Automating UX Meeting time countdown or timezone or both in bbcode moinmoin with timeanddate.com or google calendar links like Frigde

Is countdown or exact timezone time more important if cant have one in other?https://wiki.ubuntu.com/Membership/Boardswritten The next 12:00 UTC meeting will be at Wednesday, December 21st, 2022 at 12:00:00 UTC on irc.libera.chat in #ubuntu-meeting.
Its not updated some time https://www.timeanddate.com/countdown/launch?iso=20220518T12&p0=1440&msg=12%3A00+UTC+Ubuntu+Membership+Meeting&font=slab&csz=1
In that link was old time Time until Wednesday, 18 May 2022, 12:00:00 (UTC time)
So i tried to calculate UTC in https://www.timeanddate.com/worldclock/meeting.html but there was no such thing as UTC.Maybe could be made new system?

Can some auto-calculating thing in wiki BBCODE counting down be made so i dont have to calculate and link would be auto made? And to check in my timezone this countdown? That would be priority to know my time to be on time, not to count days and hours down.

And we also have https://fridge.ubuntu.com/calendars/fridge/ where is all meetings in, so would it not be better to just link "Fridge"?

There is also link even more better- all calendars i just found, but new users will think timer is old so theres old info and will not be able to think that Frigde might mean time and calendar.
4 Calendars in one https://ubuntu-news.org/calendars/

If want can maybe make next event bbcode auto making with countdown text or link to timeanddate.com if we can get some code?
