How to Use Your Feng Shui Directions
The four favorable directions are, in traditional order, Sheng Qi (vitality and success), Tian Yi (health), Yan Nian (relationships) and Fu Wei (stability). The four unfavorable ones are Huo Hai, Wu Gui, Liu Sha and Jue Ming.
- Bedroom: position the headboard so it points toward Tian Yi or Yan Nian.
- Desk: sit so you face Sheng Qi or another favorable direction while you work.
- Front door: a main door facing a favorable direction is traditionally preferred. Doors are hard to change, so most people start with the bed and desk.
Directions are compass directions measured from the center of the room or home. The compass in your result shows North at the top.
Eight Mansions & Birth Element Explained
Eight Mansions (Ba Zhai, 八宅) assigns every person one of eight trigrams through the Kua number. Kua numbers 1, 3, 4 and 9 form the East group; 2, 6, 7 and 8 form the West group. People in the same group share the same four favorable directions, in a different order.
Manual formula (as used by this calculator): add the last two digits of the birth year until one digit remains (S). For births 1900–1999, male Kua = 10 − S and female Kua = S + 5; for 2000–2099, male Kua = 9 − S and female Kua = S + 6 (reduce to one digit). A result of 5 becomes 2 for men and 8 for women. The full step-by-step method is on the Kua Number Calculator page.
Birth element: the calculator shows the element of your Kua trigram (Kan = Water, Kun and Gen = Earth, Zhen and Xun = Wood, Qian and Dui = Metal, Li = Fire). Traditions disagree on a separate birth-year element, so the calculator does not show one.

Frequently asked questions
What is a Feng Shui calculator and what does it tell me?
This feng shui calculator uses the Eight Mansions (Ba Zhai) method. From your birth date and gender it works out your Kua number (1–9, with no 5), whether you belong to the East or West group, and which four compass directions are traditionally favorable and unfavorable for you.
What is my Feng Shui birth element and Kua number?
Your Kua number comes from the birth year (after the January/February year boundary) and the male or female formula. Each Kua number belongs to a trigram, and the calculator shows that trigram's element as your element. Traditions disagree on how to give the birth year an element of its own, so the calculator does not show a separate birth-year element.
How do I use Eight Mansions (8 Mansions) Feng Shui directions in my home or office?
Traditionally people point the headboard of the bed toward a favorable direction such as Tian Yi (health) or Yan Nian (relationships), and sit at a desk facing Sheng Qi (vitality). Where you cannot change a layout, such as the front door, start with the bed and desk.
Why does biological gender matter in traditional Feng Shui calculations?
Eight Mansions feng shui follows yin and yang: the traditional formula is different for men and women, so the same birth year can give two different Kua numbers. The calculator asks which of the two traditional formulas to apply.
Why does my January or February birthday change the result?
The traditional year does not start on January 1. It starts at Li Chun (around February 4) in the solar calendar, or at Lunar New Year in the lunar calendar. If you were born before both, the previous year is used. If your birthday falls between the two dates, the standards disagree. This feng shui calculator uses Li Chun as its primary standard and also shows the Lunar New Year result for comparison, so you see both.
