When is the calculation method of beginning of spring every year?

Beginning of spring, one of the 24 solar terms, is also called the Spring Festival, the First Month Festival, the New Year Festival and the New Year Festival. Standing means "start"; Spring represents warmth and growth. In ancient times, the method of "bucket handle Acupoint" used bucket handle and the Big Dipper in beginning of spring to point to Yin.

The current method of "fixing qi" divides solar terms, and beginning of spring is when the sun reaches longitude 3 15. In the era of cadres and branches, taking beginning of spring as the beginning of a year, beginning of spring means the beginning of a new cycle, the beginning of everything, and the meaning of all self-renewal.

Before Qin and Han Dynasties, the focus of etiquette and custom was not on January 1st of the lunar calendar, but on beginning of spring Day. Major festivals, such as offering sacrifices to ancestors, accepting blessings and praying for the New Year, exorcising evil spirits and avoiding disasters, welcoming the old and welcoming the new, welcoming the spring and celebrating agriculture, are held around the beginning of spring. This series of festivals not only constitutes the framework of the New Year's Eve Festival in later generations, but also retains its folk function to this day.

As one of the "twenty-four solar terms", beginning of spring, like Changsha, beginning of autumn and beginning of winter, reflects the changes of all seasons.
