Query on the trunk and branch of Huangli

When it comes to heavenly stems and earthly branches's calendar comparison table, as we all know, some people ask about heavenly stems and earthly branches's calendar, while others want to ask how heavenly stems and earthly branches calculates the year. Do you know what this is about? In fact, the age of the branch is converted. Let's take a look at the query of the perpetual calendar, hoping to help everyone!

Heavenly stems and earthly branches calendar comparison table

1, cross-reference table of trunk and branch calendars: query year of trunk and branch calendars is Wednesday May 13, April 16 of the lunar calendar, Ding Maonian, Yi Siyan, Ren Xunian, cross-reference table of trunk and branch calendars.

2. heavenly stems and earthly branches calendar comparison table: How to calculate the year with heavenly stems and earthly branches and heavenly stems and earthly branches is a complicated problem. According to the historical sequence, A.D. 1 corresponds to No.1, and A.D. 2 corresponds to No.2 in Shu Ren. So, what about BC? In fact, the era of BC is the era of AD, but there is no AD 0. Then, it is natural to write BC 1 as "a 1", which can be illustrated by enumerating a special number axis (Figure 1). Next, I want to use a very important mathematical concept, the concept of residual classes. Heavenly stems and earthly branches in 2006.

Let's look at an example: take the number 12 of a clock as one, then other points, such as 13: 00, indicate that the pointer points to 1, and 15: 00 indicates that the pointer points to 3. 13 divided by 12 and 1, 15 divided by 12 and 3 cannot be divisible by 12, so the remainder is themselves. In this way, 1,13,3, 15 can be divided into a group according to the types of residues, and 12 "residue classes" can be divided into 12 L, 2,3, …1in total. Inspired by the conclusion of the whole hour, starting from the concept of residual class, we can deduce that by dividing the AD year by 60, we can classify these 60 different numbers and get 60, that is, the number of AD years corresponding to 60 different years. Since the year of 1 is set to 1, we can directly divide the year of AD by 60. What is the remainder? The corresponding number is the required year. For the year of BC, because the calculated remainder is a negative integer between -60 and-1, and because there is no year 0, the negative integer remainder will eventually be converted into a number within 60 by adding 6 1. For example, A.D. 12, that is, Ren ShenNo. 12, the year when A.D. 60 is divided by 12 is naturally the year of Ren Shen, and the year when A.D. 60 is divided by 35 is also the year of B. Then the traditional method is used to test, and the result is completely correct. In addition, the number of numbers is consistent with the size of the remainder, which saves the time of looking up the table and makes my method fast and accurate. We might as well take a few numbers at will. In A.D., if you divide by 60 or more and 55, it will be number 55. In B.C., it will be-divided by 60, and the rest will be -25. The number within 60 will be number 36, which is Shen Bing. The year of AD, divided by more than 60 18, is the year of Wuyin, the year of BC, -60, and the remaining years within -4L and 60 are the years of Chen Geng. I checked, and everything is correct. Only the operation in BC is a little more complicated, but it is still simpler than the traditional method. 3. Establish a mathematical model-know the year of the main branch and find out the year of the AD, because the year of the main branch is actually only 60 years, but the year of the AD is infinite. So we can draw an image of such a function (Figure 2): 1992 heavenly stems and earthly branches cross-reference table.

As can be seen from the figure 1, a y (branch) corresponds to an infinite number of x (a.d.), and the relationship between x and y can be obtained from the image:

For example, the number 1 is a year, which can be 1, 6 1, year, year ... 60 BC, the year before last, the year before last ... As for which year, it is up to historians to calculate. After all, the 60-year interval is still sure to be verified, but if it is the third, the application example is 1. As we all know, the year of the main branch is AD. Gong Zizhen, a patriotic poet of the Qing Dynasty in China, wrote a poem "Poetry of the Sea" ("Don't stick to one pattern"), but when was the year of the sea? I have consulted Selected Works of China in Past Dynasties (Education Press) and Concise Literature Manual (Press), and only saw Gong Zizhen's year of birth and death (-) Poems in Past Dynasties, but that's enough. According to the year of birth and death (), after dividing by 60, the remaining 5 1 is the No.5 1 of Xinhai, and because the poet's life is only 50 years, he will only meet once (No.39), which is 48 (60-5L+39 = 48) different from 51. 2. As we all know, in the modern history of our country, there are a series of unequal treaties named after the year of dry support, such as the Reform Movement of 1898, the treaty of shame and ugliness, and the Xinhai. Because the words that make up the year of cadres and branches are uncommon and easy to forget. If you don't have a chronology of events at hand, just remember the year. Divided by 60 in the year of 1898, the remaining 38, that is, the year of 1898, is the same.

Heavenly stems and earthly branches converted age to calculate the annual remainder of 4 1, which should correspond to ugliness.

Year, the annual remainder is 5 1, corresponding to 19 1 1 year. 1 conclusion and significance of the paper. This paper is an attempt to study the historical age by mathematical method. I think these calculations can tell people that we can explore a wider field with mathematical tools. 2. The method deduced in this paper is relatively simple, and anyone with a little knowledge of mathematics can use it. It can be better used for the conversion of heavenly stems and earthly branches chronology and AD chronology, and it is much faster than the traditional method. 3. The chronology conversion method derived in this paper can help foreign friends better understand the ancient history and culture of China and contribute to the spread of Chinese civilization all over the world.

The above is about the query of the perpetual calendar, and it is about sharing the query of the perpetual calendar. I read the comparison table of heavenly stems and earthly branches almanac, hoping to help everyone!
