SinoWisdomHub
A folk-culture platform for Chinese people, with Traditional Chinese as the primary language.
Liqiu (Start of Autumn) occurs at the exact same instant the Sun reaches a specific celestial longitude — 19:42 in Beijing, 04:42 in Vancouver. Therefore, the Year and Month Pillars are aligned to absolute time, while the Day and Hour Pillars use local time. Most tools simply feed the birth time directly into a calendrical library, which is wrong at this step — and no warning is given if it is wrong. This site lays out each conversion step, allowing you to verify it yourself.
