坎【六】、震【七】、離【八】、兊【九】。已上四卦者，四正卦，為四象。毎歳十二月，每月五月，【按：「月」字當作「卦」。】卦六日七分，每期三百六十六日，每四分。【按：「六日」當作「五日」，「四分」當作「四分日之一」。】

The trigram Kan is in the sixth position, Zhen in the seventh, Li in the eighth, and Dui in the ninth. These four trigrams are known as the four cardinal trigrams, used to symbolize the four seasons and four directions, referred to as the "Four Images." Each year has twelve months, and each month is assigned five trigrams. [Comment by the editors of the Siku Quanshu] The character "month" in "monthly May" should be read as "trigram." Each trigram occupies six days and seven parts, and each cycle totals three hundred sixty-six days, with an additional four parts added each year. [Comment by the editors of the Siku Quanshu] The term "six days" should be read as "five days," and "four parts" should be read as "one part of four days."

甲寅：伏羲氏至無懐氏五萬七千八百八十二年，神農五百四十年，黃帝一千五百二十年，少昊四百年，顓頊五百年，帝嚳三百五十年，堯一百年，舜五十年，禹四百三十一年，殷四百九十六年，周八百六十七年，秦五十年。已上六萬三千六百一十二年，庚戌年四百九十一年算上，右總六萬四千一百三年，相基加二年。【按：「基」當作「期」。】

Starting from Jiayin, the period from Fuxi to Wuhuai was 57,882 years, Shennong was 540 years, the Yellow Emperor was 1,520 years, Shaohao was 400 years, Zhuanyu was 500 years, Di Ku was 350 years, Tang Yao was 100 years, Yu Shun was 50 years, Xia Yu was 431 years, Yin Shang was 496 years, the Zhou dynasty was 867 years, and the Qin dynasty was 50 years. The total is 63,612 years. Adding the 491 years from Gengxu onwards, the total becomes 64,133 years, and adding two more years to the consecutive periods. [Comment by the editors of the Siku Quanshu] The character 'ji' should be 'qi'.

推軌當日術曰：置軌，以其歳之日除之，得軌，不盡日，每分即日之分也。推折當日術曰：以二十四除折數，所得是日軌。折皆當歳之折，有餘如上。

The method to calculate the day corresponding to the 'track' number is: first list the track number, divide it by the number of days in the current year to get the track; the remainder, each part corresponds to a fraction of a day. The method to calculate the day corresponding to the 'fold' number is: divide the fold number by twenty-four, and the result is the track for that day. All fold numbers are based on the current year's fold number, and if there is a remainder, handle it as described above.

The twelve message hexagrams each have three sequence numbers: The hexagram of Return has the numbers one, thirteen, and twenty-five; the hexagram of Approach has two, fourteen, and twenty-six; the hexagram of Great Communication has three, fifteen, and twenty-seven; the hexagram of Great Strength has four, sixteen, and twenty-eight; the hexagram of Decision has five, seventeen, and twenty-nine; the hexagram of Heaven has six, eighteen, and thirty; the hexagram of Meeting has seven, nineteen, and thirty-one; the hexagram of Withdrawal has eight, twenty, and thirty-two; the hexagram of Non-Communication has nine, twenty-one, and thirty-three; the hexagram of Observation has ten, twenty-two, and thirty-four; the hexagram of Reduction has eleven, twenty-three, and thirty-five; the hexagram of Earth has twelve, twenty-four, and thirty-six. [Comment by the editors of the Siku Quanshu] The above thirty-six numbers are arranged in a cyclical manner. Originally, the numbers under the hexagrams of Observation, Reduction, and Earth were all lost, and they have now been restored. Following this, Zhen is thirty-seven, Xun is thirty-eight, Kan is thirty-nine, Li is forty, Gen is forty-one, and Dui is forty-two.

【已上勾者，是勘銘軌加之，本經並無，只有單數不勾耳。○按：此條乃後人標識之辭，原本混入正文，今姑存其舊，而用細字夾註以別之。】右易姓四十二，消息三十六，六子在其數，合八十四戒，各有所繫而出之。純徳有七，其三法天，其四法地。【天三者，三六十八；地四者，四六二十四。】

[Old annotations] The markings added with hooks are those added during the collation of the text, not present in the original text; only the single numbers are without hooks. [Comment by the editors of the Siku Quanshu] This passage is a later addition made by someone to indicate certain points. Originally, it was mixed into the main text, but now it is preserved in its original form, distinguished by being written in small characters as a marginal note. The numbers listed on the right: the number of changes of dynasties is forty-two, the number of messages is thirty-six. The six sons of Zhen, Kan, Gen, Xun, Li, and Dui are included in these numbers, making a total of eighty-four prohibitions, each associated with its own category and separately derived. Pure virtue has seven items, three of which are modeled after Heaven and four are modeled after Earth. [Zheng Xuan's commentary] The three items modeled after Heaven are three times six, which equals eighteen; the four items modeled after Earth are four times six, which equals twenty-four.

六十四卦策術曰：陽爻九，【以四時乘之，得三十六。】陰爻六。【以四時乘之，得二十四。】軌術曰：陽爻九七，【各以四時乘之而並倍之，得一百二十八。】陰爻八六。【各以四時乘之而並倍之，得一百一十二。】

The method for calculating the numbers in the sixty-four hexagrams is: for a yang line, use nine. According to Zheng Xuan's commentary, multiply by the number four of the four seasons, resulting in thirty-six. For a yin line, use six. According to Zheng Xuan's commentary, multiply by the number four of the four seasons, resulting in twenty-four. The method for calculating the track numbers is: for a yang line, use nine and seven. According to Zheng Xuan's commentary, multiply each by the number four of the four seasons, then add them together and double the result, resulting in one hundred and twenty-eight. For a yin line, use eight and six. According to Zheng Xuan's commentary, multiply each by the number four of the four seasons, then add them together and double the result, resulting in one hundred and twelve.

假令乾六位，老陽爻，【九，四時乘之，四九三十六。】以三十六乘六爻，得二百一十六。少陽爻七，【以四時乘之，四七二十八。○按：二語應作夾註，原本混入正文，今改正。】以二十八乘之六爻，得一百六十八。已上二數合得三百八十四，因而倍之，有七百六十八。

For example, the Qian hexagram has six lines. If all are old yang lines, [Zheng Xuan's commentary] states that old yang is counted as nine. Using the number of the four seasons, multiply it by nine, four times nine equals thirty-six. Then multiply thirty-six by the six lines, resulting in two hundred and sixteen. If they are young yang lines, seven, [Zheng Xuan's commentary] says use the number of the four seasons to multiply, four times seven equals twenty-eight. [Commentary by the editors of the Siku Quanshu] These two sentences should be marginal notes, originally mixed into the main text, now corrected. Multiply twenty-eight by the six lines, resulting in one hundred and sixty-eight. Adding the two numbers together gives three hundred and eighty-four, then doubling it results in seven hundred and sixty-eight.

假令坤六位，老陰爻六，【四時乘之，四六二十四。】以二十四乘六爻，得一百四十四。少陰爻八，【四時乘之，四八三十二。】以三十二乘之六爻，得一百九十二。已上二數合得三百三十六，因而倍之，有六百七十二。乾坤二軌數合有一千四百四十。【他卦隨陰陽爻倍之。】凡陽爻用六十四為法乘，得倍之；凡陰爻用五十六為法乘，得數倍之。

For example, the Kun hexagram has six lines. If all are old yin lines (six), [Zheng Xuan's commentary] uses the number of the four seasons to multiply, four times six equals twenty-four. Then multiply twenty-four by the six lines, resulting in one hundred forty-four. If they are young yin lines (eight), [Zheng Xuan's commentary] uses the number of the four seasons to multiply, four times eight equals thirty-two. Then multiply thirty-two by the six lines, resulting in one hundred ninety-two. Adding the two numbers together gives three hundred thirty-six, and doubling it results in six hundred seventy-two. The combined number for the Qian and Kun hexagrams is one thousand four hundred forty. [Zheng Xuan's commentary] other hexagrams are calculated in the same way according to the number of their yin and yang lines. All yang lines are multiplied by sixty-four, and then the result is doubled. All yin lines are multiplied by fifty-six, and then the result is also doubled.

推一百九十二爻術曰：置六十四卦折半，有三十二，以六乘之，得陽爻一百九十二，陰爻亦一百九十二，合二數得三百八十四。又法：六爻以八乘之，得四十八；又八乘四十八，得三百八十四爻也。從伏羲天元甲寅已來，至大唐貞元年乙亥，積二百七十六萬一千二百二十算；至元和年三月，二百七十六萬一千二百三十一算。【按：此文至唐元和年，當亦後人所加，今退二字附書之。】

The method of calculating 192 lines is: take the 64 hexagrams and halve them to get 32, then multiply by 6 to get 192 yang lines; yin lines are also 192, adding them together gives 384 lines. Another method: one hexagram has six lines, multiply by 8 to get 48; then multiply 48 by 8 to get 384 lines. From Fuxi's heavenly stem Jiayin to a certain year Yihai in the reign of Emperor Zhongzhen of the Tang dynasty, there have been 2,761,220 calculations; by March of a certain year in the reign of Emperor Yuanhe, it is 2,761,231 calculations. [Comment by the editors of the Siku Quanshu] This text calculates up to the Yuanhe period of the Tang dynasty, which should also be added by later people. Now it is written in a lower position.
