@Dennis-010 awesome, will need you to run it again with one debugging change

in calendarfetchutils.js
change this

					Log.debug(`event.recurrences: ${event.recurrences}`);

to this

			Log.debug("event.recurrences:" +JSON.stringify(event.recurrences));

but I really think its THIS

DTSTART;TZID="Amsterdam, Belgrade, Berlin, Brussels, Budapest, Madrid, Paris, Prague, Stockholm":20210415T190000
DTEND;TZID="Amsterdam, Belgrade, Berlin, Brussels, Budapest, Madrid, Paris, Prague, Stockholm":20210415T210000

the until is outside the event window start/end (04/15, this is 04/18) 
RRULE:FREQ=DAILY;UNTIL=20210418T170000Z

AND the event is in the past 2021
but the code tried to find recurrences THIS year

Tue Oct 24 2023 00:16:22 GMT+0200 (Midden-Europese zomertijd) and Tue Oct 22 2024 23:59:59 GMT+0200 (M>
[24.10.2023 00:16.22.051] [DEBUG] Title: xxx xxxx, with dates: [null,null,null,null]  <----- and returned junk.. those are bad dates.

sdetweil

@Dennis-010 try this

cd ~/MagicMirror/modules/default/calendar
cp calendarfetcherutils.js  utils.js
nano calendarfetcherutils.js

insert this line

						futureLocal = futureMoment.toDate(); // future
					}
					if(moment(endDate)>=moment(pastLocal)){ //<--- this line (approx line 283) 

						Log.debug(`Search for recurring events between: ${pastLocal} and ${futureLocal}`);
						const dates = rule.between(pastLocal, futureLocal, true, limitFunction);

and this line

							i
									description: description
								});
							}
						} // < ----- this line (approx line 454)
					}

this adds a check if the event end is after the calculated start (for include past events thats a year back) , then process the event, else skip it…

let me know

@sdetweil
This did the trick, thank you very much.

You are a genius!!
