Besides being the base for the recurrence, - missing parameters in the final recurrence instances will also be - extracted from this date. If not given, datetime.now() will be used - instead. - :param interval: - The interval between each freq iteration. For example, when using - YEARLY, an interval of 2 means once every two years, but with HOURLY, - it means once every two hours. The default interval is 1. - :param wkst: - The week start day. Must be one of the MO, TU, WE constants, or an - integer, specifying the first day of the week. This will affect - recurrences based on weekly periods. The default week start is got - from calendar.firstweekday(), and may be modified by - calendar.setfirstweekday(). - :param count: - If given, this determines how many occurrences will be generated. - - .. note:: - As of version 2.5.0, the use of the keyword ``until`` in conjunction - with ``count`` is deprecated, to make sure ``dateutil`` is fully - compliant with `RFC-5545 Sec. 3.3.10 <https://tools.ietf.org/ - html/rfc5545#section-3.3.10>`_. Therefore, ``until`` and ``count`` - **must not** occur in the same call to ``rrule``. - :param until: - If given, this must be a datetime instance specifying the upper-bound - limit of the recurrence. The last recurrence in the rule is the greatest - datetime that is less than or equal to the value specified in the - ``until`` parameter. - - .. note:: - As of version 2.5.0, the use of the keyword ``until`` in conjunction - with ``count`` is deprecated, to make sure ``dateutil`` is fully - compliant with `RFC-5545 Sec. 3.3.10 <https://tools.ietf.org/ - html/rfc5545#section-3.3.10>`_.

Each integer will define an offset from the - Easter Sunday. Passing the offset 0 to byeaster will yield the Easter - Sunday itself. This is an extension to the RFC specification. - :param byweekno: - If given, it must be either an integer, or a sequence of integers, - meaning the week numbers to apply the recurrence to. Week numbers - have the meaning described in ISO8601, that is, the first week of - the year is that containing at least four days of the new year. - :param byweekday: - If given, it must be either an integer (0 == MO), a sequence of - integers, one of the weekday constants (MO, TU, etc), or a sequence - of these constants. When given, these variables will define the - weekdays where the recurrence will be applied. It's also possible to - use an argument n for the weekday instances, which will mean the nth - occurrence of this weekday in the period. For example, with MONTHLY, - or with YEARLY and BYMONTH, using FR(+1) in byweekday will specify the - first friday of the month where the recurrence happens.
