Introduction to the origin of the vernal equinox

Every year around March 20 in the Gregorian calendar, when the sun is at 0° of ecliptic longitude (the vernal equinox), it is the vernal equinox. On this day, the sun shines almost directly at the Earth's equator, and day and night are almost equal in length all over the world.

The vernal equinox was also called "the middle of the day", "the day and night equinox" and "the mid-spring moon" in ancient times. "History of the Ming Dynasty·Liyi" said: "The equinox is the point where yellow and red intersect. When the sun travels here, day and night equinox." Therefore, the meaning of the vernal equinox, firstly, refers to the equinox of day and night, each of which is 12 hours; secondly, it is the ancient equinox. Spring is from the beginning of spring to the beginning of summer, and the vernal equinox is within the three months of spring, dividing the spring equally.

In ancient China, the vernal equinox was divided into three periods: "The first period is when the primal bird arrives; the second period is when thunder makes its sound; and the third period is when lightning begins." That is to say, after the vernal equinox, swallows fly from the south, When it rains, there will be thunder and lightning in the sky. The record of the vernal equinox in the ancient Chinese calendar is: "Three days before the vernal equinox, the sun enters the equator."

How did the vernal equinox come about?

The vernal equinox is a festival and sacrificial celebration. Ancient emperors had the ritual system of worshiping the sun in spring and the moon in autumn. Zhou Rites: The Emperor of Heaven worships the sun at the sun altar. "Book of Rites": "Sacrifice the sun on the altar." Kong Yingda Shu: "It is also called the vernal equinox." Pan Rongbi of the Qing Dynasty wrote in "Records of the Years in the Imperial Capital": "Sacrificing the sun at the spring equinox and the moon at the autumnal equinox are the grand ceremonies of the country, and scholars and people are not allowed to worship.

In folk activities, it is generally regarded as the official start of outing. Activities include : When flying a kite, women and children write blessings on the kite in the hope that the gods will see it. Two hairpins are used to drink wine: both men and women, old and young, pick wild vegetables: Zhu Shuzhen's "Ten Poems on Spring Day": Writing and playing the piano are unintentional. I am not in the mood to pick out vegetables. As for food, there are spring vegetables, spring soup, spring wine, etc.

What are the three seasons of the vernal equinox?

The three seasons of the vernal equinox are said this. The bird arrives on the sun, the thunder sounds on the fifth day, and the lightning strikes on the fifth day. In other words, there is a period every five days. The vernal equinox is between March 20 and 21 in the solar calendar, so we add 5 to this time. The time of each of the three phases of the Spring Equinox can be calculated from the sky.

In the first phase, the Xuan (Yuan) bird arrives: Yan is coming

In the second phase, Lei Nai speaks: Thunder is the sound of Yang. Yang cannot come out of Yin, so it is excited and becomes thunder.

The third phase is the beginning of electricity: electricity is the light of Yang. If the Yang energy is weak, the light will not be seen. If Yang is strong, it will reach its peak. But it is suppressed by the clouds. The light is shining, so lightning begins. Detailed introduction to the Spring Equinox 2

The daily average temperature has risen above 10℃ almost at the same time as the rainy areas south of the Yangtze River, and the vast land has entered the bright spring. Willows are green on the shore, warblers are flying, grass is growing, wheat is jointing, rapeseed flowers are fragrant, peaches are red and plums are white, and spring is yellow. South China is a scene of late spring.

Around the spring equinox, the temperature will rise significantly, especially in the north. For example, the temperature will hover around 10 degrees, but there is an unexpected thing this year, that is, there is an El Ni?o phenomenon this year. The temperature this year will be 1 to 2 degrees higher than in previous years, and the temperature increase is particularly obvious in the Northeast. , so around the vernal equinox, the temperature is still relatively warm, but there are also sudden cold spells in spring.
