Both arguments can be `datetime.datetime`_, `datetime.date`_, tuples of numbers passed as arguments to `datetime.datetime`_ or strings in the form of\n``%Y%m%d`` (``yyyymmdd``) and ``%Y%m%dT%H%M%SZ`` (``yyyymmddThhmmssZ``).\nAdditionally, the ``end`` argument can be a ``datetime.timedelta`` to express that the end is relative to the ``start``.\nFor examples of arguments, see ``at(a_date)`` above.\n\n.. code-block:: python\n\n    \u003e\u003e\u003e query = recurring_ical_events.of(a_calendar)\n\n    # What happens in 2016, 2017 and 2018?\n    \u003e\u003e\u003e events = recurring_ical_events.of(a_calendar).between(2016, 2019)\n    \u003e\u003e\u003e len(events) # quite a lot is happening!\n    39\n\nThe resulting ``events`` are in a list of `icalendar events`_, see below.\n\n``after(earliest_end)``\n***********************\n\nYou can retrieve events that happen after a time or date using ``after(earliest_end)``.\nEvents that are happening during the ``earliest_end`` are included in the iteration.\n\n.. code-block:: python\n\n    \u003e\u003e\u003e earlierst_end = 2023\n    \u003e\u003e\u003e for i, event in enumerate(query.after(earlierst_end)):\n    ...     print(f\"{event['SUMMARY']} ends {event['DTEND'].dt}\") # all dates printed are after January 1st 2023\n    ...     if i \u003e 10: break  # we might get endless events and a lot of them!\n    Repair Café ends 2023-01-07 17:00:00+01:00\n    Repair Café ends 2023-02-04 17:00:00+01:00\n    Repair Café ends 2023-03-04 17:00:00+01:00\n    Repair Café ends 2023-04-01 17:00:00+02:00\n    Repair Café ends 2023-05-06 17:00:00+02:00\n    Repair Café ends 2023-06-03 17:00:00+02:00\n    Repair Café ends 2023-07-01 17:00:00+02:00\n    Repair Café ends 2023-08-05 17:00:00+02:00\n    Repair Café ends 2023-09-02 17:00:00+02:00\n    Repair Café ends 2023-10-07 17:00:00+02:00\n    Repair Café ends 2023-11-04 17:00:00+01:00\n    Repair Café ends 2023-12-02 17:00:00+01:00\n\n\n``all()``\n*********\n\nIf you wish to iterate over all occurrences of the components, then you can use ``all()``.\nSince a calendar can define a huge amount of recurring entries, this method generates them\nand forgets them, reducing memory overhead.\n\nThis example shows the first event that takes place in the calendar:\n\n.. code-block:: python\n\n    \u003e\u003e\u003e first_event = next(query.all()) # not all events are generated\n    \u003e\u003e\u003e print(f\"The first event is {first_event['SUMMARY']}\")\n    The first event is Weihnachts Repair-Café\n\n``count()``\n***********\n\nYou can count occurrences of events and other components using ``count()``.\n\n.. code-block:: python\n\n    \u003e\u003e\u003e number_of_TODOs = recurring_ical_events.of(a_calendar, components=[\"VTODO\"]).count()\n    \u003e\u003e\u003e print(f\"You have {number_of_TODOs} things to do!\")\n    You have 0 things to do!\n\n    \u003e\u003e\u003e number_of_journal_entries = recurring_ical_events.of(a_calendar, components=[\"VJOURNAL\"]).count()\n    \u003e\u003e\u003e print(f\"There are {number_of_journal_entries} journal entries in the calendar.\")\n    There are 0 journal entries in the calendar.\n\nHowever, this can be very costly!\n\n\n``events`` as list - ``at()`` and ``between()``\n***********************************************\n\nThe result of both ``between(start, end)`` and ``at(a_date)`` is a list of `icalendar events`_.\nBy default, all attributes of the event with repetitions are copied, like ``UID`` and ``SUMMARY``.\nHowever, these attributes may differ from the source event:\n\n* ``DTSTART`` which is the start of the event instance. (always present)\n* ``DTEND`` which is the end of the event instance. (always present)\n* ``RDATE``, ``EXDATE``, ``RRULE`` are the rules to create event repetitions.\n  They are **not** included in repeated events, see `Issue 23 \u003chttps://github.com/niccokunzmann/python-recurring-ical-events/issues/23\u003e`_.\n  To change this, use ``of(calendar, keep_recurrence_attributes=True)``.\n\nGenerator - ``after()`` and ``all()``\n*************************************\n\nIf the resulting components are ordered when ``after(earliest_end)`` or ``all()`` is used.\nThe result is an iterator that returns the events in order.\n\n.. code-block:: python\n\n    for event in recurring_ical_events.of(an_icalendar_object).after(datetime.datetime.now()):\n        print(event[\"DTSTART\"]) # The start is ordered\n\nPagination\n**********\n\nPagination allows you to chop the resulting components into chunks of a certain size.\n\n.. code-block:: python\n\n    # we get a calendar with 10 events and 2 events per page\n    \u003e\u003e\u003e ten_events = recurring_ical_events.example_calendar(\"event_10_times\")\n    \u003e\u003e\u003e pages = recurring_ical_events.of(ten_events).paginate(2)\n\n    # we can iterate over the pages with 2 events each\n    \u003e\u003e\u003e for i, last_page in enumerate(pages):\n    ...     print(f\"page: {i}\")\n    ...     for event in last_page:\n    ...         print(f\"-\u003e  {event.start}\")\n    ...     if i == 1: break\n    page: 0\n    -\u003e  2020-01-13 07:45:00+01:00\n    -\u003e  2020-01-14 07:45:00+01:00\n    page: 1\n    -\u003e  2020-01-15 07:45:00+01:00\n    -\u003e  2020-01-16 07:45:00+01:00\n\nIf you run a web service and you would like to continue pagination after a certain page,\nthis can be done, too.
