The two-calendar window in 1917

In 1917, Chinese New Year 正月初一 falls first (1917-01-23) and Lichun 立春 12 days later (1917-02-04). 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 (1917-02-04 16:57:43, 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 1917

Born inside 1917 (after Lichun)? Your Ming Gua: male (2000 − 1917) mod 9 = 2 → Kun 坤 · female (1917 − 2000 + 6) mod 9 = 4 → Xun 巽. Born before Lichun? The formula runs on 1916 — the Kua calculator applies the boundary for your exact birthday.

FAQ

When does the year of the Snake (丁巳) start and end?

By the exact Lichun instant: from 1917-02-04 16:57:43 Beijing to the Lichun of 1918. By the lunar calendar: from Chinese New Year (1917-01-23) to the next new-year new moon. The two definitions disagree about 12 days of 1917 — see the window note above.

Is 1917 a leap month year?

Yes — the lunar year 1917 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 1917?

For births after Lichun: male 2 (坤), female 4 (巽). Births before the exact Lichun instant belong to 1916 and use that year in the formula — most online calculators get early-February birthdays wrong here.
