A simple tool to convert EuroPython's json files to an ICS file.
Clone EuroPython's website repo. Then install and use this tool:
python3 -m venv venv
source venv/bin/activate
pip install ./eventor
eventor -j '~/path/to/europython/website/src/content/days/*.json'This will write a calendar.ics file in the current directory that you can then import to your favorite calendar app.
