featuretools.primitives.DistanceToHoliday#

class featuretools.primitives.DistanceToHoliday(holiday="New Year's Day", country='US')[source]#

Computes the number of days before or after a given holiday.

Description:

For a list of dates, return the distance from the nearest occurrence of a chosen holiday. The distance is returned in days. If the closest occurrence is prior to the date given, return a negative number.

If a date is missing, return NaN.

Currently only works with dates between 1950 and 2100.

Parameters:

  • holiday (str) – Name of the holiday. Defaults to New Year’s Day.

  • country (str) – Specifies which country’s calendar to use for the given holiday. Default is 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]
We can also control the country in which we’re searching for

a holiday.

>>> distance_to_holiday = DistanceToHoliday("Canada Day", country='Canada')
>>> dates = [datetime(2010, 1, 1),
...          datetime(2012, 5, 31),
...          datetime(2017, 7, 31),
...          datetime(2020, 12, 31)]
>>> distance_to_holiday(dates).tolist()
[181, 31, -30, 182]
