When is the Mid-Autumn Festival? Wu wrote "Dream" in the Southern Song Dynasty, saying: "The Mid-Autumn Festival on August 15 is exactly half of it. It is called the Mid-Autumn Festival, and the moonlight is bright." Scientifically, Mid-Autumn Festival can be defined in two ways: in astronomy, autumn is from the autumnal equinox to the winter solstice. Therefore, the Mid-Autumn Festival should be held in beginning of winter, that is, on the 5th or 6th of October on the Gregorian calendar165438+/kloc-0. Meteorology takes September, 65438+ 10, 165438+ 10 in the solar calendar as autumn, so the Mid-Autumn Festival should be around 65438+ 10/6 in the solar calendar. These two date systems are far from August and half moon of the lunar calendar. In western astronomy, the four seasons of spring, summer, autumn and winter customarily start from vernal equinox, summer solstice, autumnal equinox and winter solstice, which is really unreasonable. It is not as logical as China's astronomical example, and it started from beginning of spring, Changchun, beginning of autumn and beginning of winter. If China's astronomical method is used to divide the four seasons, the Mid-Autumn Festival should be at the autumnal equinox, not far from the eighth half of the lunar calendar. The autumnal equinox is September 23rd in the solar calendar. Last year the Mid-Autumn Festival was six days after the autumnal equinox, and this year it is six days before the autumnal equinox. Next, I will talk about places where I can miss the moon around the autumnal equinox, so I advocate keeping the Mid-Autumn Festival.
Why is the Mid-Autumn Moon particularly concerned? According to the above, the moon in Mid-Autumn Festival is neither particularly bright nor particularly round, and it doesn't shine for a long time. Then why has it been worshipped by our country for more than a thousand years? It is not only people in China who miss the Mid-Autumn Festival. Even in western Renye Fang, the Mid-Autumn Festival is very important, and it is called the Harvest Moon for a reason. An article in the Mid-Autumn Festival Park last year said that the Mid-Autumn Festival moon came out late, which was false. This inevitably makes the Mid-Autumn Moon aristocratic. In fact, the moon in the Mid-Autumn Festival is the poorest, and you can enjoy it regardless of your position. The Mid-Autumn Moon is not characterized by coming out late, on the contrary, it comes out early because of the moon after the Mid-Autumn Festival.
