The twelve constellations are based on the lunar or solar calendar, and the constellations are based on the lunar or solar calendar.

Constellations are made by foreigners. They don't understand the China lunar calendar, so they can only follow the solar calendar. Constellation is determined by the Gregorian calendar date, and the Gregorian calendar date should be used to query the constellation. If the lunar calendar date is used, the corresponding year should be provided so that the lunar calendar date can be converted into the solar calendar date for query. You fill in the year. I can help you.

I attach the date table of 12 constellation below for your inquiry.
