What is the first day of 2012? How was this determined?

2012 is July 18, the beginning of the day is divided into the beginning of the volcant, the middle of the volcanic and the last volt, according to the provisions from the summer solstice from the beginning of the 3rd day of the ambush for the ambush, and as the first day of the first volt, the 4th day of the beginning of the day as the beginning of the beginning of the day as the beginning of the beginning of the autumn day as the beginning of the first day, the second day of the day as the end of the volcant, that is, the end of the volcant. The "Geng day" mentioned here refers to the day with the prefix Geng in accordance with the Sexagenary Cycle Method. Therefore, both the first and last days are 10 days, and the middle is sometimes 10 days and sometimes 20 days.

When there are 4 Geng days from the summer solstice to the beginning of autumn, it is 10 days, and when there are 5 Geng days, it is 20 days. Beg.

The "dog days" are determined in accordance with the ancient "Ganzhi Chronicle Law" in China. Every year after the summer solstice, the third Geng day (referring to the day with the word "Geng" in the Ganzhi Chronicle) is the first volt, the fourth Geng day is the middle volt, and the first Geng day after the beginning of autumn is the last volt, which together is called the three volts. As the saying goes, "the heat is in the dogs".

The dog days refer to the three consecutive periods of the beginning, the middle and the end. The third Geng day after the summer solstice is the first day of the first volcane, the fourth Geng day is the first day of the middle volcan, and the first Geng day after the beginning of autumn is the first day of the last volcanic day, every 10 days, but in some years it is 20 days, such as 2005. Generally speaking, the average temperature of the "dog days" is the highest among the "dog days".

Of course, this calculation method of the ancients is somewhat different, and it is not necessarily closely integrated with the meteorological reality of the year, and the extreme maximum temperature in various places throughout the year does not necessarily appear in the "middle of the volt", or even in the "three dogs". But in any case, the "dog days" are indeed the time of the scorching heat in the middle of summer, and we should pay attention to heat prevention and cooling.
