Feng Shui Kua Number Calculator
Your personal Kua number and favorable Feng Shui directions, computed from the real traditional formula based on your birth year and gender — the classical starting point for orienting a home or workspace according to Feng Shui practice.
Once your Kua number is known, classical Feng Shui assigns you four favorable and four unfavorable compass directions for that number — traditionally used to orient a bed, desk, or front door — computed here from the real formula based on your exact birth year and gender rather than approximated.
The formula differs for men and women specifically because the traditional calculation reflects different starting reference points by gender — both are computed correctly here from your real birth year rather than a single unisex approximation.
Frequently Asked Questions
Why does the Kua number formula change for people born in 2000 or later?
The classical formula uses a different base number on either side of the year 2000 — a fixed part of the traditional calculation itself, not an approximation.
Why is there no Kua number 5?
5 isn't a valid final Kua number — when the calculation reduces to 5, it's reassigned to 2 for men and 8 for women.
What's the difference between East Group and West Group Kua numbers?
Kua numbers 1, 3, 4, and 9 form the East Group; 2, 6, 7, and 8 form the West Group. Each group has its own four favorable directions.
Why might my Kua number differ from another calculator if I was born in January or February?
Some Feng Shui sources apply a Chinese Lunar New Year cutoff rather than the plain January 1st boundary. This tool deliberately uses the plain Gregorian year rather than assert an unverified cutoff rule.
Does the Kua number formula depend on gender?
Yes — the same birth-year digit sum is combined differently depending on whether you select male or female.
