Ans:

"Three Volts" are the hottest days of the year. The word "volt" means that the yin is compelled by the yang to hide underground. The "three ambrosia" is the collective name for the first, middle and last ambrosia, which occurs annually from mid-July to mid-August on the solar calendar. According to China's lunar calendar (lunar calendar) climate laws, predecessors have stipulated: "the summer solstice after the start of the third g day for the first volts (the first volts), the fourth g day for the middle volts (two volts), the first g day after the fall for the end of the volts (three volts), each volts ten days **** thirty days." Some years "in the ambush" for twenty days, then *** have forty days.

According to the "General Book", "Yin Yang Calendar Book" and "almanac" check can be: this year is the solar calendar in 2005 AD, the lunar calendar B You (chicken) year. "Three Volts" is: July 15, the tenth lunar month gengzi day for the first volts (also known as the first volts); July 25 lunar twenty gengxu day for the middle of the volts (two volts); August 14, the tenth day of the seventh lunar month gengwu day for the end of the volts (three volts).

In general, the year, ten days per volt, three volts **** thirty days. But this year's "year" is "in the ambush" (two volts) twenty days. Therefore, the "three volts" period **** forty days. That is, from the beginning of the first ten of the lunar calendar, to the end of the last day of the ambush (lunar July 20) out of the ambush stop, before and after exactly forty days.

"Three days" is in accordance with China's ancient "stem and branch chronology" to determine. Every year after the summer solstice, the third g day (refers to the dry date with "g" word day) for the first volts, the fourth g day for the middle volts, the first g day after the fall for the end of the volts, together known as the three volts. As the saying goes, "hot in three volts", in accordance with China's traditional calendar, today began to enter the summer perennial relative hottest "three volts day". Three volts refers to the first, middle and last three consecutive periods. Generally speaking, the "three ambush days" in the "middle ambush" of the highest average temperature. Of course, the ancients of this projection method is not very scientific, not necessarily with the year's meteorological reality is closely integrated, around the year in the highest temperature extremes do not necessarily appear in the "middle of the ambush", and even not necessarily in the "three ambush". But in any case, the "three ambush days" is indeed the summer heat, we should pay attention to prevent heatstroke and cooling
