Minor tweak: the Emacs Calendar now shows only one timezone for in-person events. To mark that an event is in person, meetup organizers can add (in person) to the title of events that I syndicate from ICS feeds, or let me know if all of their events are in person so that I can make that the default setting for their feed. They can add (hybrid) or (virtual) to indicate other types of events. I can also create events manually. https://emacslife.com/calendar/
