Li, Yan Nian on Kun and Sheng Qi on Dui. What each star governs, and how the eight are placed against doors and beds, is not on this page. Beyond direction, the facing degrees of the twenty-four mountains are on the Twenty-Four Mountains Luopan Calculator page, the twenty-year cycle on the Feng Shui Nine Periods Lookup page, the star flying into a palace for a year or month on the Feng Shui Purple-White Stars Chart page, and the five-element pattern of a birth moment on the BaZi Chart page. What this page gives is a grouping, its direction reading and the eight touring stars, not a reading of health, money or family.

East group and West group directions

The life trigram falls on one of the eight palaces by its Luoshu number: Kan 1, Zhen 3, Xun 4 and Li 9 form the East group, and Qian 6, Kun 2, Gen 8 and Dui 7 form the West group. The four directions of the same group are the favorable four. Trigram, Luoshu number, direction and element are listed below.
