@KirAsh4 looks like latest calendar build has an issue with “broadcastPastEvents”

If I set it to true, it will not display any events. Calendar only works if set to false.

I solved this by going 1 line at a time. This // fixed my issue.

//		broadcastPastEvents: true,

I did an upgrade on MM to the latest version 2.22.0
After reboot, calendar no longer was displaying.
I have since made sure npm,node and electron are updated. I moved my MM directory and did a fresh install, restored the config.js file and still no go. Everything else on the system displays. I have tried different calendar links even, both public and private. I see in the log it gets the data:

Here is my config section, I did obfuscate the links:

{
      module: 'MMM-MonthlyCalendar',
      position: 'bottom_bar',
      config: {
        mode: 'fourWeeks'
      }
    },
    {
      module: 'calendar',
      header: 'Agenda',
      position: 'top_left',
      config: {
        fade: false,
        colored: true,
        wrapevents: true,
                maximumEntries: 10,
                broadcastPastEvents: true,
        maxTitleLength: 35,
                sliceMultiDayEvents: true,
                fetchInterval: 600000,
        calendars: [
          {
            symbol: 'chevron-circle-right',
            color: '#4285f4',
            url: 'https://calendar.google.com/calendar/ical/NONE%40gmail.com/private-655602d48f444d95a102537c39f35/basic.ics'
          },
          {
            symbol: 'football-ball',
                        color: '#009688',
            url: 'https://calendar.google.com/calendar/ical/NONE%40gmail.com/private-9555cf33931a454fa/basic.ics'
          }
        ]
      }
    },                  

After about 3 hours, I decided I would try reaching out to you experts. Cheers
