What do winter solstice and summer solstice mean respectively?

The summer solstice is one of the 24 solar terms, which represents the coming hot summer. It has the longest day and the shortest night. The winter solstice is also one of the 24 solar terms, which means that winter is coming and the weather is very cold. The night is the longest and the day is the shortest.

The hot period is coming. By the summer solstice, summer is basically over half. At this time, the hot summer has arrived. Although the summer solstice is very hot, it is not the hottest time. After the summer solstice, the temperature will continue to rise. Everyone should take precautions.

Many people can't tell the meaning of these two solar terms clearly. In fact, they are easy to distinguish. One is in the hot June, and the other is in the cold June of 65438+February, just half a year apart, and the temperature is hot and cold.

The summer solstice is the earliest of the 24 solar terms. In the 7th century BC, the shadow of the sun was measured by civil soil gauges, from which the summer solstice was determined.

The Winter Solstice is a very important solar term, and it is also a traditional festival in China's lunar calendar. So far, there are still many places that have the custom of the Winter Solstice Festival. The winter solstice is commonly known as "Winter Festival", "Dragon Solstice Festival" and "Asian New Year Festival". As early as more than 2,500 years ago in the Spring and Autumn Period, China has used the earth to observe the sun to determine the winter solstice, which is the earliest of the 24 solar terms.

The time is between February 22nd and 23rd of Gregorian calendar 12. The winter solstice is the shortest day and the longest night in the northern hemisphere all year round. After the solstice in winter, the days will get longer day by day. The ancients said about the winter solstice: When the cathode came, the yang began to grow, the sun went south, the day was short and the shadow was long, so it was called the "winter solstice".

After the winter solstice, the climate around the country entered the coldest stage, which is often called "entering the ninth". In China, there is a folk saying that "it's cold in March, and it's dog days". Now, some places still celebrate the winter solstice as a festival.

The northern region has the custom of slaughtering sheep and eating jiaozi and wonton on the winter solstice, while the southern region has the custom of eating glutinous rice balls and long noodles on the winter solstice. There is also the custom of offering sacrifices to heaven and ancestors on the winter solstice in various regions.

There is no specific custom when the summer solstice comes, but some people will cook some mung bean soup on this day to relieve the heat, which is the most important weapon to relieve the heat in hot summer. But the winter solstice is different. It has traditional food to commemorate, that is, jiaozi.

On this day, every family in the north will eat a hot jiaozi, and the south will eat a bowl of sweet glutinous rice balls to show family reunion.

Summer Solstice and Winter Solstice are the two most extreme solar terms among the 24 solar terms, but these two solar terms must be distinguished from Changxia and beginning of winter because their meanings are quite different.
