What is the date of this year? How to live in dog days

When does the fall of 2019 begin? The annual fall time is not fixed, usually around the middle of July. As for the specific time, it depends on the summer solstice of that year. After the summer solstice, the third day is the fall time. Let's take a look at the date of the fall in 2019 through the relevant algorithms.

Time of arrival in 2019: July 12, 2019

The specific time of Sanfu is as follows:

Initial ambush time in 2019: July 12 - July 21, a total of 10 days;

The mid-term ambush time in 2019 is from July 22 to August 10, a total of 20 days;

The end of 2019: August 11 - August 20, a total of 10 days.

In addition to the 24 solar terms, there are other miscellaneous solar terms in China, such as' three volts, nine on the count, in and out ', which are used to express the weather changes. Like the 24 solar terms, they are closely related to people's daily life and agricultural production.

According to the provisions of the lunar calendar, the third 'Geng day' after the summer solstice (the first word in front of it is' Geng ') does not fall, the fourth' Geng day 'is mid fall, and the first' Geng day 'after the beginning of autumn is the last fall. Because the last fall is after the beginning of autumn, there is a saying in many parts of our country that "one fall after autumn".

From the beginning to the middle, the fixed time is 10 days for one volt. From the middle to the end, the preferred year is sometimes 10 days, some 20 days, with a difference of 20 days.

During the three volt period, the heat radiated from the sun to the ground is more than that radiated from the ground to the sky, and the atmospheric temperature continues to rise, so this is the hottest stage of the year. Usually in our city, the highest temperature in the dog days, most areas to reach 36 ℃ - 38 ℃ above, sometimes higher. The weather of several volts is closely related to agricultural production. Therefore, farmers attach great importance to agricultural activities at this stage. There are some agricultural proverbs, such as' radish in the first volt, vegetables in the second volt, buckwheat in the third volt with rain ','heat in the middle volt, rain in the second volt','No heat in the third volt, no knot in the innocent ','cotton in the first volt topping, forking in the second volt', and so on. In fact, these expressions are the long-term production practice of farmers It makes people pay attention to the seasonal changes, so as to achieve timely cultivation and harvest, in order to increase agricultural income and farmers' income.

How did the ancients live in dog days

Calm and cool

In the pre Qin period, people summed up a set of methods. In the Yellow Emperor's Canon of internal medicine, Su Wen, Si Qi Tiao Shen Da Lun, it said: "in March of summer, this is fan Xiu. When heaven and earth mingle with each other, all things are bright and solid. When you lie down at night and get up early, you are not tired of the sun. When you are determined not to be angry, you will make Huaying beautiful and your Qi will be released. If you love you outside, you will be able to grow up in the summer. Obviously, the core of this idea is to keep a happy mood in summer and not to get angry easily. The saying "Neijing" is also a great code of conduct for later generations to spend summer. Generally speaking, it means "calm and cool".

Qiu Chuji, a health expert of the Yuan Dynasty, said in his "theory on the news of taking care of one's life" that it is better to regulate one's breath and purify one's heart in summer. It is often like ice and snow in one's heart, and the heat is less in one's heart. We can't turn heat into heat, but regenerate it. To put it bluntly, we should adjust our mentality, cultivate our moral character, and make our heart calm and cool.

Good shade under big trees

It's easier said than done, but Liu Zongyuan, a writer of the Tang Dynasty, can't do it. When he was demoted to Yongzhou, Hunan Province, he couldn't sleep because it was so hot in the summer. In the middle of the night, he simply got up and went upstairs to have a cool. He once wrote the poem "climbing the West Tower in the bitter heat of the summer night": "I'm sorry that I didn't shoot my son, I'm more peaceful than an nengxi. 'it means that there is no hope for me to overcome the heat with peace of mind.

In order to adapt to the heat, the ancient folk first put forward the concept of 'cool'. 'cool', also known as' cool '. How to get cool? There are different choices in different times, but it is the most common method to block out the sun and avoid direct sunlight to reduce the body surface temperature.

For example, in the Tang Dynasty, people like to build a shed for summer. Although it was not invented in the Tang Dynasty, Changan people were more creative in using it for summer. Gao Lian of Ming dynasty recorded many anecdotes of the ancients in his book Si Shi You Shang Lu. The "summer shelter" refers to the cool phenomenon of the people in the capital at that time: "every summer, people in Chang'an used brocade as a shelter and set up seats as summer clubs. '

The summer party, a bit like the modern outdoor cool party, was still very popular in the Song Dynasty.

According to the book of dream in Tokyo written by song Mengyuan, Volume 8 is a miscellaneous sale in the streets of the moon. In the Northern Song Dynasty, people are the heaviest, and there is no season in June. There are often wind pavilions, waterside pavilions, precipitous buildings, snow sills, ice plates, floating melons, sinking plums, flowing cups, winding marshes, and new lotus flowers. You can sing in the distance and pass the night. But the summer club should be the ancient way for the rich to enjoy the cool. Most of the people used to build a simple shed under the tree, or go to the cave and other cool and low temperature places to spend the summer. As the saying goes, "it's good to enjoy the cool under a big tree" is the experience of the ancients in summer.

Enjoying lotus in summer

According to the article "June" in Volume IV of menglianglu written by Wu Zimu in the Southern Song Dynasty, people from Lin'an (now Hangzhou) had the custom of going to the West Lake on the sixth day of June to have a collective cool: "it's a boat painting in the lake, all of which are on the Bank of the lake to have a cool summer. '

The ancients used to enjoy the lotus in the summer. As Su Dongpo, a poet of the Song Dynasty, described in his "night in the West Lake", the "wild rice cattail" has boundless water, and the lotus blooms at night. '

In the Ming Dynasty, Suzhou was the most popular place for enjoying the lotus in the summer, surpassing Hangzhou. Suzhou people regard June 24 as the birthday of the lotus, which is the most spectacular day to enjoy the lotus by boat. According to the record of "Lotus Dang" in qingjialu, on the day of lotus's birthday, the painting boat Xiao Gu, went to the lotus Dang outside fengmenwai to enjoy the cool. '

There were many ways for the ancients to get water, such as' soaking 'was also a kind of cool custom: in the dog days, they had to take a cold bath in the river to get rid of the heat toxin of summer heat, so as to reduce the incidence of sores and fever. Ge Hong, the alchemist of the Eastern Jin Dynasty, is most famous for his "immersion" and his story is recorded in the article "going into the water for summer" in the book of four seasons: every time Ge Xianweng gets drunk, he gets hot in summer and goes deep into the bottom of the water. He comes out in eight days, so he can subdue his Qi.
