土为雨化，火热化，金清化，木风化，水寒化。丁丑、丁未年，其连风清热，清热胜复同。
丁乃木运，风化。木运之下，金气承之，清化。木生火，火乃热化。癸丑、癸未年，其运热寒雨，
寒雨胜复同。癸乃火运，热化。火运之下，水气承之，寒化。火生土，土乃雨化。己丑、己未年，
其运雨风清，风清胜复同。己乃土运，雨化。土运之下，木气承之，木乃风化。土生金，金乃清化。
其运者，阴年不及，与所克所生者同化也，乃邪气化度也。阳年太过，运只一化，乃正气
化度也。此乃邪正二化也。
自大唐麟德元年甲子岁正月一日己酉朔，娄金独直日先下，积年乃减一算。（自麟德至庚戌，
五百二十七年也，明昌元年也。）次以七因之，以十九除之，一名闰数。次以十二乘之，后却加
入闰数、除数，后又加入本月数。此下位，别张之，乃去一年。次出其闰数，又虚去其五行数。
次以上位，进之一位，后三因之。次出下位之数，名去小尽也。后加入月下零日数，看得几日。
次六十除之，不尽，乃百粟之。又以八十七除之，不尽者，乃加入运数，太过加成数，不及加生
数，看得几何。如阳年逢偶数，即加一，阴年逢奇数，即减一，其余加减，毕其数过，当日下刻
中之数也。
凡五运，皆主一年。太过来早，不及乘之，不及来晚，太过从之。运来之日，在司天交司日
前后各十三日，或同交司日齐。大至者，每岁冬至天正之日也。冬至后一月，即丑正大寒之日，
是天交司之日也，斗建丑正。阳年交司日前十三日至，阴年交司日后十三日至。年支运干相符，
合德而平气也。既非有余，又非不及，日平气也。即土运取己丑、己未，金运取乙酉，水运取辛
亥，木运取丁卯，火运取癸巳。此皆阴年不及运，反作平气运也。又于太过年，
当有余而天刑之，反作平气，不得其盛也。火运天刑有二，即戊辰、戊戌，上见太阳，寒水司天
克之，不盛也，故做平气运。金运天刑有四，即庚子、庚午、庚寅、庚申，即君相二火司天，故
上见二火，中见金运。司天刑之，不得有余，故作平气也，皆同天至交司日也。太过曰先天，不
及曰后天，平气曰齐天。齐天者，即同至于大寒交司日也。
土运对应雨化，火运对应火热化，金运对应清化，木运对应风化，水运对应寒化。丁丑年和丁未年，其连带的风、热、清、热之化，清热胜复同时存在。
丁属木运，表现为风化。在木运之下，有金气制约它，表现为清化。木生火，火表现为热化。癸丑年和癸未年，其运行为热、寒、雨，寒雨胜复同时存在。
癸属火运，表现为热化。在火运之下，有水气制约它，表现为寒化。火生土，土表现为雨化。己丑年和己未年，其运行为雨、风、清，风清胜复同时存在。
己属土运，表现为雨化。在土运之下，有木气制约它，木表现为风化。土生金，金表现为清化。
所谓“运”，是指阴年（不及之年）的运气，与它所克和所生的五行同化，这是邪气化度。阳年（太过之年）的运气只有一种化象，这是正气化度。这就是邪正二化。
从大唐麟德元年甲子岁正月一日己酉朔开始，娄金独直日先下，累计年份后减一算。（自麟德至庚戌，共五百二十七年，即明昌元年。）接着乘以七，除以十九，称为闰数。再乘以十二，然后加入闰数和除数，再加入本月数。将此置于下位，另列一行，减去一年。再取出闰数，又空去五行数。
接着将上位进一位，乘以三。再取出下位的数，称为去小尽。然后加入月下的零日数，得出几天。再用六十除，有余数，则用一百除。再用八十七除，有余数的，则加入运数，太过之年加成数，不及之年加生数，得出数值。如果是阳年遇到偶数，就加一；阴年遇到奇数，就减一。其余加减完成后，如果总数超过，取当日下刻中之数。
凡五运，都主管一年。太过之年来得早，不及之年会乘虚而入；不及之年来得晚，太过之年会顺从它。运来之日，在司天交司日前后各十三天，或者与交司日相同。最大的节气是每年的冬至天正之日。冬至后一个月，就是丑月正大寒之日，是天交司之日，斗柄指向丑正。阳年交司日前十三天到达，阴年交司日后十三天到达。年支与运干相符，合德而成为平气。既非有余，也非不及，称为日平气。即土运取己丑、己未年，金运取乙酉年，水运取辛亥年，木运取丁卯年，火运取癸巳年。这些都是阴年不及之运，反而成为平气运。另外在太过之年，本应有余却被天刑克制，反而成为平气，不能保持旺盛。火运的天刑有两个年份，即戊辰、戊戌年，上见太阳寒水司天克制它，不旺盛，所以做平气运。金运的天刑有四个年份，即庚子、庚午、庚寅、庚申年，即君火和相火司天，所以上见二火，中见金运。司天克制它，不能有余，所以做平气，这些都同于天至交司日。太过称为先天，不及称为后天，平气称为齐天。齐天者，即同于大寒交司日。
Earth corresponds to Rain Transformation, Fire corresponds to Heat Transformation, Metal corresponds to Clearing Transformation, Wood corresponds to Wind Transformation, and Water corresponds to Cold Transformation. In Ding Chou (丁丑) and Ding Wei (丁未) years, the associated transformations of Wind, Heat, Clearing, and Heat involve simultaneous Sheng-Fu (Victory and Revenge) dynamics between Clearing and Heat.
Ding represents Wood Movement, manifesting as Wind Transformation. Below Wood Movement, Metal Qi constrains it, manifesting as Clearing Transformation. Wood generates Fire, so Fire manifests as Heat Transformation. In Gui Chou (癸丑) and Gui Wei (癸未) years, the movement involves Heat, Cold, and Rain, with simultaneous Sheng-Fu dynamics between Cold and Rain.
Gui represents Fire Movement, manifesting as Heat Transformation. Below Fire Movement, Water Qi constrains it, manifesting as Cold Transformation. Fire generates Earth, so Earth manifests as Rain Transformation. In Ji Chou (己丑) and Ji Wei (己未) years, the movement involves Rain, Wind, and Clearing, with simultaneous Sheng-Fu dynamics between Wind and Clearing.
Ji represents Earth Movement, manifesting as Rain Transformation. Below Earth Movement, Wood Qi constrains it, so Wood manifests as Wind Transformation. Earth generates Metal, so Metal manifests as Clearing Transformation.
The term "Movement" refers to Yin years (Deficient years), where the Qi transforms in accordance with what it controls and what it generates; this is the degree of Evil Qi transformation. Yang years (Excessive years) have only one type of transformation, which is the degree of Righteous Qi transformation. This constitutes the two transformations of Evil and Righteousness.
Starting from the first day of the first month of Jia Zi year in the Lin De era of the Great Tang, when Ji You was the new moon, Lou Jin (Metal Star) independently directed the day initially, and after accumulating years, subtract one calculation. (From Lin De to Geng Xu, there are five hundred and twenty-seven years, which is the first year of Ming Chang.) Then multiply by seven, divide by nineteen, named Leap Number. Then multiply by twelve, then add the Leap Number and Divisor, then add the current month's number. Place this in the lower position, list separately, subtract one year. Then extract the Leap Number, and vacate the Five Elements number.
Then advance the upper position by one place, multiply by three. Then extract the number from the lower position, named Removing Small Month End. Then add the fractional days under the month, to see how many days remain. Then divide by sixty, if there is a remainder, divide by one hundred. Then divide by eighty-seven, if there is a remainder, add the Movement Number: for Excessive years add the Completion Number, for Deficient years add the Generation Number, to see the quantity. If a Yang year encounters an even number, add one; if a Yin year encounters an odd number, subtract one. After completing other additions and subtractions, if the total exceeds, take the number at the middle of the next ke (time unit) of that day.
All Five Movements govern one year. Excessive movements arrive early, and Deficient movements take advantage of them; Deficient movements arrive late, and Excessive movements follow them. The day the Movement arrives is thirteen days before or after the Si Tian (Heavenly Ruler) Jiao Si (Exchange) day, or coincides with the Jiao Si day. The greatest solar term is the Winter Solstice Tian Zheng day. One month after Winter Solstice is the day of Da Han (Great Cold) in the Chou month, which is the Heavenly Jiao Si day, with the Dipper pointing to Chou Zheng. Yang year Jiao Si days arrive thirteen days before, Yin year Jiao Si days arrive thirteen days after. When the Year Branch and Movement Stem match, they combine virtue to form Ping Qi (Balanced Qi). Neither excessive nor deficient, it is called Day Ping Qi. Thus, Earth Movement takes Ji Chou (己丑) and Ji Wei (己未) years, Metal Movement takes Yi You (乙酉) year, Water Movement takes Xin Hai (辛亥) year, Wood Movement takes Ding Mao (丁卯) year, Fire Movement takes Gui Si (癸巳) year. These are all Yin year Deficient Movements that reverse to become Balanced Qi Movements. Furthermore, in Excessive years, although there should be excess, Heavenly Punishment restricts it, reversing to Balanced Qi, preventing it from being vigorous. There are two Heavenly Punishments for Fire Movement, namely Wu Chen (戊辰) and Wu Xu (戊戌) years, where Taiyang (Solar) Cold Water rules the sky and controls it, so it is not vigorous, thus becoming Balanced Qi. There are four Heavenly Punishments for Metal Movement, namely Geng Zi (庚子), Geng Wu (庚午), Geng Yin (庚寅), and Geng Shen (庚申) years, where Jun Huo (Monarch Fire) and Xiang Huo (Minister Fire) rule the sky, so above sees the two Fires, and in the middle sees Metal Movement. The ruling Heaven controls it, preventing excess, thus becoming Balanced Qi. All these are the same as the Tian Zhi (Heavenly Arrival) Jiao Si day. Excessive is called Xian Tian (Prior Heaven), Deficient is called Hou Tian (Posterior Heaven), Balanced Qi is called Qi Tian (Equal Heaven). Qi Tian means coinciding with the Da Han Jiao Si day.
