Is the fortune teller's zodiac mouse accurate?

What is Gregorian calendar 1985 February 13? Some people say it's a mouse, some people say it's spring, and some people say it's a cow. What a mess!

If you were born on February 13 in the solar calendar, you are still wondering whether your animal is a rat or a cow. In fact, the fundamental reason is that you don't know what your animal is, or when your animal was determined. A person's belonging is a part of China's cultural tradition. In other words, foreigners have no zodiac signs. Well, since it was decided by our ancestors. Then the date of the solar calendar is obviously meaningless, because the ancestors did not have a solar calendar when determining the zodiac, but determined it according to the lunar calendar. So don't look at the solar calendar, and don't care if it's spring. You just need to make sure whether you were born before New Year's Eve 12 or after 12. In other words, as long as you were born after the first day of the first month (after New Year's Eve 12), what are your attributes?
