Feng shui is one of the myriad ancient Chinese modalities that were cultivated to improve your health and prosperity in life. Other practices include herbs, acupuncture, and acupressure. Although feng shui works the most directly in your environment, it also works in tandem with these other practices, like astrology and numerology, to improve the overall qi (life force energy) for you and your family. 

What Is a Feng Shui Kua Number?

The feng shui kua number is used in the traditional and classical feng shui schools, while practitioners of other schools may use other systems like the Nine Star Ki, which is similar. Your kua number is also sometimes referred to as the Eight Mansions, the Eight House system, or your personal trigram.

Feng shui practitioners use your feng shui kua number in their evaluation of you and your home. Your kua number can give information, direction, and insight regarding ideal directions for your bed, your desk, your house, and also compatibility with other people, including a life partner.

The fun part about calculating your feng shui kua number is that it’s pretty easy and accessible for anyone. Keep reading to learn how to find your personal trigram!

How to Calculate Your Feng Shui Kua Number

Before we start with the calculations, there are some things to watch out for. 

The Chinese Calendar

First, this system is based on the Chinese calendar, which has a different first day of the year than Western calendars. The year starts on or around February 4 (depending on the year), which is considered the first day of spring on the Chinese calendar. (Just to make it a little more confusing, this is not the same day as Lunar New Year.)

This means that if you were born before February 3, you are definitely the year prior. For example: 

  • If you were born January 17, 1980, you would be considered born the year prior, so please use 1979 in your calculations.
  • If you were born February 2, 1963, you would be considered born the year prior, so please use 1962 in your calculations.

It’s a bit more tricky if you were born on February 3, 4, or 5. If this is the case, it’s helpful to consult a Chinese almanac for the exact transition time based on your birthdate and time for an accurate calculation. 

Identifying Gender

This system is also calculated differently depending on the gender of the individual. Typically, and historically, you use the gender you were assigned at birth. However, we recommend you use the gender you identify with or identify with the most at the time of your calculation. 

Calculating Your Kua Number

You can calculate your feng shui kua number by using your year of birth. This does require a little bit of math, so don’t be shy about pulling out your calculator. 

Add up all four digits of your birth year

  • If you still have two digits, add those two digits together to reduce to a one digit number
  • Don’t forget what we mentioned above for those born between January 1 and February 5. 

If you identify as female: 

  • Add 4 to that number
  • If you have a two-digit sum, add those two digits together to reduce to a one digit number
  • The final single digit number is your feng shui kua number
  • note: If you get 5, your feng shui kua number is 8

Or if you identify as male:

  • Subtract that number from 11. 
  • If you have a two-digit sum, add those two digits together to reduce to a one digit number
  • The final single digit number is your feng shui kua number
  • note: If you get 5, your feng shui kua number is 2

Examples

If your birth year is 1989 and you identify as female: 

  • Add all the digits of your year: 1 + 9 + 8 + 9 = 27
  • Reduce to a single digit: 2 + 7 = 9
  • For females, add 4 to that number: 9 + 4 = 13
  • Reduce to a single digit: 1 + 3 = 4
  • Your feng shui kua number is 4 

If your birth year is 1972 and you identify as male:

  • Add all the digits of your year: 1 + 9 + 7 + 2 = 19
  • Reduce to a single digit: 1 + 9 = 10
  • Reduce to a single digit: 1 + 0 = 1
  • For males subtract that number from 11: 11 - 1 = 10
  • Reduce to a single digit: 1 + 0 = 1
  • Your feng shui kua number is 1
