The forum is supposed to be able to display an event in a calendar.
I’ve only found the following. Maybe it requires being in the Events subforum? In any case, you can at least do this. It is converted to the user’s local time:
2026-05-22T14:00:00Z→2026-05-22T15:00:00Z
In the toolbar, press + and then “Insert date / time”
Source:
[date-range from=2026-05-22T10:00:00 to=2026-05-22T11:00:00 timezone=EST5EDT]
(I don’t know if EST5EDT is equivalent to EDT, but it matches my expectation after conversion to my local time).
For what I mean for an event in a calendar, see Ada Monthly Meetup, 25th of April 2026
