Li Chun vs Lunar New Year — Born Hour
Folk zodiac years often turn at Lunar New Year; the Year Pillar usually turns at Li Chun. Related calendars — not the same instant or the same ruler.
Why they diverge
Lunar New Year is the first day of the lunar month (new-moon based). Li Chun is a solar term near 315° solar longitude. Most years they differ by days; near edges they can sit on different stem–branch years.
So someone may already celebrate a Dragon year while the BaZi Year Pillar still belongs to the previous gan–zhi before Li Chun — or the reverse. That is definition, not a bug.
What Born Hour does
After celestial-time calibration, the Year Pillar uses Li Chun as its year boundary. Ziwei’s year stem still follows Lunar New Year convention for the plate. Learn pages and results try to name both rulers.
If your birthday is near either boundary, check Li Chun clock time and local zone — do not rely on a folk-animal sticker alone.
How to read / how not to
When asking “what animal am I?”, ask which ruler. Keep one ruler when comparing charts or annual overlays.
Edge dates are calibration points, not plot twists. See Celestial Time and zodiac topics for deeper context.
