When is the Dragon Boat Festival over the years?

There are many traditional festivals in China. Sometimes my brain is short-circuited, and I can't remember which festival is the month and date. Actually, this is normal. Dragon Boat Festival, also called Zongzi Festival, is a traditional folk festival in China. Dragon boat racing and eating zongzi are two major customs of the Dragon Boat Festival. These two customs have been passed down in China since ancient times, and they are the first festivals in China to be selected into the world.

According to the timing method that the first month of the lunar calendar (that is, the first month of the lunar calendar) is the beginning of the summer calendar, and May is noon, so the fifth day is also called noon. Lei Han in Yu 'an period of Ming Dynasty quoted records in local chronicles: "The Dragon Boat Festival in midsummer begins, also known as the fifth day of May." This day is also called the heavy noon, also called Duanyang, which means that the yang is beginning to flourish, and it is also called Pujie. "The Origin of Things" quoted "The Chronicle of Jingchu": "On May 5, Duanyang, the cloud festival, the heavy noon." Heavy noon is also called Dragon Boat Festival. Jia Qinglu quoted the Chronicle of Jingchu as saying that May 1st was the capital, the 2nd was, the 3rd was, the 4th was, and the 5th was.
