(looking for a shortcut to here?: balug.org/covid will, at least for the time being suffice, as will https://www.balug.org/covid-19, etc.)
Due to COVID-19/SARS-CoV-2,
effective 2020-03-17, San Francisco Bay Area [Linux] User Groups ([L]UGs) have suspended in-person meetings, at least for the time being / until further notice (including BALUG) - see also the immediately below.
2021-04-10 Some in-person meetings starting to resume … initial ones may just be private or by private invitation, continuing to (more) public - at one's own risk/discretion and may be with various restrictions, etc. Presumably at/after some time, these will resume (more-or-less) "normal" in-person meetings, though virtual may also continue. Note also that some venues remain closed (e.g. some businesses didn't survive COVID-19), so always advised but especially so, to check relevant current website/list information for the group regarding meeting location(s) and status and such.

Note that some [L]UGs are conducting virtual meetings.
This is not necessarily a fully updated comprehensive list, but this is list of at least (some)
San Francisco Bay Area [L]UGs known to be having / having started conducting virtual meetings. In general see the LUG[s] Web site and/or list(s) for the most current information:

Please see also: meta-list_-_list_of_lists - note that many [L]UGs may have rather to quite active list(s), even if they're not currently meeting - and/or may have relevant updates and information, etc. on their Web sites.

Absolutely by no means a complete list, but here are some LUGs that have started having on-line / virtual meetings:

On any system with GNU date(1), included in GNU coreutils, you can convert a remote event's time/date to your local timezone's time/date using syntax as per the following example:

$ date -d 'TZ="Europe/London" 2021-02-13 14:00'
Sat Feb 13 06:00:00 PST 2021
$

GNU date(1) will use your system's TZ database to convert time/date correctly, including compensating for DST / Standard Time issues at either your and/or the remote location.

It is also possible to generalize that syntax, to convert to a timezone differing from your local timezone, by prefacing the foregoing command with an output-timezone qualifier, e.g., as follows requesting conversion to Arizona time/date:

$ TZ='America/Phoenix' date -d 'TZ="Europe/London" 2021-02-13 14:00'
Sat Feb 13 07:00:00 MST 2021
$

Quoting must be as shown, and timezone names must be correct, or you will get errors or (worse) silent ignoring of the provided timezone qualifier. Use canonical TZ database names. Do not use familiar 3- or 4-letter shortcut names like PST and PDT, as they are neither unique nor standardised – nor UTC offsets like UTC-8, which for many locations have DST vs. Standard Time problems: The short names' ambiguities become more troubling the more international one's focus is. For example, "CST" can mean either China Standard Time (UTC+8), Cuba Standard Time (UTC−5), or (North American) Central Standard Time (UTC−6), and it is also a variant name for ACST (Australian Central Standard Time, UTC+9:30). Likewise, a time zone's short name will differ depending on language, as with WET (Western European Time, UTC+0), also known as WEZ (Westeuropäische Zeit) in German, HEO (Heure d'Europe occidentale) in French, ZEČ (Západoevropský čas) in Czech, and ΏΔΕ (Ώρα Δυτικής Ευρώπης) in Greek. Thus the short names' deprecated status.

(As people have asked: No, BSD date(1), as available on MacOS, cannot do this work, for lack of the -d option.)

However, "homebrew" to the rescue: If you install homebrew on your Mac and run "brew install coreutils" to install the GNU coreutils, then GNU date will become available as binary executable "gdate" (as will many other fine GNU enhancements).

On Microsoft Windows, install GnuWin, to acquire GNU coreutils and thus its "date" utility.

If you would rather use a WebUI, outsourced tools exist.
