Determining a Kua number involves a straightforward calculation based on one’s birth year and gender. For males born before the year 2000, subtract the last two digits of the birth year from 10. If the result is a single digit, that is the Kua number. If the result is a two-digit number, add those digits together to arrive at a single-digit Kua number (with the exception of 5, which becomes 2 for males). For males born after 2000, the last two digits are subtracted from 9. For females born before 2000, add 5 to the last two digits of the birth year. Again, reduce any double-digit result to a single digit (with 5 becoming 8 for females). For females born after 2000, add 6 to the last two digits. For example, a male born in 1985 would have a Kua number of 5 (10 – 85 = -75, 7 + 5 = 12, 1 + 2 = 3, which becomes 3. 5 is 2 for males). A female born in 1992 would have a Kua number of 1 (92 + 5 = 97, 9 + 7 = 16, 1 + 6 = 7, which becomes 7.)
This numerical value plays a significant role in certain traditions, offering insights purportedly aligned with auspicious directions, colors, and numbers for individuals. Rooted in ancient Chinese philosophical principles, its application extends to various aspects of life, from home design and arrangement to career choices and relationships. Historically, understanding these individual alignments was considered crucial for harmonizing with the environment and achieving greater well-being.
