In ancient times, which season did the Asian Year refer to?

In ancient times, the Asian year referred to winter. Especially the winter solstice in the 24 solar terms. Child years old, meaning second only to Chinese New Year.

During the Three Kingdoms period, Cao Zhi wrote "Ode to Winter Socks". Ceng Yun said, "Celebrate the New Year, celebrate it." The "pressing age" here is "sub-age".

The winter solstice is a very important solar term in the China lunar calendar. 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 0 and 23 in the solar calendar 65438+February 265438+February, which was the shortest day and the longest night in the northern hemisphere.
