Mid-autumn festival. Details: Started in the early years of the Tang Dynasty, prevailed in the Song Dynasty, and by the Ming and Qing dynasties, it has become one of the major festivals in China along with New Year's Day.

Influenced by Chinese culture, the Mid-Autumn Festival is also a traditional festival in some countries in Southeast Asia and Northeast Asia, especially for overseas Chinese living there. Since 2008, the Mid-Autumn Festival has been listed as a national holiday.

Cultural customs: In ancient times, the Mid-Autumn Festival banquet customs of the Han nationality were the most elegant in the court. For example, the court of the Ming Dynasty sometimes ate crabs.

After the crab is steamed in a ploon, everyone sits around and tastes it, accompanied by wine vinegar. Drink Suye soup after eating and wash your hands with it. During the banquet table week, flowers, pomegranates and other seasonal fresh products are placed to perform the mythical opera of the Mid-Autumn Festival.

National. Detailed introduction: The word "National Day" originally referred to the celebration of the country, which was first seen in the Western Jin Dynasty.

Lu Ji, a writer in the Western Jin Dynasty, had a record of "the National Day is a good one, and the main worry is not harmful" in the article "On the Fifth Rank of Princes", and the major events of China's feudal era and national celebration are more important than the emperor's enthronement and birthday. Therefore, in ancient China, the emperor's enthronement and birth were called "National Day". Today the anniversary of the founding of the state is called the National Day.

Significance: The National Day is a characteristic of the modern nation-state, which appeared with the emergence of the modern nation-state and has become particularly important. It became the symbol of an independent state, reflecting the state and polity of the country.

Zhao Zhiheng, an astronomical education expert and director of the Tianjin Astronomical Society, explained that China currently uses both the Gregorian calendar (solar calendar) and the summer calendar (lunar calendar). In the Gregorian calendar, the Earth's revolution around the Sun is one return year, 365 days in a common year and 366 days in a leap year.

The lunar calendar is a lunisolar calendar that takes into account both the solar return year that is directly related to the sun and the synodic month, which changes in aspect with the moon. The average number of days for 1 synodic month is 354 days or 355 days for 12 synodic months, which is about 11 days different from the return year, and the cumulative amount of 3 years is more than 1 month.

In order to solve the contradiction between the two, the ancients adopted the method of "intercalation", that is, in some lunar years, there are 13 months and two of the same months.

The Year of the Rat is a leap year, with the addition of a "leap April". Due to the influence of "leap April", since then, the corresponding dates of the lunar festivals in the year of Gengzi Rat, such as the Mid-Autumn Festival, will be postponed by 18 days compared with last year

The corresponding solar calendar date for the Mid-Autumn Festival in the Year of the Pig is September 13, 2019Therefore, the solar calendar date corresponding to the Mid-Autumn Festival in the Year of the Rat naturally falls to October 1, 2020
