I want to know when 1975 is beginning of spring.

Beginning of spring, February 4th 1975, Tuesday, 24th of the twelfth lunar month.

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. Due to the vast territory of China, the climate varies greatly from place to place. The specific climatic significance of "Li" does not apply to all parts of the country, and the corresponding area is only South China, with the dividing line from Guilin, Guangxi to Ganzhou, Jiangxi.

Beginning of spring time (when the daily average temperature reaches 10 degrees Celsius for five consecutive days, it is regarded as spring), and the area south of the line has the breath of spring; However, 93% of China's land area is still in winter, and when it comes to Heilongjiang, it is often in the long summer, and spring comes in Grain Rain. "Li" is just a reference in many areas.
