March 22nd, auspicious day of the ecliptic.

Today's solar calendar pays attention to the "Tang Ming" god, which belongs to the sun god of the ecliptic, and meets the conditions for the establishment of an auspicious day of the ecliptic.

Auspicious days of the zodiac are divided into big auspicious days and small auspicious days. The zodiac day is a row of twelve satellites, headed by the moon. Because it is not universal, it is called Xiao Huang Dao Day. Six days of the ecliptic, six days of the underworld: construction, fullness, peace, closure, black, elimination, danger, determination, adherence to the yellow, success, opening, closure and breaking. According to the law of the influence of celestial bodies and astrology on human beings, the ancients formulated the ecliptic underworld day, which provided some references and choices for China people to choose a day to avoid disaster. This auspicious culture has been deeply rooted in the thoughts of China people since ancient times.
