The traditional Chinese solar calendar divides the year into 24 solar terms. Major Cold (Chinese: 大寒), the 24th solar term, begins this year on Jan 20 and ends on Feb 3.

Major Cold is the last solar term in winter and also the last solar term in the annual lunar calendar. In this period, snow, rain and icy cold weather exert a big influence on people's lives.

During Major Cold, as the cold current moves southward, the weather is very cold.
