Definition of words:

Solar terms can be understood in two ways:

One of the 24 solar terms. Since the slight cold, every additional 15 Yang meridian is another solar term. There are 24 solar terms: slight cold, beginning of spring, fright, Qingming, long summer, mangzhong, xiaoshu, beginning of autumn, Bailu, cold dew, beginning of winter and heavy snow. Called the twelve solar terms.

Second, the floorboard of the twenty-four solar terms. Solar terms are generally calculated according to the lunar calendar.

The earth revolves around the sun at 5: 48: 46 every 365 days and rotates once every 24 hours. Because the orbital plane of the earth's rotation is not the same as the equatorial plane, but maintains a certain inclination angle, the position of direct sunlight on the earth is different all year round. In the northern hemisphere, when the sun shines directly at 23.5 degrees north latitude, it is called the summer solstice in astronomy; When the sun shines directly at 23.5 degrees south latitude, it is called the winter solstice; The solstice in summer and the solstice in winter mean that it is now halfway between summer and winter. When the sun shines directly on the equator twice a year, it is the vernal equinox and the autumnal equinox, which is in the middle of spring and autumn. The day is as long as the night. The solar terms reflecting the changes of the four seasons are: beginning of spring, vernal equinox, long summer, summer solstice, beginning of autumn, autumn equinox, beginning of winter and winter solstice. Among them, beginning of spring, Changxia, beginning of autumn and beginning of winter are collectively called "Sili", which means the beginning of the four seasons. There are five solar terms reflecting temperature changes: slight summer, great summer, great summer, slight cold and great cold. There are seven solar terms reflecting weather phenomena: rain, Grain Rain, white dew, cold dew, first frost, light snow and heavy snow. There are four solar terms reflecting phenological phenomena: Jing Zhe, Qing Ming, Xiaoman and Mang Zi.
