In the Eight House Feng shui System your Kua number (or Gua number) is used to determine your favourable and unfavourable direction and sector. Therefore it is crucial to know how to calculate your Kua number (or Gua number) correctly.

I am going to use the example of a Mary who was born on the 25th of January 1965.

The Kua number is essentially derived from the year of birth. More accurately it is the year of birth based on the Chinese Solar or Yang or Xia Calendar’s year of birth.

In the Gregorian calendar, the year starts on the 1st of January. In the Chinese Solar Calendar the years starts between the 3rd and 5th of February. This is often called “Li Cun” or “Spring Arrives” and you can determine the exact date for each year by referring to the Ten Thousand Year Calendar.

Please note that the Chinese Solar Calendar is different from the Chinese Lunar Calendar whose first day of the year varies between late January and late February every year. The first day of the Chinese Lunar Calendar is also the much celebrated Chinese New Year day.

In 1965 the first day of the solar year falls on the 4th Feb. Since the birth day is before the 4th of February 1965, Mary is deemed to be born in the previous year which is 1964. If Mary was born on or after the 4th Feb, then she is deemed to be born in 1965.

Here is how you calculate the Kua number for Mary, a female.

Take the last two digit of the year which is 64 and add them together

6 + 4 = 10

Reduce the result to a single digit by adding them together

1 + 0 = 1

Add 5 to the result gives 6 which is Mary’s Kua Number.

5 + 1 = 6

The steps to calculate the Kua Number for a guy, say called John, differs slightly.

As before, you take the last two digits and add them together. Then add the result to reduce it to a single digit (if the result is 10 or more).

But instead of adding 5, you subtract from 10.
In this example it is

10 – 1 = 9

Thus John’s – a male – Kua Number is 9.

This method works for anyone born before the year 2000. If you do not like mathematical calculation you can simply read your Kua number of my Kua Chart.

The concept of Gua number stems from the Feng Shui Eight Mansions system.

In this system, all of us have a Gua number that is dependent on our date of birth and sex. You can find out you Gua number by clicking on the link below.

In the Eight Mansions system, it is believed that we are imprinted with the energy of the time of our birth. Based on your ‘imprint’, certain directions are favourable and others are not. This ‘imprint’ is expressed as our Gua number.

How do we make use of this Gua number?

You should sleeping and sit facing the directions that are favourable to you. Suppose you are a male with the Gua number 7. Your favourable directions are NW, SW, NE and W.

Therefore you should sleep with the crown of your head pointed towards one of these directions. For sitting the point of reference is different. Instead of using the crown of your head, you should use your face. It is simply the direction that your face is facing when seated!

If you look at the Gua number carefully, you will notice that there are meanings attached to each of the favourable and unfavourable direction. For a Gua number 7 person, NW is his prosperity direction, SW is health and so on. How do we use them?

The simple answer is this. If you are aspiring for more money, for a promotion or better business, then you should try to face the Sheng Qi (Living Qi) or Prosperity direction.

If you health is not so great, then try the Tian Yi (Heavenly Doctor) or Health direction. If your social life is in a doldrums or you lack good people interaction skills, you should try to face your Nian Yen or Relationship direction.

Finally if you have everything that you need and just want a peaceful, uneventful life, then try the Fu Wei or Stability direction!

In the Eight Mansions system, the house also has a Gua number which is determined by the sitting direction of the house. There are favourable and unfavourable sectors. For maximum effect with the Eight Mansions system, you should not just face your favourable directions but also locate yourself in a favourable sector.
