Is beginning of spring a lunar calendar or a solar calendar?

Beginning of spring belongs to the lunar calendar.

Beginning of spring is the first of the twenty-four solar terms, and it was included in the first month solar terms in the official yearbook of Ming and Qing Dynasties. The arrival time is on February 3-5 of the Gregorian calendar every year (around the first day of the first lunar month), when the sun reaches 3 15.

Beginning of spring marks the end of the winter when everything is hidden and begins to enter the warm and sunny spring. In nature, the most striking feature of beginning of spring is that everything is beginning to show signs of recovery. As far as beginning of spring is concerned, you can obviously feel the breath of early spring in the Tropic of Cancer (Huangchi Jiao Jiao) and its south. Due to China's vast territory, large span between north and south, and different natural rhythms, the "beginning of spring" in many areas is only a prelude to spring, and everything has not yet recovered, and it is still in the winter when everything is hidden.

The significance of the twenty-four solar terms

Twenty-four solar terms are special festivals in the calendar to express natural rhythm changes and establish "December construction". A year is divided into four seasons, three months in spring, summer, autumn and winter, and two solar terms in each month. Each solar term has its own unique meaning. Twenty-four solar terms accurately reflect the change of natural rhythm and play an extremely important role in people's daily life. It is not only a seasonal system that guides agricultural production, but also a folk system that contains rich folk customs.
