The two-calendar window in 1931

In 1931, Lichun 立春 falls first (1931-02-05) and Chinese New Year 12 days later (1931-02-17). Anyone born inside that 12-day window gets a different zodiac animal and year pillar depending on which convention their tool follows — BaZi practice switches at the exact Lichun instant (1931-02-05 02:40:50, Beijing), folk calendar practice at the new moon. This is not an edge case we gloss over — it is the single most common source of wrong zodiac years, and our engine comparison tool shows it live with three engines side by side.

Your Kua number for 1931

Born inside 1931 (after Lichun)? Your Ming Gua: male (2000 − 1931) mod 9 = 6 → Qian 乾 · female (1931 − 2000 + 6) mod 9 = 9 → Li 离. Born before Lichun? The formula runs on 1930 — the Kua calculator applies the boundary for your exact birthday.

Is 1931 a leap month year?

No — the lunar year 1931 has 12 months and no leap month.

What is my Kua number if I was born in 1931?
