Should we look at the date of birth of the lunar calendar or the lunar calendar according to the constellation?

Gregorian calendar, because constellation is a concept related to the division of earth orbit.

Strictly speaking, the first constellation in a year is Aries, and it will be nearly a month from the vernal equinox to the next "Qi" (among the 24 solar terms, odd solar terms are called "Festival", even solar terms are called "Qi", and the Spring Festival is the fourth, that is, "Qi" in Grain Rain).

Taurus is a month from Grain Rain to Xiaoman.

And so on. However, the intersection time of the 24 solar terms is complicated (related to the regression period of the direct point of the sun), so the constellation is generally defined as

Aries March 2 1 ~ April 21

Taurus April 22nd to May 2nd1

Gemini may 22 ~ June 23

Cancer: June 24th to July 23rd.

Leo July 24 ~ August 23

Virgo August 24th to September 23rd.

Libra September 24th ~ 65438+1October 22nd (also known as Libra).

Scorpio 65438+1October 23rd ~165438+1October 22nd.

Sagittarius165438+1October 23rd ~ 65438+February 20th (also known as Sagittarius).

Aries 65438+February 21~ 65438+1October 19 (also known as Capricorn)

Aquarius 65438+1October 20th ~ February 20th

Pisces February 21~ March 20

All the above dates are in Gregorian calendar. Because they are all rough calculations, there are different rules for individual dates, but the difference will not exceed two days.
