The constellation is mainly based on the birthday of the new calendar. But the birthday of the new calendar changes every year, so will the constellation change with it?

The constellation is based on the birthday of the new calendar. This is absolutely correct. And everyone's new calendar birthday must be based on the new calendar birthday of the year he was born. This new birthday will remain unchanged for life. Use this new calendar birthday to determine your own constellation. After the constellation is true, it will remain unchanged for life. So I didn't say that birthdays in the new calendar change every year. There won't be any signs that will change.

Please accept it, thank you!
