Why am I so sad when it comes to Chinese New Year?

Because it is a phobia of going to work, every wasted day is closer to work.

Development and evolution:

The establishment of the ancient branch calendar provides a prerequisite for festivals, and primitive beliefs and sacrificial culture are important factors in the formation of festivals.

The first year of the ancient folk refers to the "beginning of spring" in the twenty-four solar terms of the Ganzhi calendar. When "bucket handle refers to the Yin" on that day, it is the node of beginning of spring, that is, the longitude of the sun reaches 3 15.

Beginning of spring is a node in the calculation of the ecliptic, which is the law of astronomical phenomena. "Spring" was highly valued by people in ancient times. If there is a "double spring" year, it is regarded as a bumper year. At the beginning of the Spring Festival (beginning of spring), everything is renewed, which means a new year and a new cycle begins.

In the historical development and evolution, due to the changes of dynasties and calendars, the date of the New Year has also changed, and the dates of the New Year in previous dynasties are not consistent.
