@Mykle1 That didn’t do it either. I stumbled upon this thread: https://forum.magicmirror.builders/topic/127/question-about-calendar/7

So I changed my config to:

            {
                    module: "calendar",
                    position: "top_left",
                    config: {
                            maximumEntries: "15",
                            maximumNumberOfDays: "30",
                            calendars: [
                                    {
                                            symbol: "calendar",
                                            url: "https://calendar.google.com/calendar/ical/private@group.calendar.google.com/private-private/basic.ics",
                                    }
                            ]
                    }
            },

And now it’s working. Woohoo!

Thanks anyways @Mykle1 !

@Mykle1 I’m gonna chalk that up to not enough coffee on my part. :)
