How often do National Day and Mid-Autumn Festival fall on the same day?

National Day and Mid-Autumn Festival fall on the same day approximately once every 19 years, but this is not the case in some years. The main reason for this is the occurrence of a leap month.
The reasons why National Day and Mid-Autumn Festival fall on the same day are as follows:
The number of days in each month in the lunar calendar is established based on the moon's movement cycle. In fact, the average number of days in a month is 29.5306 days. If multiplied by 12, there are only 354.3672 days in a year. The earth's revolution around the sun in one cycle (tropical year, solar year) is 365.2422 days. Therefore, the actual number of days in a lunar year is 10.875 days less than that in a solar year, which is almost 11 days, and 209 days less in 19 years.
209 days divided by 30 is 6.9666, which means that in 19 years, the lunar year is almost 7 months shorter than the solar year. In order to make the difference between the lunar calendar and the solar calendar not too big, these 7 months must be added.
The Chinese lunar calendar is actually a typical lunisolar calendar - it is a combination of the lunar and solar calendars, and to make up for the seven months, people use the leap month method in the lunar calendar - seven leap months in nineteen years, that is, in the nineteen years of the lunar calendar, twelve are ordinary years, each with 12 months; plus seven leap years (the 3rd, fifth, eighth, 11th, 14th, 17th and 19th years respectively), and each leap year has 13 months.
In this way, the number of days in 19 solar years is almost equal to the number of days in 19 lunar years. Therefore, every time a birthday is 19 or a multiple of 19, there is a chance that the solar birthday and the lunar birthday will occur on the same day.

About the National Day military parade

There will be celebrations and military parades of varying scales every fifth and tenth anniversary. Historically, the seven most influential and representative military parades are the founding ceremony, the 5th anniversary, the 10th anniversary, the 35th anniversary, the 50th anniversary, the 60th anniversary and the 70th anniversary of the founding of the People's Republic of China.
Since the founding ceremony of the People's Republic of China in 1949, a total of fifteen National Day parades have been held.
A total of 11 National Day military parades were held in the ten years from 1949 to 1959.
In September 1960, the CPC Central Committee and the State Council implemented the policy of “practicing strict economy and building the country through diligence and thrift” and reformed the National Day ceremony system, implementing the policy of “a small celebration every five years, a big celebration every ten years, and a military parade on every big celebration” .
The military regulations issued by the Ministry of National Defense in 1964 listed the provisions for military parades for the first time. Subsequently, due to the "Cultural Revolution" and other reasons, there was no National Day military parade for 24 consecutive years.
In 1984, based on Deng Xiaoping’s proposal, the CPC Central Committee decided to resume military parades, and held a large-scale National Day military parade on the 35th anniversary of the National Day in 1984.
In 1999, the CPC Central Committee decided to hold a military parade to celebrate the 50th anniversary of the founding of the People's Republic of China, and a large-scale military parade was held in Tiananmen Square on October 1, 1999.
A grand military parade was held on National Day in 2009 to celebrate the 60th anniversary of the founding of New China.
The grand military parade held on National Day in 2019 to celebrate the 70th anniversary of the founding of the People's Republic of China was the first National Day military parade since socialism with Chinese characteristics entered a new era. It was also the first concentrated appearance of the People's Liberation Army after its reform and reshaping, and it strived to highlight the characteristics of the times.
