The two-calendar window in 1909

In 1909, Chinese New Year 正月初一 falls first (1909-01-22) and Lichun 立春 13 days later (1909-02-04). Anyone born inside that 13-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 (1909-02-04 18:32:47, 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 1909

Born inside 1909 (after Lichun)? Your Ming Gua: male (2000 − 1909) mod 9 = 1 → Kan 坎 · female (1909 − 2000 + 6) mod 9 = 5 → Gen 艮. Born before Lichun? The formula runs on 1908 — the Kua calculator applies the boundary for your exact birthday.

FAQ

When does the year of the Rooster (己酉) start and end?

By the exact Lichun instant: from 1909-02-04 18:32:47 Beijing to the Lichun of 1910. By the lunar calendar: from Chinese New Year (1909-01-22) to the next new-year new moon. The two definitions disagree about 13 days of 1909 — see the window note above.

Is 1909 a leap month year?

Yes — the lunar year 1909 has 13 months with a leap month 2 閏2月, computed by the GB/T 33661-2017 rules (no-zhongqi method, with the 2033-type edge cases handled).

What is my Kua number if I was born in 1909?

For births after Lichun: male 1 (坎), female 5 (艮). Births before the exact Lichun instant belong to 1908 and use that year in the formula — most online calculators get early-February birthdays wrong here.
