In its simplest form:
config: {
calendars: [
{
url: 'webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics'
},
{
url: 'https://calendar.google.com/calendar/ical/FILL_IN_YOUR_INFO'
},
],
}
To get your Google Calendar link, look in your calendar settings. You want to use the private ICAL address. Note that it will only display what is on the default calendar. The way Google split Birthdays from the default calendar makes it so those don’t show up (and they aren’t providing an ICAL link to the Birthdays one either - this is a major complaint from many.) And if you have multiple calendars created, you need to include each one separately.
