Dateutil.rrule.rrule.between () gives only dates after

Question

In the IPython console:

In [16]: b Out[16]: datetime.datetime(2008, 3, 1, 0, 0) In [17]: e Out[17]: datetime.datetime(2010, 5, 2, 0, 0) In [18]: rrule(MONTHLY).between(b, e, inc=True) Out[18]: [datetime.datetime(2009, 3, 6, 14, 42, 1), datetime.datetime(2009, 4, 6, 14, 42, 1), datetime.datetime(2009, 5, 6, 14, 42, 1), datetime.datetime(2009, 6, 6, 14, 42, 1), datetime.datetime(2009, 7, 6, 14, 42, 1), datetime.datetime(2009, 8, 6, 14, 42, 1), datetime.datetime(2009, 9, 6, 14, 42, 1), datetime.datetime(2009, 10, 6, 14, 42, 1), datetime.datetime(2009, 11, 6, 14, 42, 1), datetime.datetime(2009, 12, 6, 14, 42, 1), datetime.datetime(2010, 1, 6, 14, 42, 1), datetime.datetime(2010, 2, 6, 14, 42, 1), datetime.datetime(2010, 3, 6, 14, 42, 1), datetime.datetime(2010, 4, 6, 14, 42, 1)] 

How do I make between() return dates starting from start date ( b )?

Answer 1

You need to pass b to rrule, for example:

 rrule(MONTHLY, dtstart = b).between(b, e, inc=True) 

From these docs ( http://labix.org/python-dateutil ), this is like calling rrule without specifying dtstart will use datetime.datetime.now () as the starting point for the sequence that you later apply between to. That is why your values ​​begin with 2009-03-06.
