Are Lesser Heat and Greater Heat the hottest days of summer?

Answer: Of the Lesser Heat and Greater Heat, the Lesser Heat occurs before the beginning of the dog days, while the Greater Heat occurs in the middle of the dog days.
The dog days of summer refer to the period starting from the third Geng day after the summer solstice and ending 10 days after the first Geng day after the beginning of autumn, also known as the "dog days".
The dog days are between the Lesser Heat and the End of Heat. They are the hottest, most humid and stuffy days of the year. One dog day lasts ten days, which 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.
Starting from the third "Geng" day after the summer solstice, the first dog days lasts 10 days, the middle dog days lasts 10 or 20 days, and the last dog days lasts 10 days. 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.

How is the summer heat calculated?

The specific date of the summer heat is determined by the combination of the date of the solar term and the date of the Ganzhi calendar. According to my country's traditional calculation method, the third Geng day and the fourth Geng day after the summer solstice are the starting dates of the first and middle Fu periods respectively, and the first Geng day after the beginning of autumn is the first day of the last Fu period (summer Fu). Geng day is the day with the character "Geng" in the Ganzhi calendar, such as Gengzi, Gengyin and Gengchen.
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. As the saying goes, "A good fate is not as good as good luck." A person's destiny is already determined, and the only thing that can be controlled is his or her "luck."
