When does the weather get longer in winter? What is the shortest day in a year?

1. The winter solstice is the shortest day and the longest night in a year. On the contrary, the summer solstice has the longest days. Every year after the winter solstice, the days get longer and longer, and it gets dark later and later until the summer solstice reaches the longest day. Modern science tells us that in winter solstice, the sun reaches the tropic of Capricorn, which is the longest day in the northern hemisphere. After this day, the sun began to return to the north.

China is located in the northern hemisphere, which is the shortest day and the longest night in a year. After the winter solstice, as the sun returns to the north, the days will get longer and longer until the summer solstice. The ancients observed this natural phenomenon and expressed it with a proverb, that is, "it is as long as summer solstice and as short as winter (solstice)"
