The last day of winter is New Year's Eve. Is this correct?

New Year's Eve is the last day of the Lunar New Year in China, but it is not the last day of winter.

In the China lunar calendar, the beginning of spring solar term is usually considered as the beginning of spring. This day is usually around February 4 of the Gregorian calendar. In other words, according to the Gregorian calendar, the last day of winter is usually around February 3.

But New Year's Eve is different. New Year's Eve is the last day of the Lunar New Year in China, according to the traditional calendar of China. This day may be a day in the solar calendar 1 or a day in February, which has no corresponding relationship with the solar terms in beginning of spring.

So New Year's Eve is not the last day of winter. When is the last day of winter? It depends on which day is the solar term in beginning of spring.

It's a little winding. Do you understand?
