The auspicious day of the zodiac in the yellow calendar

According to legend, the Huangli calendar was created by Emperor Xuanyuan, so it is called the Huangli calendar, which is also commonly known as the "general book" among the people. However, because the word "Shu" in Tongshu is homophonic with the word "lose", it is also called Tongsheng or Tongshun because of taboo. The main contents of the Gregorian calendar are the schedule of the twenty-four solar terms, the good and bad luck of each day, the luck of the zodiac and so on. That is, the ancients recorded their daily likes and dislikes on the calendar as a guide to action. To some extent, China's "Lao Huang Li" ancient calendar is a work of compiling astronomical almanac. It includes many important contents of ancient astronomy in China and is the crystallization of ancient scientific observation and research. The trend of modern Zhouyi gradually began to prevail, even better in some countries in Europe and America. The accelerated pace of people's work and life has led people to choose auspicious days frequently. The use of old calendar books has not decreased, but has increased. Baidu's daily search volume has reached thousands. In the past, when people were traveling, they usually opened the perpetual calendar and simply looked at their likes and dislikes.
