@MarcLandis I pushed a new branch

here is an UPDATED test version of the fixes for all kinds of calendar date problems.

NOTE: the changed branch name
NOTE: this used the node-cal@0.19.0 library UNCHANGED

best to make a new folder and git clone there

git clone https://github.com/sdetweil/MagicMirror
cd MagicMirror
git checkout fixcaldates2 // <------ note this is a changed branch name
npm run install-mm
copy your config.js and custom.css from the prior folder
and the non-default modules you have installed…

this ONLY changes the default calendar
but DOES ship an updated node-ical library too

if you need to fall back, just rename the folders around again so that
your original is called MagicMirror

all the testcases for node-ical and MagicMirror execute successfully.

the ‘BIG’ change here is to get the local NON-TZ dates for the
rrule.between()

all the checking and conversion code is commented out or not used
the node-ical fixes are for excluded dates (exdate) values being adjusted for DST/STD time… waiting to submit that PR

one fix in calendar.js for checking if a past date was too far back,
but it never checked to see IF the event date was in the past… (before today) so it chopped off too many

and one change in calendarfetcher.js to put out a better diagnostic message of the parsed data… (exdate was excluded cause JSON stringify couldn’t convert the complex structure)

I added the tests you all have documented

please re-pull and checkout the new branch (I deleted the old branch)
and npm run install-mm again
