Is beginning of spring the dividing line of Zodiac identification?

Lunar calendar algorithm: the year of the zodiac begins on the first day of the first month.

Taking New Year's Eve as the dividing point, that is, from the beginning of the Lunar New Year (the first day of the first lunar month), the method of calculating the zodiac appeared late, and the earliest record appeared in the Northern Song Dynasty. Now many people agree with this algorithm, and many folklore experts also think that the zodiac should not be calculated according to the 24 solar terms. After all, the Spring Festival is the beginning of the Lunar New Year, and it is also the beginning of the Lunar New Year, so the zodiac naturally starts from the first day of the first month.

Chronology of cadres and branches: counting from beginning of spring on February 4th every year.

Contrary to folklore experts, some astronomical researchers believe that the New Year of the zodiac should begin in beginning of spring. According to reports, the method of taking beginning of spring as the standard of the zodiac began in the Shang and Zhou Dynasties. At present, the folklore used by the people, such as traditional numerology and divination, also takes the "beginning of spring" solar terms as the basis for calculating the zodiac. For example, if numerology depends on a person's date of birth, it must strictly start from spring.
