When does the dog days of summer begin?

As the saying goes, "The calculation of the three hottest days of summer is closely related to the summer solstice."
There is no specific day for the beginning of the dog days. The beginning of the dog days is different every year and is determined according to the year. The third Geng day after the summer solstice belongs to the first dog days. Since the 365 days in a year (366 days in a leap year) are not an integer multiple of 10, a Geng day this year may not be a Geng day next year. That is, the date of Geng day is variable and not fixed, so there are slight differences in the date of the beginning of the dog days every year.
“The dog days begin on the third Geng day from the summer solstice”, which means that starting from the summer solstice, the dog days begin on the third Geng day. The "Geng day" here refers to the day with the prefix "Geng" in the ancient "Ganzhi calendar".
The "ganzhi calendar" was popular in ancient my country. The days were recorded in a cycle using 60 different names formed by matching 10 heavenly stems with 12 earthly branches. Any day containing the character Geng is called Geng Day.
2019 Summer Solstice Date: June 21, 2019
The first Geng Day after the summer solstice in 2019 is June 22, 2019 (Geng Yin Day)
The second Geng day after the summer solstice in 2019: July 2, 2019 (Gengzi Day)
The third Geng day after the summer solstice in 2019: July 12, 2019 (Gengxu Day)
Therefore, the first day of the "fu" period this year is July 12, 2019 (Gengxu Day) . Because the first dog days lasts for 10 days, this year's first dog days is from July 12th to July 21st.

Is the Lesser Heat solar term the first day of the dog days?

Neither Lesser Heat nor Greater Heat begins the day when the dog days begin. As the saying goes, "The heat is in the dog days." In my country, the dog days of summer usually occur after the third Geng day after the summer solstice, which is the so-called "the first dog days after the third Geng day after the summer solstice".
There are only 15 days between Lesser Heat and Summer Solstice, while the Dog Days usually occur 20 days after Summer Solstice. Therefore, the Dog Days have not yet arrived during Lesser Heat, but will begin about 5 days after Lesser Heat.
There are three hot days in a row, each of which lasts for ten days, and this is calculated according to the ten number of the heavenly stems. Therefore, the three dog days are divided into: the third Geng day after the summer solstice is the beginning day of the first dog day.
In ancient my country, the Lesser Heat was divided into three phases: "The first phase is the arrival of warm winds; the second phase is the crickets returning to their homes; the third phase is the eagles starting to prey."
The first sign is the arrival of warm winds: after the Lesser Heat day, there will no longer be a trace of cool breeze on the earth, but all winds will carry heat waves.
The second phase is that crickets live outdoors: Crickets live outdoors means that five days later, due to the hot weather, the crickets leave the fields and go to the corners of the courtyard walls to avoid the heat.
The third sign is the eagle's beginning of prey: The eagle's beginning of prey means that after five days, the eagle will move around in the cool high sky because the temperature on the ground is too high.
