rare!Double -festival coincidence, only three times this century!

On the same day of the Mid -Autumn Festival as Teachers' Day, there are only three times this century

The Mid -Autumn Festival and Teacher's Day are coming. Coincidentally, the two sections appear on September 10th at the same time. Astronomical popular science experts said that these two festivals appeared on the same day, and this "coincidence" only three times this century, which is rare.

The Mid -Autumn Festival and Teacher's Day staged "Happy Meeting". Zhao Zhizheng, a member of the Chinese Astronomical Society and a director of the Tianjin Astronomical Society, explained that the calendar formulated by the rules of the sun is called the solar calendar, and the calendar formulated according to the law of the moon is called the lunar calendar. Combining the calendar formulated by these two is the yin -yang calendar. my country's traditional lunar calendar belongs to the yin -yang calendar. The Mid -Autumn Festival is on the 15th day of the lunar calendar every year, and it belongs to the festival of the lunar calendar.

The Chinese Lunar Calendar Law stipulates that 30 days in the big month, 29 days of the small month, and 12 Shuangwang Month for 354 days or 355 days; in the Gregorian calendar, the earth revolves around the sun for a week to return to the year, 365 days in a flat year, and 366 days in the leap year. The difference between the two is about 11 days.

In order to make up for the number of days that are different from the return of the return year, it does not cause serious disconnection of the month and season. The method of adjusting is to arrange 13 months in some years. The rules are based on the twenty -four solar terms.

"Because there are clever arrangements such as the gaze in our calendar, the Gregorian date corresponding to the Mid -Autumn Festival every year is either about 11 days earlier than the previous year or the next year, or about 19 days after the last year or the next year. This also leads to the birthday date corresponding to the Mid -Autumn Festival.

The statistical results from 1901 to 2100 also confirmed this. The birthday date corresponding to the Mid -Autumn Festival fell on September 7 (such as 2052), and the latest October 8th (such as 1919 and 1938 year). Therefore, every day from September 7th to October 8th each year is normal for the Mid -Autumn Festival.

Teacher's Day was only set up in 1985, and the date was fixed on September 10th of each Gregorian calendar. September 10, 2022 is the 38th Teacher's Day in my country. The astronomical calendar shows that in the 100th year of this century, the Mid -Autumn Festival and Teacher's Day were only three times on the same day, in 2022, 2041, and 2079.
