The following are the key points.

Second, the specific calculation

Type 1:

For example, when is the ugly day in June of 54 1, and the most important thing is how to calculate it?

Step 1: First of all, 54 1 year is the seventh year of Liang Wudi Xiaogan Datong. This step can be found in most dictionaries and is easy on the Internet.

Principle of the second step: after finding the first grade, it is easy to count the number of days to search and the number of days in the first grade.

Step 2: Download Mr. Chen Yuan's "Twenty Historical Leaps Table" and find on page 76 that June of that year is the theory of Xin Chou, that is, the first day of the 54th1lunar calendar is July 9th in the western calendar.

According to the list of cadres and branches, the first day was Xin Chou, followed by Xin Chou, Ren Yin, Gui Mao, Chen Jia, Yi Si, Wu Bing, Ding Wei, Wu Shen, Ji You, Geng Xu, Xinhai, Ren Zi and Gui Chou. So that day is June 13th of the lunar calendar (54 1) and July 20th of the solar calendar (54 1).

Ps: The above difficulties mainly lie in looking up the 20th Century Shuo Leap Table. The first row in the horizontal row of the table frame is the year, which is subject to the year number. The rightmost line in the vertical line is the month. The intersection point is the main branch corresponding to the first day of the month, and there are vertical small characters on the left side of the main branch, representing the first day of the Gregorian calendar.

This book is available on verycd.

Type 2 (the known date is the date of the branch)

Quickly check the dates of trunks and branches: The formula for calculating the dates of trunks and branches according to the known dates is:

g = 4C+[C/4]+5y+[y/4]+[3 *(M+ 1)/5]+d-3

z = 8C+[C/4]+5y+[y/4]+[3 *(M+ 1)/5]+d+7+I

Where c is the number of centuries minus one, y is the last two digits of the year, m is the month and d is the number of days. 65438+ 10 and February are calculated according to 65438+March and 65438+April of the previous year. Odd months i=0 and even months i=6. The remainder of g divided by 10 is heavenly stems, and the remainder of z divided by 12 is earthly branches.

When calculating, the number with [] indicates rounding.
