Is the zodiac based on the lunar calendar or the solar calendar?

Traditionally, it is calculated according to the solar term "beginning of spring", of course, it is the lunar calendar. Before beginning of spring, it was considered as a year of the zodiac in the previous year, and after beginning of spring, it was considered as the New Year in the zodiac. For example, February 4th, 2009 is beginning of spring Day, so animals born before February 4th are still "rats", and people born between February 4th and the next beginning of spring are cows. More specifically, it is calculated by the time of spring break. The specific time of spring break in 2009 is 1: 08+02 in the early morning of February 4th in the solar calendar and 1: 08+02 in the early morning of the first lunar month, so rats were born before this point, and cows were born after this point. ...

Nobody seems to pay that much attention now. I wish I hadn't met such a hurry when I was born! For example, people born in May and June will never encounter spring, nor will they worry about the chaos of the zodiac.

Zodiac is a tradition in China, so we should follow the traditional calendar in China. If we follow the solar calendar, it will be meaningless, just like a Chinese wedding worships heaven and earth at a priest in a church. Grandstanding is ok. To maintain national customs and totem worship, we should follow the tradition, but not be superstitious. Liking tradition does not mean superstition.
