What should I think of the yellow calendar?

The main contents of the Gregorian calendar include: twenty-four solar terms, avoiding bad luck, rushing evil, combining evil, radio, dry branches, twelve gods, on duty, fetal gods, stars, moon phases, evil spirits, jealousy of Peng Zu, six splendors, nine planets, fleeting time, traditional Chinese medicine, mysterious nine planets, weeks, zodiac signs, directions and so on.

In the Gregorian calendar, "Qinglong, Tiande, Yutang, Siming, Tang Ming and Jingui" in the Twelve Gods are called the Six Zodiac Days, and "except, danger, determination, persistence, success and opening" in the Twelve Zodiac Days are also called the Little Zodiac Days. When the six gods of the zodiac are on duty, everything is suitable and does not avoid evil spirits, that is, "the zodiac is auspicious."

At that time, the contents that should be avoided when waiting for the weather recorded in Japanese books involved not only daily activities such as marriage and travel, but also military affairs such as attacking and sending troops.

In addition to calculating calendars and observing astronomical phenomena, the official astronomical institutions of past dynasties were also responsible for handling selection matters. For example, in the Eastern Han Dynasty, Tianguan's duties included: "When the country offers sacrifices, funerals and weddings, it should play the taboos of auspicious days and festivals in time."

Later, in the official astronomical institutions, there was a department to deal with this kind of affairs. In Song and Yuan Dynasties, it was called Sanshi Division, and in Qing Dynasty it was called Missed Division. At the beginning of the Qing Dynasty, the responsibilities of this department were: "Look at the architecture of the inner and outer palaces, look at the geomantic omen of mountains and hills, promote marriage, choose auspicious days, adjust the quality of pots, manage the entrance of buildings, and pay attention to the direction of setting up special schools."
