Is the constellation calculated by solar calendar or lunar calendar?

Constellations are calculated according to the date of birth of the Gregorian calendar (solar calendar, national calendar and new calendar).

The date and time of each year are slightly different, and the date of the junction of the two constellations should be determined according to the year and time of birth.
