To be kicked

Today is the birthday of the great motherland, National Day on October 1. I wonder if you still remember when the National Day and the Mid Autumn Festival were the same day that we experienced? In fact, I don't remember very much myself. I read the record and found that it was 2001. After all, it was 13 years ago. It seems very far away, and it seems that it was in the last millennium.

The National Day falls on the same day as the Mid Autumn Festival. Many people think it is an excellent day. Yes, such a day is really rare. The Mid Autumn Festival meets the National Day. Therefore, many people choose to get married or open their business on this day. In 2001, my cousin got married on National Day.

However, I don't know whether you are clear about the next time when the Mid Autumn Festival hit the National Day in 2001? Grey Wolf comes to tell you that the next time will be in 2020. Six years later, October 1 will be the Mid Autumn Festival. You can take a look perpetual calendar I'll see.

Then what year will it be? I still searched and found that it was 2031, 19 years from 2001 to 2020, and 11 years from 2020 to 2031? Why?

What's next? I don't know myself. Anyway, I have to read them one by one. How painful it is to understand. If you are interested, please read them and tell me?

As for why there is a gap of 19 years and 11 years, it seems that there is no rule. It is also rumored on the Internet that every 19 years, it seems wrong. 2020+19=2039, the Mid Autumn Festival didn't hit the National Day.
