@MarNog the Ext3 family of modules gets the events from the default calendar module Are the calendars on the same fetch cycle? We look back a year, and forward maxdays But the entire calendar is presented

@BKeyport Thanks a lot for pointing it out. I just realized that the third-party module list on the magicmirror.buider is not complete and the forum is an must go place for information and support. I have added MMM-CalendarEXT3Agenda and it is working. Of course it is not perfect, but I have posted a question related on the MMM-CalendarExt3Agenda main topic. Thank you folks very much!
