Parameters:

  • holiday (str) – 假日的名称.默认为元旦.

  • country (str) – 指定使用哪个国家的日历来确定假日. 默认为 US.

Examples

>>> from datetime import datetime
>>> distance_to_holiday = DistanceToHoliday("New Year's Day")
>>> dates = [datetime(2010, 1, 1),
...          datetime(2012, 5, 31),
...          datetime(2017, 7, 31),
...          datetime(2020, 12, 31)]
>>> distance_to_holiday(dates).tolist()
[0, -151, 154, 1]

我们还可以控制搜索假日的国家.

>>> distance_to_holiday = DistanceToHoliday("Canada Day", country='Canada')
>>> dates = [datetime(2010, 1, 1),
...          datetime(2012, 5, 31),
...          datetime(2017, 7, 31),
