The calculation method of summer solstice dive is to calculate the head dive, which is the basis for establishing the first dive. What does "three Geng" mean? In ancient China, time was recorded by combining heavenly stems and earthly branches. The number of heavenly stems is 10, which is A, B, C, D, E, Ji, G, Xin, Ren and Gui, and the number of earthly branches is 12, which is Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You and Yi. Match the heavenly stems with the earthly branches, and you will get Jia Zi, Yi Chou, Bing Yin, Ding Mao ... and cross them 60 times, so it is called 60 flower Jia Zi. "'Three Gengzi' is to meet three' Gengzi' characters, and the fourth Gengri will be the first time. Because the number of heavenly stems is 10, there is a Geng Day every 10 day, such as Geng Zi Day, Geng Yin Day and Chen Geng Day. 365 days a year (366 days in leap year) is not an integer multiple of 10. One day this year is Geng Day, and next year is not necessarily Geng Day. Due to the uncertainty of Geng Day, the time of each year is different. How to calculate the dog days after entering? The dog days are divided into early, middle and late days, which are called dog days. The dog days are the hottest period of the year, because the nights are getting shorter and shorter, the days are getting longer and longer, and the sunshine is close to direct sunlight. But the summer solstice is not the hottest time, because at this time, a large part of the heat absorbed by the ground radiates at night. But it absorbs more heat and dissipates less heat every day, and it gets hotter every day. It will be the hottest in about 20 days to three volts. The date of the dog days is from summer to the third to the fourth Geng day, which is the first lodging, the fourth to the fifth Geng day is the middle lodging, and the second Geng day after the first Geng day to beginning of autumn is the last lodging. Every Geng day is 10 days apart, and the number of summer days is not fixed. Between the summer solstice and the beginning of autumn, there are four Geng days, the summer day is 65,438+00 days, there are six Geng days, and the summer day is 20 days. How is this calculated?
