Is the winter solstice a new calendar or a lunar calendar? The new calendar is 65438+February 2 1-23 every year. But the winter solstice is a traditional solar term, so there is no such thing as a new calendar in the ancients. The winter solstice, also known as "the birth of the sun", is an important solar term in the China lunar calendar [1] and a traditional festival of the Chinese nation. The winter solstice is commonly known as "winter festival", "long festival" and "year-divided". As early as more than 2,500 years ago in the Spring and Autumn Period, China had observed the sun with earth gauges and determined the winter solstice, which was the earliest of the 24 solar terms, and the time was between June 65438+February 2 1 ~23 in the Gregorian calendar every year.

The ancients believed that since the winter solstice, the days have been getting longer and longer, the yang is rising, and the yang of heaven and earth is getting stronger and stronger, which represents the beginning of the next cycle. This is a good day.
