What does the vernal equinox mean? What is the special significance of the vernal equinox?

Introduction: The vernal equinox is the fourth solar term in spring and the fourth solar term among the 24 solar terms. This solar term belongs to spring and brings us the breath of spring. Everything revives, the grass grows and the warbler flies. So, what does the vernal equinox mean? What is the special significance of the vernal equinox? If you want to know, you can read my introduction.

"Equinox" has two meanings:

1, which means "vernal equinox and autumnal equinox, equally divided day and night".

On the vernal equinox, the sun shines directly at the equator, almost as long as the day and night in the world, that is, 12 hour. At this time, after half a year of darkness, the North Pole will first see the sun on this day, and the corresponding South Pole will also bid farewell to the sun on this day. After the vernal equinox, the position of the direct point of the sun will move northward, and the daytime time in the northern hemisphere will be longer and the nighttime time will be shorter. The difference is that the southern hemisphere will become shorter.

2, refers to the season equally divided.

If the period from the beginning of spring to the long summer is regarded as spring, the vernal equinox is the midpoint of spring, which just divides spring equally. It takes 90 days to travel from beginning of spring to Changchun, and the vernal equinox is divided into two, hence the name vernal equinox.

Special meaning of vernal equinox: Day and night are almost equal.

The vernal equinox is one of the solar terms reflecting the changes of the four seasons and the fourth of the 24 solar terms. In ancient China, beginning of spring, Changxia, beginning of autumn and beginning of winter were used to indicate the beginning of the four seasons. The vernal equinox, summer solstice, autumn equinox and winter solstice are in the middle of each season. On the vernal equinox, the sun shines directly on the equator, and the time between day and night is equal all over the earth. Therefore, the ancient vernal equinox and autumnal equinox are also called "equinox", and there is a folk proverb that "vernal equinox and autumnal equinox are equally divided day and night".

As the saying goes, "The spring equinox begins with wheat, and the fat and water should follow". A spring rain was warm. After the spring rain, I was busy plowing. The busy farming season in spring is about to begin, and spring management, spring ploughing and spring planting are about to enter a busy stage. After the vernal equinox, overwintering crops enter the growth period, so field management should be strengthened. As the temperature rises rapidly and the water demand is relatively large, farmers should strengthen water storage and moisture conservation.

Is the vernal equinox cold or warm: it's not cold anymore.

With the arrival of the vernal equinox, the weather is no longer cold, the shock has passed, and most areas have ushered in a bright spring. At this time, day and night are equal, but they can't completely relax, and there is still the possibility of cold spring.

During the vernal equinox, the daily average temperature in all parts of China rose steadily to above 0℃ except the alpine mountain area and the area north of 45 north latitude. At this time, the cold has passed and the temperature has risen rapidly, especially in North China and Huanghuai Plain. The daily average temperature rises to above 10℃ almost at the same time as the rainy areas along the Yangtze River and the south of the Yangtze River, entering a bright spring. On the vast land, on the bank of willow green, the grass grows in Fei Ying, the wheat is jointing, the rape blossoms are fragrant, the peach blossoms are red, the plum blossoms are yellow, and South China is a scene of late spring.

"The vernal equinox, Yin and Yang. So it's hot and cold day and night. " A word "fen" tells the boundary between day and night, cold and heat. According to the lunar calendar, "it refers to the vernal equinox, which is about Sunday. The northern and southern hemispheres are equally divided day and night, which is also half of spring, so it is called the vernal equinox."

In ancient times, the vernal equinox was also a traditional festival, which left many customs, such as laying eggs at the beginning of spring, eating spring vegetables, offering sacrifices to spring, laying eggs vertically and so on. One of the most bizarre is "laying eggs vertically".
