The traditional Chinese lunar calendar divides the year into 24 solar terms. Start of Winter, (Chinese: 立冬), the 19th solar term of the year.
Start of Winter is the first solar term of winter, which means winter is coming and crops harvested in autumn should be stored up.
In ancient times, the Chinese people took the Start of Winter to be the beginning of the winter. However, in fact, the Start of Winter is not the beginning of winter in terms of meteorology. The climate every year is different, so the beginning of winter could be quite different. And with the vast territory of China, winter of every area doesn’t begin at the same time.
