Python实现四柱八字排盘
其实八字排盘的程序时间再简单不过了，不过是年月日时分别除以60取余就好。不过Python的时间戳只支持到1970年，这也意味着1970年以前的八字是无法用python完成排盘的。
一、思路
首先，我们先把所有的二十四节气中的节以列表形式列出来。把时间输入进去后，放到列表里，根据输入时间在列表的位置，我们来确定年月日时的天干地支。
二、确定年月日时
__Jie = [19700105, 19700204, 19700306, 19700405, 19700506, 19700606, 19700707, 19700808, 19700908, 19701009, 19701108, 19701207, 19710106, 19710204, 19710306, 19710405, 19710506, 19710606, 19710708, 19710808,……]
这是所有节形成的列表，我们比如说1970年10月28，那么就是19701028放在列表中，求出这个值的index。这里是10，除以12（因为12个节是一年），所以1970年的天干地支就可以求出来了。
def Year(self):
if self.list_num in self.__Jie:
self.index_num = self.index_num + 1
self.__Jie.append(self.list_num)
self.__Jie.sort()
self.index_num = self.__Jie.index(self.list_num)
self.year_num = self.index_num // 12 + 1
self.year_tg = (self.year_num + 6) % 10
self.year_dz = (self.year_num + 8) % 12
self.tiangan_year = self.__Tian_Gan[self.year_tg]
self.dizhi_year = self.__Di_Zhi[self.year_dz]
return self.tiangan_year, self.dizhi_year
二、月的算法
月是同样的道理，只不过要除以60：
def Month(self):
self.month_num = self.index_num % 60
self.month_tg = (self.month_num + 3) % 10
self.month_dz = (self.month_num + 11) % 12
self.tiangan_month = self.__Tian_Gan[self.month_tg]
self.dizhi_month = self.__Di_Zhi[self.month_dz]
return self.tiangan_month, self.dizhi_month
三、日的算法
日最为简单，不需要查表。因为日就是60天一个循环，我们只需要把时间戳除以60，取余数就好。
def Day(self):
self.date_num = int((datetime.datetime(self.year, self.month, self.day) - self.stardard_day).days)
self.day_num = self.date_num % 60
self.day_tg = (self.day_num + 3) % 10
self.day_dz = (self.day_num + 3) % 12
self.tiangan_day = self.__Tian_Gan[self.day_tg]
self.dizhi_day = self.__Di_Zhi[self.day_dz]
self.hour_num = (datetime.datetime(self.year, self.month, self.day, self.hour) - self.stardard_day).seconds
if self.hour_num == 0:
self.tiangan_day = self.__Tian_Gan[self.day_tg + 1]
self.dizhi_day = self.__Di_Zhi[self.day_dz + 1]
return self.tiangan_day , self.dizhi_day
四、求时间的算法
由日推时有一个口诀，甲己还加甲 乙庚丙作初 丙辛从戊起 丁壬庚子居 戊癸何方发 壬子是真途，这说明，甲和己开头的日，那么这一日的子时是甲子时，后面以此类推。
这时候我们推时：
def Hour(self):
self.hour_num = int((datetime.datetime(self.year, self.month, self.day, self.hour) - self.stardard_day).seconds / 3600)
if self.hour_num == 0:
self.hour_dz = 1
self.day_tg = (self.day_tg + 1) % 10
if self.day_tg == 1 or self.day_tg == 6:
self.hour_tg = 1
elif self.day_tg == 2 or self.day_tg == 7:
self.hour_tg = 3
elif self.day_tg== 3 or self.day_tg == 8:
self.hour_tg = 5
elif self.day_tg == 4 or self.day_tg == 9:
self.hour_tg = 7
elif self.day_tg == 5 or self.day_tg == 0:
self.hour_tg = 9
else:
if self.hour_num % 2 == 0:
self.hour_dz = self.hour_num / 2 + 1
if self.day_tg == 1 or self.day_tg == 6:
self.hour_tg = (1 + self.hour_dz - 1) % 10
elif self.day_tg == 2 or self.day_tg == 7:
self.hour_tg = (3 + self.hour_dz - 1) % 10
elif self.day_tg == 3 or self.day_tg == 8:
self.hour_tg = (5 + self.hour_dz - 1) % 10
elif self.day_tg == 4 or self.day_tg == 9:
self.hour_tg = (7 + self.hour_dz - 1) % 10
elif self.day_tg == 5 or self.day_tg == 0:
self.hour_tg = (9 + self.hour_dz - 1) % 10
elif self.hour_num % 2 == 1:
self.hour_dz = (self.hour_num + 1) / 2
if self.day_tg == 1 or self.day_tg == 6:
self.hour_tg = (1 + self.hour_dz - 1) % 10
elif self.day_tg == 2 or self.day_tg == 7:
self.hour_tg = (3 + self.hour_dz - 1) % 10
elif self.day_tg == 3 or self.day_tg == 8:
self.hour_tg = (5 + self.hour_dz - 1) % 10
elif self.day_tg == 4 or self.day_tg == 9:
self.hour_tg = (7 + self.hour_dz - 1) % 10
elif self.day_tg == 5 or self.day_tg == 0:
self.hour_tg = (9 + self.hour_dz - 1) % 10
self.tiangan_hour = self.__Tian_Gan[self.hour_tg]
self.dizhi_hour = self.__Hour_Dz[self.hour_dz]
return self.tiangan_hour, self.dizhi_hour
五、求起运时间：
起运时间需要查表，根据阳男阴女顺排，阴男阳女逆排来和列表中上一个或者下一个值相减：
def QiYun(self): # sex:男为1，女为0
if (self.sex == 1 and self.year_tg % 2 == 1) or (self.sex == 0 and self.year_tg % 2 == 0):
self.jie_year = int(self.__Jie[self.index_num + 1] // 10000)
self.jie_month = int((self.__Jie[self.index_num + 1] - self.jie_year * 10000) // 100)
self.jie_day = int(self.__Jie[self.index_num + 1] % 10)
self.jie_date = datetime.datetime(self.jie_year, self.jie_month, self.jie_day)
self.jie_day_num = int((self.jie_date - self.input_day).days / 3)
if self.jie_day_num == 0:
self.jie_day_num = self.jie_day_num + 1
self.qiyun_year = self.year + self.jie_day_num
print(self.qiyun_year)
elif (self.sex == 1 and self.year_tg % 2 == 0) or (self.sex == 0 and self.year_tg % 2 == 1):
self.jie_year = int(self.__Jie[self.index_num - 1] // 10000)
self.jie_month = int((self.__Jie[self.index_num - 1] - self.jie_year * 10000) // 100)
self.jie_day = int(self.__Jie[self.index_num - 1] % 10)
self.jie_date = datetime.datetime(self.jie_year, self.jie_month, self.jie_day)
self.jie_day_num = int((self.input_day - self.jie_date).days / 3)
if self.jie_day_num == 0:
self.jie_day_num = self.jie_day_num + 1
self.qiyun_year = self.year + self.jie_day_num
return self.qiyun_year, self.__Sex[self.sex]
六、求空亡的算法
太简单了，我在我的八字课就这么教：地支数减去天干数的值和这个值减去1的值，就是空亡的地支代表的数字，如果小于0，结果加上12，以此求出空亡即可。比如壬午，壬9午7,7-9+12=10，所以空9和10，申和酉。
def KongWang(self):
if self.day_tg == 0:
self.day_tg = self.day_tg + 10
self.kongwang = self.day_dz + 2 - self.day_tg
if self.kongwang <= 0:
self.kongwang = self.kongwang + 12
self.kongwang1 = self.__Hour_Dz[self.kongwang - 1]
self.kongwang2 = self.__Hour_Dz[self.kongwang]
return self.kongwang1, self.kongwang2 # 空亡
七、大运的求法：
其余年份有了，大运就是从月柱衍生就好了：
def DaYun(self):
if (self.sex == 1 and self.year_tg % 2 == 1) or (self.sex == 0 and self.year_tg % 2 == 0):
i = 1
while i <= 7:
self.dayun_tg = self.month_tg + i
if self.dayun_tg >= 10:
self.dayun_tg = self.dayun_tg - 10
self.dayun_dz = self.month_dz + i
if self.dayun_dz >= 12:
self.dayun_dz = self.dayun_dz - 12
self.qiyun_y = self.qiyun_year + i * 10
i += 1
self.tiangan_dayun = self.__Tian_Gan[self.dayun_tg]
self.dizhi_dayun = self.__Di_Zhi[self.dayun_dz]
elif (self.sex == 1 and self.year_tg % 2 == 0) or (self.sex == 0 and self.year_tg % 2 == 1):
i = 1
while i <= 7:
self.dayun_tg = self.month_tg - i
if self.dayun_tg < 0:
self.dayun_tg = self.dayun_tg + 10
self.dayun_dz = self.month_dz - i
if self.dayun_dz < 12:
self.dayun_dz = (self.dayun_dz + 12) % 12
self.qiyun_y = self.qiyun_year + (i - 1) * 10
i += 1
self.tiangan_dayun = self.__Tian_Gan[self.dayun_tg]
self.dizhi_dayun = self.__Di_Zhi[self.dayun_dz]
return self.tiangan_dayun, self.dizhi_dayun, self.qiyun_y
