Is the zodiac based on the lunar calendar or beginning of spring?

The rotation point of the ecliptic is the beginning of spring! But for the convenience of calculation, it is generally considered as the Spring Festival! The basis of the zodiac is the chronology of the branches. The zodiac corresponds to the twelve earthly branches. Corresponding to the ugly mouse, cow, tiger and rabbit.

The lunar calendar in our country is the lunar calendar. Is to consider the movement of the sun and the moon at the same time. Among them, 24 solar terms return completely according to the sun. Therefore, the solar calendar date of each solar term is basically certain, while the lunar calendar date is far apart. Every month of the lunar calendar is based on the moon's profit and loss.

The new moon is always on the first day. The beginning of a year is the beginning of spring. When we say "Xu Bing Year" and "Ding Hai Year", we should start from beginning of spring. But beginning of spring has nothing to do with the moon phase. The lunar month must start from the first day, that is, from the new moon.

In ancient China, there were actually two calendars, one was based on the movement of the moon, that is, the "lunar calendar"; The other is based on the movement of the sun, which is the ancient "solar calendar". The 24 solar terms are determined according to the movement of the sun. Beginning of spring is the first day of the year in the ancient solar calendar, and the zodiac (called the twelve earthly branches in ancient times) is determined accordingly, which has nothing to do with the lunar calendar.

If beginning of spring was born on that day, the first step is to find out on the calendar when the solar terms were paid on the day when beginning of spring was born. Step 2: Know your birthplace and exact date of birth. The above two items can be converted into the real solar time when you were born on some websites (originally only Beijing time).

The third step is to compare it twice. The year before the solar term is the Chinese zodiac, and vice versa.
