Does the constellation look at the new calendar or the lunar calendar?

The constellation is to look at the new calendar.

Constellations were introduced into China from western countries, but in western countries, only the new calendar has no lunar calendar, so constellations are calculated according to the new calendar.

Constellation refers to the place where people are born when the sun passes through the zodiac, but many people's rising or guarding constellations are different, because constellations have been moving and their relative positions are different. When you want to know your horoscope information, you can calculate it according to your date and time of birth.
