It accepts all the keywords defined in the RFC as its constructor parameters (except byday, which was renamed to byweekday) and more. The constructor prototype is:: rrule(freq) Where freq must be one of YEARLY, MONTHLY, WEEKLY, DAILY, HOURLY, MINUTELY, or SECONDLY. .. note:: Per RFC section 3.3.10, recurrence instances falling on invalid dates and times are ignored rather than coerced: Recurrence rules may generate recurrence instances with an invalid date (e.g., February 30) or nonexistent local time (e.g., 1:30 AM on a day where the local time is moved forward by an hour at 1:00 AM). Such recurrence instances MUST be ignored and MUST NOT be counted as part of the recurrence set. This can lead to possibly surprising behavior when, for example, the start date occurs at the end of the month: >>> from dateutil.rrule import rrule, MONTHLY >>> from datetime import datetime >>> start_date = datetime(2014, 12, 31) >>> list(rrule(freq=MONTHLY, count=4, dtstart=start_date)) ... # doctest: +NORMALIZE_WHITESPACE [datetime.datetime(2014, 12, 31, 0, 0), datetime.datetime(2015, 1, 31, 0, 0), datetime.datetime(2015, 3, 31, 0, 0), datetime.datetime(2015, 5, 31, 0, 0)] Additionally, it supports the following keyword arguments: :param dtstart: The recurrence start. 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>`_. Therefore, ``until`` and ``count`` **must not** occur in the same call to ``rrule``. :param bysetpos: If given, it must be either an integer, or a sequence of integers, positive or negative. Each given integer will specify an occurrence number, corresponding to the nth occurrence of the rule inside the frequency period. For example, a bysetpos of -1 if combined with a MONTHLY frequency, and a byweekday of (MO, TU, WE, TH, FR), will result in the last work day of every month. :param bymonth: If given, it must be either an integer, or a sequence of integers, meaning the months to apply the recurrence to. :param bymonthday: If given, it must be either an integer, or a sequence of integers, meaning the month days to apply the recurrence to. :param byyearday: If given, it must be either an integer, or a sequence of integers, meaning the year days to apply the recurrence to. :param byeaster: If given, it must be either an integer, or a sequence of integers, positive or negative. 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. Notice that in the RFC documentation, this is specified as BYDAY, but was renamed to avoid the ambiguity of that keyword. :param byhour: If given, it must be either an integer, or a sequence of integers, meaning the hours to apply the recurrence to. :param byminute: If given, it must be either an integer, or a sequence of integers, meaning the minutes to apply the recurrence to. :param bysecond: If given, it must be either an integer, or a sequence of integers, meaning the seconds to apply the recurrence to. :param cache: If given, it must be a boolean value specifying to enable or disable caching of results. If you will use the same rrule instance multiple times, enabling caching will improve the performance considerably.

This occurs whenever the interval is not coprime with the base of a given unit and the difference between the starting position and the ending position is not coprime with the greatest common denominator between the interval and the base. For example, with a FREQ of hourly starting at 17:00 and an interval of 4, the only valid values for BYHOUR would be {21, 1, 5, 9, 13, 17}, because 4 and 24 are not coprime. :param start: Specifies the starting position. :param byxxx: An iterable containing the list of allowed values. :param base: The largest allowable value for the specified frequency (e.g. 24 hours, 60 minutes). This does not preserve the type of the iterable, returning a set, since the values should be unique and the order is irrelevant, this will speed up later lookups.
