[SOLVED] Dates lower than Thu Jan 01 1970 00:00:00 GMT+0100 (CET) are not supported

Hi.

I’m trying to add a birthday calendar from my NexClound server, but it fails with the error “Error: dates lower than Thu Jan 01 1970 00:00:00 GMT+0100 (CET) are not supported”. The other calendars I’ve added works fine.

The dates added to this calendar reflects when the person is born, thus i have dates previous to 1970.

The complete error log i get is;

Any idea how to fix this?

This issue came up a couple of months ago. You can try a forum search to see if they came up with a fix. Temporarily, you could change the date in your calendar so it’s usable. Good luck

You need to edit the /home/pi/MagicMirror/node_modules/rrule-alt/lib/rrule.js file. See the post below.

https://forum.magicmirror.builders/topic/2208/calendar-shows-no-entries-after-mm-update/29?page=3

From the post…
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)
