Auspicious days of the zodiac are divided into big auspicious days and small auspicious days. The zodiac is a line of twelve satellites headed by the moon. Because it is not universal, it is called Little ecliptic Day. There are six ecliptic days and six underworld days: construction, fullness, leveling, closing and black, clearing, danger, yellow determination and execution, success and opening can be used, closing and breaking are not equal.

The auspicious day of the zodiac is a unique term in China's traditional calendar "Huangli" (perpetual calendar), which refers to a day when everything goes well. Among the twelve zodiac signs, "Qinglong, Tiande, Yutang, Siming, Tang Ming and Jingui" are called "Six Zodiac Days" ("Eliminating Danger, Deciding, Persistence, Realizing and Opening" among the twelve duty days is called "Little Zodiac Day"). When the six gods of the zodiac are on duty, everything is appropriate, and they don't avoid evil. This is called "auspicious day of the zodiac".
