What is the constellation on April 22nd?

The constellation is based on the Gregorian calendar birthday of the year in which you were born, and has nothing to do with the Gregorian calendar in subsequent years. You have to quote the year of your birth before you can check the solar calendar of your birth year. But according to your birthday in the lunar calendar, your birthday in the solar calendar should be in May-June. You should provide three constellations, and then sit in the right position after converting the solar calendar.
