Twenty-four specific festivals represent seasonal changes in the calendar of twenty-four seasons. Ganzhi calendar is a kind of solar calendar, also known as solar calendar, which is the product of ancient agricultural civilization and profound. It is determined according to the law of the earth's revolution around the sun, and it is a calendar that completely conforms to the laws of astronomical phenomena.
Although it does not correspond to all parts of the country, it can be used as a reference for climate change in four seasons. Since ancient times, dry calendars are still popular in books such as perpetual calendars, which are used for astrology, geomantic omen and numerology. It is an important part of the long history and culture of the Chinese nation and embodies the historical and cultural essence of Chinese civilization.
Twenty-four solar terms are not only the time criterion promulgated by successive governments, but also the compass to guide agricultural production and to predict cold, warm, snow and rainy days in people's daily life. Twenty-four solar terms accurately reflect seasonal changes, which are used to guide agricultural activities and affect the food, clothing, housing and transportation of thousands of households. The twenty-four solar terms scientifically reveal the laws of astronomical and meteorological changes.
Twenty-four solar terms skillfully combine astronomy, agriculture, phenology and folk customs, resulting in a large number of related seasonal cultures, which have become an important part of China traditional culture. In the long farming society, the 24 solar terms have played an important guiding role in agricultural activities and have rich cultural connotations. Some important solar terms such as beginning of spring, Winter Solstice and Qingming also have interesting folk customs, such as "biting spring" and "hiking". ?
The 24 solar terms are still of practical value to our life and culture. For example, from the very popular Chinese medicine health care, autumn begins with the beginning of the autumn solar term, close to the great summer heat, hot and humid; Autumn ends in the first frost, close to the early winter, and the climate is dry and cold. Although early autumn and late autumn are in the same season, the climate is completely opposite, and the seasonal diseases encountered by doctors are completely different from those that Chinese medicine needs to prevent. Therefore, it is not enough to simply follow the four seasons, but also follow the solar terms.
