Is the constellation calculated by solar calendar or lunar calendar?

Constellations are calculated according to the solar calendar, which is the world Gregorian calendar. Because the world Gregorian calendar originated from Christianity, and the constellation is a system formed by combining celestial constellations with time calendars by Greek astronomers, the division of the twelve constellations must be based on the Gregorian calendar.

365 days a year is divided into almost equal 12 months. Almost every constellation has a month, but they span several months. For example, there are two constellations born in 65438+February, namely Sagittarius (165438+1October 23rd) and Capricorn (65438+February 23rd to 65438+1October 9th).

Because the division of constellations is different from the division of months, the demarcation day of constellations is often around the middle and late of each month, so there will be two constellations adjacent in a month.
