Error handling recurring events with timezones
Following code snippet do not yield the expected result:
from datetime import datetime
from icalevents.icalevents import events
import textwrap
import zoneinfo
tz = zoneinfo.ZoneInfo("Europe/Berlin")
ics = textwrap.dedent(

string_content=ics,

assert len(events) == 1
print(events[0])
I would expect the currently active recurring event instance. This holds for all start values of the last hour of the recurring event.

You're excluding the event by passing in a parse date range of 2022-01-11T07:00 - 2022-01-11T08:00, when the event is defined as repeating from 2021-11-29 - 2021-12-30.
Your code returns 0 events, which seems correct based on the calendar provided and the date range passed to events.
What date/time did you expect the single returned event to have?

Repeating until 20221230T230000Z -> 2022-12-30. So I expect the event with DTSTART;TZID=Europe/Berlin:20220111T000000 | DTEND;TZID=Europe/Berlin:20220111T080000 to be returned.
@chrko you are right! I have located the problem, that rule.between will not expand the event if it does not fit in the between definition. I will try to find a better solution. :-)
