Here is a reminder to help you determine your Kua or Ming Gua Number.
For men born before 2000: 10 – last 2 digits of the year of birth
For women born before 2000: last 2 digits of the year of birth + 5
For men born after 2000: 9 – last 2 digits of year of birth
For women born after 2000: last 2 digits of the year of birth + 6
I also remind you that feng shui takes into consideration the Chinese solar calendar for which the first day of the year starts on February 3rd, 4th or 5th. So refer to the official calendar if the date of birth falls on these days.
Finally, if the result of your calculation is 5: if you are a man, your Kua is 2, if you are a woman, your Kua is 8.
