I needed to import a heavily edited Google Calendar for further processing in Python on a local machine.
Certain events were initially created as instances of a recurring event, but then they were shifted or otherwise modifed.
As the result, the "ics" file exported by the Google Calendar could not be correctly interpreted by icalendar library.
The start date of the first event in the cycle (even though excluded) was displayed as the start date of the particular event.
The "ics" file itself is correct. After importing it to Thunderbird, the correct set of events is shown. Also the ical2htnl tool based on the old libical library generates the correct calendar. I attach an archive with the ics file exposing the problem and with the correct output generated by ical2html.
To Reproduce
Run the icalendar tool on the provided file:
icalendar linsw.ics
Find the "L5B G3" event in the output:
Summary : L5B G3 LINSW
Starts : Fri Mar 8 11:15:00 2024
End : Fri Mar 8 14:00:00 2024
Duration : 2:45:00
Location : Somewhere, Certain city

Attendees:
Run the ical2html file using the old libical library:
ical2html 20240201 P21W linsw.ics > linsw.html
You should get the HTML file with table, where "L5B G3" event is correctly scheduled on June 14.
Environment
OS: Debian/testing
Python version: Python 3.11.7
icalendar version: 5.0.11
Additional context
[ no ] I tested it with the latest version pip3 install https://github.com/collective/icalendar.git
[ yes ] I attached the ICS source file or there is no ICS source file
I couldnt test it with the latest version. An attempt to install it in a virtual environment resulted in another error:
