featuretools.primitives.NUniqueDaysOfCalendarYear#

class featuretools.primitives.NUniqueDaysOfCalendarYear[source]#

Determines the number of unique calendar days.

Description:

Given a list of datetimes, return the number of unique calendar days. The same date in two different years is counted as one. So Feb 21, 2017 is not unique from Feb 21, 2019.

Examples

>>> from datetime import datetime
>>> n_unique_days_of_calendar_year = NUniqueDaysOfCalendarYear()
>>> times = [datetime(2019, 2, 1),
...          datetime(2019, 2, 1),
...          datetime(2018, 2, 1),
...          datetime(2019, 1, 1)]
>>> n_unique_days_of_calendar_year(times)
