Why is November called Winter Moon?

The date of the lunar calendar is not fixed, but the winter solstice is always 1 1 month, so 1 1 month is called the winter month. When there is no leap month in a year, the 1 1 month in the lunar calendar is the first 1 1 month in a year. Because it is the winter solstice month in the 24 solar terms, the 1 1 month in the lunar calendar is also called the winter month, and it is also called midwinter and mid-winter.

According to the China lunar calendar, the solar term from winter solstice must appear in 1 1 month. If there is an error in the operation, it should be adjusted by the setting of leap month. According to Records of the Historian, Huangdi's magical strategy of obtaining Baoding was to get the punishment of Heaven at the age of one, the new moon and the winter solstice and start over. That is to say, in the Yellow Emperor, the winter solstice was regarded as New Year's Day (new moon), and the November of the lunar calendar was also called the winter moon.

In addition to the winter moon, there are many other nicknames for November in the lunar calendar. These names come from the wisdom of the ancients and are often full of exquisite and beautiful poetry. The Book of Rites says: The mid-winter moon is called the long moon. Zheng Xuan's annotation is: Chang, still full. Therefore, the November of the lunar calendar is called the long month.

Kong also commented on this: it is said that this month is a month of enrichment, and it is necessary to enrich everything and not start. Sun Xidan's collective plan is to be constant and generous. When time is closed and smooth, it is said that life is smooth, and it is also said that it is against the sky. According to the sequence of winter, November is also called midwinter, and there are also sayings such as lucky month, bitter month (grass grows green) and long Qian Yue.

In ancient China, the twelve-tone method was adopted, that is, an octave was divided into twelve incomplete semitones by three-point gain and loss method. The legal system from low to high is: Huang Zhong, Lu Da, Tai Cong, Jia Zhong, Gu Xi, Zhong Lu, Yan Bin, Lin Zhong, Yize, Nanlu, Wushe, Ying Zhong, and the twelve laws are matched with December.
