Do you watch the Spring Festival or beginning of spring in the eight-character year?

Constellations indicate the year, month, day and time of birth. According to the algorithm of the lunar calendar, the year, the month and the day have two characters respectively (for example,1July, the six characters are Ding Younian, Ding Yuewei and Bing Wuri respectively), and the birth time is the same. Traditional astronomy and Yi-ology in China started in beginning of spring instead of watching the Spring Festival, and the day started at midnight (23: 00 ~ 1: 00). Numerology is based on this.
