What is the constellation on February 7th?

Hello, the constellation is a fortune-telling thing for westerners. Because westerners don't have a lunar calendar, we should first convert the birthday of the lunar calendar into the solar calendar, and then look up the constellation table.

? If it is February 7 in the solar calendar, it is Aquarius;

? If it is February 7th of the lunar calendar, it is impossible to accurately convert the solar calendar month because the year of birth is not mentioned, so it is impossible to find out what constellation it is. ?
