Going beyond the usual functionality of fediverse servers, calendars have now been added to Epicyon. This is part of the effort to add features useful for organizing social events.

When creating a new post you can now optionally add a date, time and place description. The information gets attached to the post as a tag, using the ActivityStreams Event and Place activities.

There is now a calendar icon which then shows the current month.

Events posted by people you follow will show up there, and selecting particular days then gives you a list of events. If you just want to create reminders for your own use then you can send a DM to yourself containing a calendar event.

This makes organizing events very simple, and you can use message scopes to set up public or private events.

Users of Zot based networks will be yawning at this stage, because this sort of functionality has existed since Friendica, but as far as I know it's new within ActivityPub based systems.
