The Big Dipper moves from star to star ―― The passage of time

In some places in the pre-Qin period in China, the solar terms were determined according to the changes of the stars, and the Big Dipper rotated in a circular way, which was closely related to the 24 solar terms. Polaris is located at the northern end of the earth's axis, which is five times as long as the extension line connecting Tian Xuan and Shu Tian in the Big Dipper.

Because of the earth's rotation, Polaris is just on the axis of celestial rotation, so it is relatively static, while the Big Dipper on the axis seems to revolve around Polaris, resulting in a "star shift".

The alternation of seasons is closely related to the intersection of yellow and red. The intersection of yellow and red is the fundamental reason for the change of four seasons and the division of five zones, which affects the physical and geographical phenomena closely related to it. The 24 solar terms are related to the time spent on gossip and belong to the same system.

"Twenty-four solar terms" and "December Day" are the basic contents of the dry calendar, and the twenty-four solar terms are special festivals in the dry calendar to express the change of natural rhythm and establish "December Day" (month order). Because the 24 solar terms are determined by the rotation direction of Beidou bucket handle, this calendar is also called "ephemeris".
