On July 18th, there is a yellow calendar, and I will not calculate it specifically.

In 2012, the summer sunset date was July 18, and the first sunset was until July 27.

The number of days in the middle of the month is 10 days (because the beginning of autumn on June 20 of the lunar calendar belongs to the beginning of autumn before July), from July 28 to August 6;

The dog days begin on August 7 and end on August 16, with the dog days rising on August 17 and ending on the dog days.

On July 14 this year, the ambush began.

July 18 July 27 is the first ten days.

The summer solstice solar term in 2020 is June 21, and from this day, the date of the third Geng day is July 16, so this year's ambush time is this day.

Dog days are divided into the beginning, middle and last days, the first and last days are 10 days respectively, and the middle days are 10 days or 20 days. As mentioned earlier, the first day of the year begins on the third day after the summer solstice, and ends on the day before the fourth day after the summer solstice, and this year the beginning of the year begins on July 16 and ends on July 25.

This year, the beginning of the autumn solar term is August 7, and the first Geng day is August 15, so the end of the day is August 15, and the end of the dog day is August 24.

The reason why there are two situations of 10 days and 20 days in Zhongfu is because the time of the year is 365 days, but every 10 days there will be a Geng day, and 365 days will not be a multiple of 10, so the time of Geng day is not fixed. People conclude that if there are 4 Geng days between the summer solstice and the beginning of autumn, Zhongfu is 10 days, and if there are 5 Geng days, then Zhongfu has 20 days.

Cold in Sanjiu, hot in Sanfu, the number nine starts from the winter solstice, nine days and nineteen, it is easy to calculate on the Gregorian calendar, and the day of the number of volts is very difficult to calculate with the Gregorian calendar. Because according to the Chinese lunar calendar, starting from the summer solstice, the number of volts begins on the third Geng day of the lunar calendar, and at the same time, the first Geng day after the beginning of autumn is the beginning of the dog days. In this way, sometimes it is ten days, sometimes it is twenty days.

Generally speaking, it is about 45 days between the summer solstice and the beginning of autumn, and if there are four Geng days during this period, then the middle volley is ten days, and if there are five Geng days, then the middle volley is twenty days.

Year: Summer solstice, number of volts, start of mid-volt days, beginning of autumn, beginning of autumn, end of volcanic days: 2009 June 21, July 14, 20 days, August 7, August 13, 2010, June 21, July 19, 10 days, August 8, August 8, 2011, June 22, July 14, 20 days, August 8, August 13, 2012, June 21, July 18, 10 days, August 7, August 7, 2013, June 21, July 13, 20 days, August 7, 2014 June 21, July 18, 10 days, August 7, August 7.

"Dog days"It refers to the beginning, middle and last volts, which is about the period from mid-July to mid-August. After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are still longer than the nights, and the ground still absorbs more heat than it emits every day, and the temperature near the ground is getting higher day by day. to"Dog days"During this period, the ground absorbs almost less heat than it emits, and the weather is at its hottest.

After that, the ground begins to absorb less heat than the ground emits and the temperature slowly drops. So the hottest time of the year generally occurs on the summer solstice"Dog days"。

Counting from the third "Geng" day after the summer solstice, the first volt (10 days), the middle volt (10 20 days), and the last volcanic (counting from the first Geng day after the beginning of autumn, 10 days), is the hottest time of the year.

Hello, the time of incubation is different from year to year. July 18 will usher in the first day of this year's ambush, and then people will usher in the "dog days" of "high temperature, high humidity, and high heat". This year's "dog days" are 30 days, 10 days less than last year.

Hello, the time of incubation is different from year to year. July 18 will usher in the first day of the year.

Counting from the third "Geng" day after the summer solstice, the first volt (10 days), the middle volt (10 or 20 days), and the last volt (counting from the first Geng day after the beginning of autumn, 10 days), is the hottest time of the year.

It's different every year, but this year it was on July 18th.

Let's start from the third "Geng" day after the summer solstice!

July 18 is the first day;

On July 28, it was the middle of the ambush;

The time of ambush varies from year to year.

This year's ambush is on July 11.

According to the query of relevant information, in 2023, the time of the beginning and end of the first volt: July 11, 2023 to July 20, 2023, a total of 10 days, the start and end time of the middle volt: July 21, 2023 to August 9, 2023, a total of 20 days, the start and end of the end:

Liang Ying from August 10, 2023 to August 19, 2023, a total of 10 days.

The calculation method of dog days is calculated from the first Geng day after the summer solstice solar terms, dog days and three nine days are opposite, is the general name of the highest temperature period of the year, the establishment of dog days is also based on one of the twenty-four solar terms of the summer solstice festival as the establishment standard, the establishment date of dog days is not an accurate day of spring destruction, but the summer solstice of the year as a reference to establish.

The hottest cause

After the ambush, the surface humidity becomes larger, the heat absorbed every day is more, the heat emitted is less, and the heat of the surface layer accumulates, so it gets hotter and hotter day by day.

In addition, there is a lot of rain in summer, the air humidity is high, and the heat capacity of water is much greater than that of dry air, which is also an important reason for the hot and humid weather. In July and August, the subtropical high strengthened, and under the control of the subtropical high, the downdraft inside the high pressure made the weather clear and cloudless, which was conducive to sunlight exposure, and the ground radiation warmed, and the weather became hotter.
