Calendar shows "no entries" after MM Update

jasondreher

Is no one else having this issue? Besides the couple of us on this thread.

@sacha81 thats no problem. Export your large an old calender on your PC. Create a new calender an import the data. Delete all the data in your main calender and import the small calender, sort by my Python Skript. So you got one calender with your old data and one small with your 2017 datas.

I made a copy of my google calendar and cleaned out with https://chrome.google.com/webstore/detail/bulk-action-tool-for-goog/lkpgfdjgbcmeblffjfefgkhkneilhfnf now my ICS is 400kb but it still not load :(

I am still having this problem, but it might not be total related to size. I have a 2.43MB calendar that works fine and a 1.38MB calendar that will not display, both worked before the update. Has anyone found anything that works?

Thanks.

I removed all items until today, now my calendar (Google private ICS) has just events in the future and still does not load items on the mirror. Wondering whats changed in this version with the calendar :-(

Hi,
I am experiencing the same issue since the update to the current MM version 2.1.1 . I should have checked for issues beforehand :-/
EDIT: I have all my calendars on my owncloud on the same LAN. All of them work fine except a calendar with all birthdays.
Since I have no time to troubleshoot myself for the next month, I will have to wait for an official fix…
Let’s make MM great again ;-)

I fixed my issue. Some searching led me to this:
https://github.com/MichMich/MagicMirror/issues/791#issuecomment-289306407
No dates before 1970 are accepted - but in my birthday calendar I have created birthdays e.g. in 1946…
Thank you @amcolash

This is how you can check if this is why your calendar is not working:
ssh to your pi

cd /home/pi/MagicMirror
DIAPLAY=:0 npm start dev

If you see this in the output, you have dates in your calendar before 1970:

Whoops! There was an uncaught exception...

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

What I did to fix my birthday calendar: Edit this file

/home/pi/MagicMirror/node_modules/rrule-alt/lib/rrule.js

Go to line 56 or search for the first occurance of “ORDINAL_BASE” and change this line:

ORDINAL_BASE: new Date(1970, 0, 1),

set it to a lower year like 1900.
Then restart your magic mirror (pm2 restart mm)

And it’s (hopefully) GREAT AGAIN :-D :clap:

@tgeimer for me thats working THANK YOU !!!

I tried tgeimer’s fix (many thanks by the way), but without success. Of two calendars, only one displays. Here is the terminal output:

Whoops! There was an uncaught exception…

@Mitch1138
You have changed your ORDINAL_BASE to 1900, but it seems as if you have dates even before 1900 in your calendar as it tells you in line 2 of the exception:

Error: dates lower than Mon Jan 01 1900 00:00:00 GMT-0500 (EST) are not supported

What kind of calendar is it? Try to change the year to something even lower or even 0. Otherwise you can perhaps guess based on your calendar which entry might cause this error and change that recurring date…

Mitch1138

Excellent, changing the date to 1000 fixed it. It is a google calendar, but I have synced with outlook, iphone, etc. so are probably some odd dates and trash squirreled away.

Thanks very much

@Mitch1138 said in Calendar shows “no entries” after MM Update:

@tgeimer
You are awesome!
I was looking for a solution since I´ve updated MM but only now when I got the error message with the date 1970 I was able to find that thread and your solution. Now is working again. Thank you very much.

Befkef

So I’ve set the date to 1000… And even the beautiful year 0, but the only entry it shows is 1 entry which isn’t due in over 5 months… The calendar is very important for me so can anyone please help me!! Thnx in advance!!
