I was born in1February 6, 958, on the eighteenth day of the twelfth lunar month. What constellation should it belong to?

1958 beginning of spring is February 4th.

Chickens were born before beginning of spring.

You were born after beginning of spring, so you are a dog.

According to the ancient fortune-telling method, beginning of spring is always regarded as the beginning of a new year.

No matter what method is used, the lunar beginning of spring must be strictly defined as the boundary of one year. If beginning of spring was born in the first month, use this year's dry branches; Although he was born in the first month, but the time was before beginning of spring (not yet beginning of spring), then he was born in the year before, and the trunk of the year before served as the annual column. By the same token, although both of them were born in December of the lunar calendar, beginning of spring's former life took this year as the main branch, while beginning of spring's later life will continue to the next year.
