@sdetweil Ok - did that. No errors in the log but it doesn’t seem to be picking up the reoccurrence. Since that prior event isn’t upcoming over the next few days I can’t validate its not being listed , so I grabbed another one that has an occurrence tomorrow but isn’t showing up.

Here are all the relevant pieces
First a screenshot from Outlook.com

@sdetweil Thanks Sam

I see node-ical seemed to add support for Microsoft timezone names in this 2020 change
https://github.com/jens-maus/node-ical/pull/18/files/25bcb9d154d158c45ff0147e832425fafacfbeae#

And they have Central Standard Time in their test file. I thought this is what was used for parsing the ICS, is there another dependency or component involved?

I have been using MM many years with the same outlook.com based calendar. Reoccurring item issues have shown up here and there then they seem to go away, not sure if it was DST last week but they are back.

Note: the missing entries do show up in Calendar-Ext2 which I have also showing a calendar view.
I have tried updating the ical component to 17.0 and also to latest as advised in other recent threads with no change. Here is an example event that isn’t showing today but should - any guidance?

Magic mirror is up to date

I have it working but I don’t think you can do what you are trying to do in your config, CalendarExt2 overwrites everything so what I did was keep it in the same place on every page and then adjust the items around it. That is the only way to make it work - you can’t have it it one place on page one, try to change the view on page two

Start with a simple two page rotation with all the same modules showing (in the same places). Make sure it shows as the pages rotate
