How do I find my Kua number?

Take your Lichun-rule birth year (the year flips at the exact Lichun instant around February 4), then apply the formula: male (2000 − year) mod 9, female (year − 2000 + 6) mod 9, with remainder 0 counting as 9. Or enter your exact birthday in the Kua calculator and the boundary is applied for you.

Why do calculators disagree about my Kua number?

Most commonly because you were born in January or early February: naive tools use the calendar year, while the classical rule flips the year at the exact Lichun instant. Two conventions for female Kua 5 also exist (five yellow寄艮 or寄坤); we display the Gen convention and label it.

Where do these numbers come from?

The same WASM kernel that powers this site and its public API. The eight-direction star assignments are computed by two independent classical methods — the Dayou-nian verse and the six-line transformation — and every year in this table passed an 8/8 cross-check before generation.

Kua Number by Birth Year 命卦逐年表

Every birth year 1901–2100 with its Ming Gua 命卦 (Kua number) for male and female births, the group (East/West Four), and the exact Lichun instant that decides January–February birthdays. All kernel-computed — the same binary as the public API.

Male formula (2000 − year) mod 9 · female (year − 2000 + 6) mod 9 · remainder 0 counts as 9 · year flips at the exact Lichun instant

Born in January or February? Your Kua year flips at the exact Lichun instant (around February 4) — don't trust the calendar year. The Kua number calculator applies your exact birthday and prints the instant it used.
