<font size="+1">If the Provider for Google Calendar is retired in
favor of CalDAV, how do I get the other calendars Google provides
for my local sports teams and US Holidays?<br>
<br>
I tried CalDAV in Daily and adding a .ics(?) calendar for the
local baseball team from mlb.com and the thing annoyed me with a
reminder before every game.<br>
<br>
Nice to see the provider extension back for Daily, Thanks!<br>

lovers of Thunderbird and calendaring,
<br>
<br>
have you ever asked yourself where one of the "productivity
components", the Thunderbird Calendar is going?
<br>
<br>
Since TB 38 it's being shipped with Thunderbird on an "opt out"
basis, lately it even changed its version numbering scheme from
(TB version + 2) / 10 to just using the TB version[1].
<br>
<br>
But what's happening otherwise?
<br>
<br>
Long-standing bugs that have been astonishing the community like
the inability to process more than one invitation per message[2]
or the ability to double-click ICS attachments and process them[3]
haven't been addressed for more than a decade now.
<br>
<br>
Most if not all volunteer Calendar contributors have left, unless
Thunderbird hired them[4].
<br>
<br>
The Calendar blog[5] hasn't seen an update in two years.
<br>
<br>
Bug triaging is lagging behind[6].
<br>
<br>
The module page[7] is deserted. I've been on the project since
2015 and from the people listed on the page, I've only met
Philipp, the module owner.
<br>
<br>
And there are administrative delays that affect Thunderbird as a
whole: Slow reviews of patches (including those of potential new
contributors), slow uplift/backport approvals of patches to beta
and ESR versions, slow Bugzilla administration, delay of many
months to provide the Lightning add-on at addons.thunderbird.net
for those using a distribution which doesn't package it[8][9].
<br>
<br>
Apart from the long-standing issues mentioned above, there are
also questions reaching into the future:
<br>
<br>
Why not integrate the calendar functionality completely into
Thunderbird and not ship it as add-on? That would solve endless
incompatibility and up/downgrade woes[10][11].
<br>
<br>
The Calendar code is still using XUL overlays. What's the future
of that[12]?
<br>
<br>
What about the "Provider for Google Calendar" add-on[13]? Can that
be retired in favour of CalDAV? The test to make sure it still
works has been switched off in August 2018[14].
<br>
<br>
And finally: What's happening with ical.js, the JavaScript library
which is meant to replace the C++ library libical?
<br>
<br>
I think the Thunderbird Calendar needs fresh wind and a more
pro-active leadership.
