Detailed explanation of the twelve earthly branches: a formula for quickly calculating the annual and daily branches

First, calculate the formula of annual trunk and branches.

From the palm of your hand, you can count the annual stems and branches, and the flowers in Zhi Zi begin.

Yangzhi began on the 10th and lasted for four years.

Every other position is reversed for ten years, and the end of the year is 503.

Sixty numbers are added and subtracted one by one, and thousands of years are counted in the palm of your hand.

Calculation method: "Palm counts one year of dry branches and Zhi Zi flower roots." This method is to arrange the branches on the palm of your hand and calculate the annual branches on the palm of your hand. First locate the ground branch on the palm of your hand (Figure 1), and then start with the ground branch position as Jiazi, which can be set to 1864, 1924, or 1984, all of which are Jiazi years. "Yangzhi is the beginning of ten days, and Tiangan is the end of four years." Zi, Yin, Chen, Wu, Shen and Xu in the earthly branches are all Yang branches, and they are also the beginning of every ten days. Everything is A, that is, Jia Zi, Jia Xu, Shen Jia, Wu Jia, Chen Jia and Jia Yin. The mantissa of the Gregorian calendar in these years is 4. "Every other place for ten years, 503 at the end of the year." There are ten days to dry twelve earthly branches, heavenly stems and earthly branches combination. Every time the heavenly stems circulate, the earth branch is always with the next two branches (Xun Kong).

The first branch left is the beginning of the later period. We started from the sub-position of the earthly branch, and pushed back every other one, that is, from the sub-position to the 10th anniversary of JOE, and then from the 10th anniversary of JOE to Shenwei Jiaxu, with a mantissa of four every year and an interval of ten years. After the beginning of the tenth day is determined, the mantissa of the year is 4 as the starting point, and the mantissa of the calendar year is 5, 6, 8, 9, 0, 1, 2, 3 from the next branch, and then it is the beginning of the later period. According to this method, if the year of Jiazi is set to 1984, we can know that 1994 is JOE, 2004 is Shen Jia, and 20 14 is Wu Jia. After determining the number of Gregorian calendar years starting every ten days, we can push forward the trunk and branches of any year as needed. Although it is meaningful, it can push the trunks and branches of thousands of years forward.

Second, the formula for calculating months and hours.

Do it the day before the fifth day, and the first to fifth day of the month is the order.

The number of dry days per year matches the monthly appearance, and the number of people per day is the same.

Throughout the ages, from the beginning of a year to the beginning of a day, it can be divided into five situations according to the method of combining day with work, that is, both parties set the month (time) in a year (day) in the same way. We also use this method. The previous day is the main method, that is, A and B are the main methods, and B and G are the main methods. The ordinal number A is 1, B is 2, C is 3, D is 4, and E is 5, which becomes a fixed ordinal number for calculating the month and time. "The annual stem is separated from silver moon", and the monthly stem of a certain year is calculated. First, look at the combination of annual stem and trunk branch, then find out the ordinal number of trunk branch according to the method of "before the combination of five heavenly stems", set this trunk branch to zero, and determine the heavenly stems in silver moon according to the ordinal number. For example, 1998 is Wuyin, the reform movement of 1898, and the reform movement of 1898 is the same as the reform movement of 1898, which belongs to the same silver moon method.

The ordinal number of five ends with five, starting from five, and after five days of self, Geng, Xin, man and ghost, it can be calculated that 1998 silver moon's heavenly stems are A, and other months' heavenly stems are easy to calculate. The calculation method of this sentence is basically the same as that of silver moon's annual dry combination, except that after the daily dry combination is determined, the dry combination is calculated from the last dry combination itself and checked by ordinal number, which is the dry combination of the day. Such as auspicious day, auspicious day and Jiazi are the same type, with Jiazi as the main type, and Jiazi's ordinal number is "1". When matched with itself, Tiangan on that day is Jiazi. Similarly, the heavenly stems in bedsore are mainly five because of the combination of five and bedsore, and the ordinal number is five, from five to non-healing, and bedsore is non-healing.
