在基于《易经》的占卜中，无论是八字、六壬、奇门，小至梅花，六爻，都需要用到旺衰。所谓旺衰，即一个五行在不同季节的不同状态：
在春天，木火旺，其他五行衰；
在夏天，火土旺，其他五行衰；
在秋天，金水旺，其他五行衰；
在冬天，水木旺，其他五行衰；
因为季节是和节气相关的，那么我们首先应该先确定当下时间的节气，我们把节气建立成一个列表。

节气有了，我们首先要做的就是计算出当下时间所对应季节：
self.celander = self.year * 10000 + self.month * 100 + self.day
if self.celander in self.__Li:
self.celander = self.celander + 1
self.int_celander = int(self.celander)
self.__Li.append(self.int_celander)
self.__Li.sort()
self.result = int(self.__Li.index(self.int_celander))
self.final_result = self.result % 4
self.__Li.remove(self.int_celander)
if self.final_result == 0:
return None
# return self.__Jijie[self.final_result]
return self.__Jijie[self.final_result]
即将输入的时间放置在列表中，并通过list.index来求出这个季节所在列表的位置。得到位置后，除以4取余，即是所在的季节。
季节有了，旺衰就很好求了。
def Judge_WangShuai(self, *args): # 各季节中五行的旺衰
self.season = self.__LeiXiang[self.final_result]
# print(self.season)
self.args = args
for self.item in self.args:
if self.item in self.season:
self.qiang.append(self.item)
else:
self.ruo.append(self.item)
return (self.qiang, self.ruo)
