featuretools.primitives.DateToHoliday

class featuretools.primitives.DateToHoliday(country='US')

Transforms time of an instance into the holiday name, if there is one.

Description:

If there is no holiday, it returns NaN. Currently only works for the United States and Canada with dates between 1950 and 2100.

Parameters:

country (str) – Country to use for determining Holidays. Default is ‘US’. Should be one of the available countries here: https://github.com/dr-prodigy/python-holidays#available-countries

Examples

>>> from datetime import datetime
>>> date_to_holiday = DateToHoliday()
>>> dates = pd.Series([datetime(2016, 1, 1),
...          datetime(2016, 2, 27),
...          datetime(2017, 5, 29, 10, 30, 5),
...          datetime(2018, 7, 4)])
>>> date_to_holiday(dates).tolist()
["New Year's Day", nan, 'Memorial Day', 'Independence Day']

We can also change the country.

>>> date_to_holiday_canada = DateToHoliday(country='Canada')
>>> dates = pd.Series([datetime(2016, 7, 1),
...          datetime(2016, 11, 15),
...          datetime(2018, 12, 25)])
>>> date_to_holiday_canada(dates).tolist()
['Canada Day', nan, 'Christmas Day']
