Is the zodiac according to the lunar calendar or beginning of spring?

China Gregorian calendar uses beginning of spring to determine the zodiac.

"Lunar calendar" is the lunar calendar used in the Han Dynasty, with beginning of spring as the boundary, beginning of spring as the first of the 24 solar terms, and beginning of spring as the zodiac sign.

According to the China calendar, this genus is divided into beginning of spring. The division of the two zodiac signs is not based on the solar calendar's 65438+1 month's1,nor on the first day of the first lunar month, but on the beginning of spring solar terms in the twenty-four solar terms.

Both traditional numerology and astrology take "beginning of spring" as the basis for calculating the zodiac. Including Mr. Zhan Ren, a folk now, has always followed the traditional zodiac method. Because the zodiac is the same as the earthly branch, it can't be determined by the current Spring Festival. For convenience, some people decide the zodiac directly according to the Spring Festival, so the tradition is gradually forgotten by many people, and the definition of the zodiac is also controversial.
