Copy

>>> idx = pd.date_range(start='2018-01-01', freq='D', periods=3)
>>> idx
DatetimeIndex(['2018-01-01', '2018-01-02', '2018-01-03'], dtype='datetime64[ns]', freq=None)
>>> idx.day_name()  
Index(['Monday', 'Tuesday', 'Wednesday'], dtype='object')

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 = pd.date_range(start='2018-01-01', freq='D', periods=3)
>>> idx
DatetimeIndex(['2018-01-01', '2018-01-02', '2018-01-03'], dtype='datetime64[ns]', freq=None)
>>> idx.day_name(locale='pt_BR.utf8')  
Index(['Segunda', 'Terça', 'Quarta'], dtype='object')
