Python万年历（含农历、节气等）
前已在Python公历转换农历及简易万年历一文中实现农历计算的基本功能（内附农历计算原理），本篇利用这些功能完成UI小程序。

UI（以PyQt5为例）中使用Label控件显示月历，为完成点击后显示该日信息功能，需要对QLabel类添加单击函数。QComboBox的鼠标滚动功能默认滚动到最前或最末项后不再改变，需要重写wheelEvent事件使其在某年1月向上滚动时跳转到上一年12月。
Qt中每次设置样式表会清空原先的样式，故而选择使用html实现字体相关设置，保证设置样式表后字体不会变化，并且可通过获取Label文本判断日期类型。
虽然前已实现任意日期的公历转农历函数，但这里并不使用。如果每次点击标签都重新计算，会极大地增大计算量。本程序在每年内只计算一次，使用全局变量存储，跳转到年内其他月可以直接读取，无需重新计算。
程序中世纪列表提供前13世纪至30世纪，因为PyEphem库在计算BC13世纪至BC30世纪间的平均误差达2小时，导致确定农历月份容易出错，在早于BC13世纪前，误差更大。虽然在30世纪以后的较长时间内，ephem库的误差还很小，但也并非一般所需的功能。同时，对于特殊需求，程序中的年列表控件也开放了输入任意年份的功能。
