Sanfu is the hottest 30 or 40 days of the year in Central China. Sanfu is calculated according to the lunar calendar, which is between the late July and the early August of the lunar calendar. The time of ambush is not fixed every year, and the length of the ambush is not the same. It needs to be calculated by checking the almanac. It can simply use the four word formula 'summer solstice three Geng' to express the date of ambush, that is, from the third 'Geng' day after the summer solstice, the first ambush is 10 days, the middle ambush is 10 days or 20 days, and the last ambush is 10 days.

In ancient China, the 'ganzhiji Japanese method' was popular. 60 groups of names, which were matched by 10 heavenly stems and 12 earthly branches, were used to record the dates and circulate them. Every day when there is the word "Geng", it is called "Geng day". The word "Geng" of Geng day is the seventh of the ten Heavenly Stems of "a, B, C, D, e, I, G, Xin, Ren, GUI". Geng day is repeated every 10 days.

From the beginning of the summer solstice, according to the arrangement of the days of the GaN and Zhi dynasties, the third day of Geng is the first day of ambush, the fourth day of Geng is the middle day of ambush, and the first day of Geng after the beginning of autumn is the last day of ambush. When there are 4 g days between the summer solstice and the beginning of autumn, the median period is 10 days, and 5 g days is 20 days. It seems that the occurrence of the day of Geng will affect the length of the middle volt, so there are some years with 30 days of dog days and some years with 40 days of dog days.
