Why don't I use a perpetual calendar when I arrange the constellations?

As many customers know, Mr. Yan doesn't need a calendar, books or software, just a piece of paper and a pen. Some people may ask: Teacher Yan, do you still remember living in heavenly stems and earthly branches every day? I didn't write it down. But Miss Yan has an idea. Generally speaking, it is not difficult to arrange the stem and branch of the annual column, the moon column and the time column, so it can be calculated according to the formula. The difficulty lies in how to know heavenly stems and earthly branches every day. Teachers in blind schools can arrange eight characters without looking up the perpetual calendar. They remember the branches and branches on the first day of the first month of each year, use divination of Yin and Yang to indicate the size of twelve months of the year, or directly indicate which months the big month is, and then make up a formula. In this way, the daily heavenly stems and earthly branches of that year can be calculated. For example, in a certain year, the first day of the first month is Bingzi, the first month is big, the first day of February is Bingwu, and the ninth day of February is Mao Yi. According to the order of sixty flowers, you can also use a perpetual calendar. Some people call this calculation method "meteor chasing the moon", and its formula has several modes, all of which are arranged by the discerning person for the blind in advance. These recipes are secret and only passed on to the blind master. Therefore, some people say, "Unless you are blind, don't pass by the meteor to catch up." At present, these secrets have been uncovered. It's unfair to the blind! The formula of the blind master has one sentence and a dozen words every year. Many experts can recite from 1922 to 20 12. But I don't recite these words at all, and Teacher Yan's formula is less than thirty words. Hehe, when Mr. Yan was studying, his grades in Chinese and mathematics were always outstanding, especially in mathematics, and even the entrance exam was full marks (I have always been proud of it). A few years ago, Teacher Yan spent three nights compiling this formula. On the first night, I calculated the calculation method over and over again, and then I chose the simplest method to make up the formula, which consisted of eight sentences and 56 words. The method and formula were verified the next night, and no mistakes were found. On the third night, fifty-six words were shortened to twenty words. The formula is simple and practical, and sometimes heavenly stems and earthly branches can be calculated in three or four steps. As long as the calculation is correct, it is absolutely accurate! This is the simplest formula I know so far! 44 times 5 yen 5, plus 2 yen 3 1. 267 13 Yan 1, 829 ten Yan Yu 4. Yan's verbal decision also represents a word. Only I can understand the formula at present. In fact, it is the fastest to arrange eight characters through software, and it is of little significance to know this tactic. Teacher Yan doesn't want to fully disclose this tactic. So please don't ask Miss Yan this formula! It is not difficult to arrange the annual column, the moon column, the time column and the Universiade, and there are not many contents or rules to remember. If you don't want to recite the formulas of "five tigers catching" and "five mice catching" when sorting out the moon column and the time column, Teacher Yan can tell you a simple formula: multiply two and subtract one. How to use it? First, arrange the annual dry and the daily dry in order: A 1, B 2, C 3, D 4, E 5, G 6, G 7, Xin 8, ren 9, G 10. When arranging the moon column and the time column, the sky is mainly arranged. The sky dryness of the moon column is calculated by the sky dryness of the year column and the sky dryness of the hour column is calculated by the sky dryness of the sun column. In fact, one formula is enough for both. If you want the moon column to be dry, multiply the annual drying number by 2 and then subtract 1. If it exceeds ten, take a single digit, and the number obtained matches the dry month and then push it to the required month. Let's give an example: ask for the moon's dryness in the third afternoon. C is 3, multiplied by 2 equals 6, and subtracted from 1 equals 5. 5 is e, then the next month begins with e, and the next month is bingshen. Therefore, it was Shen Bing who applied to enjoy the moon in the afternoon. You can push it on your palm when you count. The so-called "pinch your fingers and calculate." The time column method is the same as the moon column method. It should be noted that: according to the current practice of building yin in the first month, we should pay attention to the elements and whether the ugly month belongs to the previous year or the next year when calculating the ugly month.
