People whose birthdays are on 1 month 1 day are constellations.

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 the first day of January in the solar calendar, it is Capricorn;

If it is the first day of the first month of the lunar calendar, it is impossible to accurately convert the month of the solar calendar because it does not say the year of birth, so it is impossible to find out what constellation it is.
