Examples

>>> import maxframe.dataframe as md
>>> s = md.Series(md.date_range(start="2018-01-01", freq="D", periods=3))
>>> s.execute()
0   2018-01-01
1   2018-01-02
2   2018-01-03
dtype: datetime64[us]
>>> s.dt.day_name().execute()
0       Monday
1      Tuesday
2    Wednesday
dtype: str

>>> idx = md.date_range(start="2018-01-01", freq="D", periods=3)
>>> idx.execute()
DatetimeIndex(['2018-01-01', '2018-01-02', '2018-01-03'],
              dtype='datetime64[us]', freq='D')
>>> idx.day_name().execute()
Index(['Monday', 'Tuesday', 'Wednesday'], dtype='str')

Using the locale parameter you can set a different locale language, for example: idx.day_name(locale='pt_BR.utf8') will return day names in Brazilian Portuguese language.

>>> idx = md.date_range(start="2018-01-01", freq="D", periods=3)
>>> idx.execute()
DatetimeIndex(['2018-01-01', '2018-01-02', '2018-01-03'],
              dtype='datetime64[us]', freq='D')
>>> idx.day_name(locale="pt_BR.utf8")
Index(['Segunda', 'Terça', 'Quarta'], dtype='str')
