      1   2017-12-31
      2   2018-01-01
      dtype: datetime64[ns]

      >>> dates.dt.is_year_end
      0    False
      1     True
      2    False
      dtype: bool

      >>> idx = pd.date_range("2017-12-30", periods=3)
      >>> idx
      DatetimeIndex(['2017-12-30', '2017-12-31', '2018-01-01'],
                    dtype='datetime64[ns]', freq='D')
