If 202 1 July 21begins to surrender, then the dog days are the initial surrender: July 21-July 30; Zhongfu: July 31-August 9; Terminal: August10-August 19. In this algorithm, the dog days last for 30 days.

If July 1, 202 1 1 is the first day of dive, then the initial dive time is July1/-July 20th; Mid-range: July 21-August10; Terminal: August10-August 19. In this algorithm, the dog days last for 40 days.

Mid-July to mid-August is the hottest time of the year. The lodging time in dog days is not fixed every year, and the length of lodging time is also different.

At present, there are two versions of the time of 202 1, one is 202 1 July, and the other is 202 11July. This is related to the algorithm of "three Geng days on the summer solstice", that is, the third Geng day comes from the summer solstice.

As the saying goes, "cold has three or nine, and heat has three volts." During the dog days, on the one hand, the ancients used cool drinks to escape the heat, on the other hand, they also held corresponding custom activities, such as "drinking to ward off evil spirits". Over time, a unique diet custom culture has been formed.

China has a vast territory, and different dynasties and regions have different customs. For example, in the Northern Song Dynasty, summer diet was a "green wallet" and "green lotus" was a lotus leaf, which had the function of clearing away heat.

In the dog days in Taizhou, Zhejiang, the elderly have the custom of eating chicken porridge, which is called "tonifying Yang". In a word, the origin of the custom of "Three Dog Foods" in China is related to the "Raf Festival" in the Han Dynasty, which was originally an activity to celebrate agriculture. This also reflects the richness and diversity of Chinese food custom culture from one side.
