Question

我正在使用pandas.tseries.holiday模块，并且在此模块中遇到了AbstractHolidayCalendar类的问题。用途是获取一个日历，该日历记录了前滚工作日的英国所有银行假日/周末。

我现有的代码（取自其他用户）是：

class EnglandAndWalesHolidayCalendar(AbstractHolidayCalendar):
rules = [Holiday('New Years Day', month=1, day=1, observance=next_monday),
         GoodFriday,
         EasterMonday,
         Holiday('Early May bank holiday',
             month=5, day=1, offset=DateOffset(weekday=MO(1))),
         Holiday('Spring bank holiday',
             month=5, day=31, offset=DateOffset(weekday=MO(-1))),
         Holiday('Summer bank holiday',
             month=8, day=31, offset=DateOffset(weekday=MO(-1))),
         Holiday('Christmas Day', month=12, day=25, observance=next_monday),
         Holiday('Boxing Day',
             month=12, day=26, observance=next_monday_or_tuesday)]

在上面提到的pandas模块中，我看到以下内容：

class AbstractHolidayCalendar(object):
    """
    Abstract interface to create holidays following certain rules.
    """
    __metaclass__ = HolidayCalendarMetaClass
    rules = []
    start_date = Timestamp(datetime(1970, 1, 1))
    end_date = Timestamp(datetime(2030, 12, 31))
    _cache = None

但是在添加

时

end_date = Timestamp(datetime(2080, 12, 31))

对于我定义的类，它似乎不起作用。有没有人知道如何调整结束日期而不直接更改pandas模块？感谢
