Teachers' Day and Mid-Autumn Festival are one day in 2022.

In 2022, the Mid-Autumn Teacher's Day falls on one day, that is, September 2022 10, and the Mid-Autumn Festival falls on August 15 and 6 of the lunar calendar for three days. Because that day is also Teachers' Day, Teachers' Day also has three days off.

A "Happy Party" was staged on Mid-Autumn Festival and Teacher's Day. The calendar made according to the changing law of the sun is called the solar calendar, and the calendar made according to the changing law of the moon is called the lunar calendar. The calendar formed by the combination of the two is called the yin-yang calendar. The traditional lunar calendar in China belongs to the lunar calendar. The Mid-Autumn Festival falls on the 15th day of August in the lunar calendar.

According to the China lunar calendar, the big moon has 30 days, the small moon has 29 days, and the cumulative 12 months is 354 days or 355 days. In the Gregorian calendar, one revolution of the earth around the sun is the tropic year, with 365 days in a normal year and 366 days in a leap year. The difference between them is about 1 1 day.

In order to make up for the number of days different from the tropical year, so as to avoid the serious disconnection between the month and the season, the adjustment method is to arrange 13 months in some years, and there are two identical months, which are called "fixed leap", and the rules for fixed leap are based on 24 solar terms.

Due to the ingenious arrangement of lunar leap, the corresponding Gregorian calendar date of Mid-Autumn Festival every year is either about 1 1 day earlier than last year or next year, or about 19 days later than last year or next year. This also leads to a difference of one month between the earliest and latest Gregorian calendar dates corresponding to the Mid-Autumn Festival.

The statistical results of 200 years from 190 1 to 2 100 also confirm this point. The Gregorian calendar date corresponding to Mid-Autumn Festival is September 7th at the earliest (such as 2052) and June 8th at the latest (such as 19 19, 65438). Therefore, it is normal to celebrate the Mid-Autumn Festival every year from September 7th to June 8th, 10. Teacher's Day was established on 1985, and the date is fixed on September 10 of the Gregorian calendar every year. September 10, 2022 is the 38th Teachers' Day in China. Astronomical almanac shows that Mid-Autumn Festival and Teacher's Day are held only three times in the same year of this century, in 2022, 20041year and 2079 respectively.
