How to include end date in pandas date_range method?

Question

From pd.date_range(\'2016-01\', \'2016-05\', freq=\'M\', ).strftime(\'%Y-%m\'), the last month is 2016-04, but I was expecting it to be 2016

Answer 1

A way to do it without messing with figuring out month ends yourself.

pd.date_range(*(pd.to_datetime(['2016-01', '2016-05']) + pd.offsets.MonthEnd()), freq='M')

DatetimeIndex(['2016-01-31', '2016-02-29', '2016-03-31', '2016-04-30',
           '2016-05-31'],
          dtype='datetime64[ns]', freq='M')
