Hello,
What I’m looking for is a Birthday Calendar together with the National Holidays and the Daily appointments Agenda showing on the Magic Mirror with some application and the input comes from a easy to edit (external ?) c.s.v. file.
Till now for the National Holidays I found a possible solution with the Default MM Calendar or MMM-MyCalendar. Only with the last one I still don’t known how to configure it for 2 columns.

 config.js example i used for MMM-MyCalendar
 {
	//disabled: true,
	header: "Dagelijkse agenda en Verjaardagen.",
	module: "MMM-MyCalendar",
	position: "top_left",
	config: {
		maximumEntries: 8,
		calendars: [
				{
				symbol: "calendar-heck-o ", // waar is dit voor ?
				//url: "https://www.calendarlabs.com/templates/ical/US-Holidays.ics",
				url: "https://www.officeholidays.com/ics/ics_country_code.php?iso=NL",
				}
			]
		}
 },

And my second question is how to impliment my personal Birthday records. At this moment I have a hand written paper calendar in the toilet room on the first floor of our house. As you will find at many other families in the Netherlands ;-).
Is there a possibility todo this from a external c.s.v. file ?
What I need is a simple configuration example. Date, Time (start & duration), Name, Subject (Appointment, Birthday, Visiting), Destination where to go.
Can somebody help this newbee with this problem, but also I will learn about it how todo this in the future.
So please tell me also why.
