How to Calculate Kua Number for Male & Female
- Find the traditional year. This calculator uses Li Chun (about February 4) as its primary year boundary: if you were born before Li Chun, use the previous year. The Lunar New Year result is shown for comparison when it differs.
- Add the last two digits of that year, and keep adding until one digit remains. Call it S. Example: 1997 → 9 + 7 = 16 → 1 + 6 = 7.
- Apply the formula for your gender and century (table below).
- Replace 5: male 5 becomes 2, female 5 becomes 8.
| Born 1900–1999 | Born 2000–2099 | |
|---|---|---|
| Male | 10 − S | 9 − S (0 becomes 9) |
| Female | S + 5, reduced to one digit | S + 6, reduced to one digit |
| Result is 5 | Male → 2 (Kun) · Female → 8 (Gen) | |
Worked examples: male, 1997: 9 + 7 = 16 → 7; 10 − 7 = 3 (East group). Female, 2002: 0 + 2 = 2; 2 + 6 = 8 (West group). Female, born January 20, 2004: before Li Chun and Lunar New Year, so 2003 is used: 0 + 3 = 3; 3 + 6 = 9.
What Happened to Kua Number 5?
The Kua numbers map onto the Lo Shu magic square. Eight of its cells hold a trigram, but the center cell, 5, does not. A person cannot be assigned "no trigram", so tradition assigns men to Kun (2, the receptive earth trigram) and women to Gen (8, the mountain trigram). Both are in the West group.

Kua Number Table, 1920–2030
Look up your traditional year. If you were born in January or early February, compare your birth date with the Li Chun and Lunar New Year dates in that row: before both, use the previous row; between the two, the two standards give different years (this calculator uses the Li Chun year as primary and shows the Lunar New Year year for comparison).

Your Kua number (also called the Ming Gua or life trigram number) is a number from 1 to 9, except 5, calculated from your birth year and gender. It places you in the East or West group and sets your four favorable and four unfavorable directions.
How to calculate Kua number for female vs. male (before and after 2000)?
Add the last two digits of the birth year until one digit remains (S). Born 1900–1999: male = 10 − S, female = S + 5. Born 2000–2099: male = 9 − S, female = S + 6. Reduce two-digit results to one digit. Example: a woman born in 1990 has S = 9, 9 + 5 = 14, 1 + 4 = 5, and 5 becomes 8.
Why is there no Kua number 5 in Feng Shui?
Kua numbers come from the Lo Shu square, where 5 sits in the center and has no trigram. When the formula gives 5, men use 2 (Kun) and women use 8 (Gen).
Does the Kua number year start on January 1st or Li Chun (Solar Spring)?
Not January 1. Feng shui sources use Li Chun (around February 4), while the Chinese zodiac is often counted from Lunar New Year. Births before both dates use the previous year. This calculator uses Li Chun as its primary standard. For births between the two dates it shows the Li Chun result first and the Lunar New Year result next to it for comparison.
Can I calculate my Kua number without the calculator?
Yes. Use the formula above, or find your traditional year in the table on this page and read the male or female column. If you were born in January or early February, check the Li Chun and Lunar New Year dates in the same row first.
