When is the spring breeze?

Spring breeze refers not to time, but to the vernal equinox, that is, March 19 or 20 or 2 1 or 22 every year. The vernal equinox usually refers to the moment when the sun's ecliptic is at 0, which is around February 15 of the lunar calendar every year (about March 20 to 2 1 in the Gregorian calendar).

The vernal equinox is the midpoint of 90 days in spring. One of the 24 solar terms, around March 20 of the Gregorian calendar every year, when the sun is located at 0 (vernal equinox) of the yellow meridian. On the vernal equinox, the sun shines directly at the equator of the earth, and the seasons in the northern and southern hemispheres are opposite. The northern hemisphere is the vernal equinox and the southern hemisphere is the autumnal equinox. The vernal equinox is a new year in Iran, Turkey, Afghanistan, Uzbekistan and other countries, with a history of 3,000 years.

The vernal equinox was also called "Japan-China", "Day and Night Equinox" and "Midspring Moon" in ancient times. "Li Mingshi Yi" said: "The dividing line, the turn of Huang Chi, the sun stops here, and the day and night are equally divided." Therefore, the significance of the vernal equinox, first, refers to the equal division of day and night, each of which is 12 hours; Second, in ancient times, it was spring from beginning of spring to long summer, and the vernal equinox happened to be in the three months of spring, and spring was equally divided.

Spring, also known as spring, is the first of the four seasons, which refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. This is the season when everything comes back to life. The Gregorian calendar in the northern hemisphere is March-May, and in the southern hemisphere (such as Australia) it is September-165438+ 10. In meteorology, the beginning of spring is that the average temperature is above 10℃ for five consecutive days. In spring, the climate is warm and mild, and there is rain in most inland areas of China, where everything germinates and the climate is changeable.
