Summary
The Vatican City State (VA) liturgical calendar should be modeled as its own particular calendar derived from the General Roman Calendar — analogous to a national calendar — rather than being effectively equated with the General Roman Calendar (GRC).
Current behavior
VA appears in /calendars litcal_metadata.national_calendars (so it's already exposed as a national-style calendar, in la_VA).- However, in practice the Vatican calendar is currently treated as / aliased to the General Roman Calendar:
- In
CalendarSelect (standalone), selecting "Vatican" is treated the same as the empty option = General Roman Calendar (see Frontend CLAUDE.md).
- There is no distinct set of Vatican-proper liturgical events layered over the GRC.
This is not quite correct: the Vatican City State has its own proper calendar (its own particular celebrations / patrons / dedications) that should be derived from the GRC, not be identical to it.
Desired behavior
- Treat
VA as a genuine particular calendar that inherits from the General Roman Calendar and adds/overrides its own proper events, the same way a national calendar inherits from GRC (and a diocesan calendar inherits from its national calendar).
/calendar/nation/VA should return the Vatican-proper calendar (GRC + Vatican propriums), distinct from /calendar (pure GRC).- Anything that currently aliases "Vatican" → "General Roman Calendar" should be revisited so the two are no longer conflated.
Context
Surfaced while building the calendar-scoped permission UI in the Frontend (PR #354): VA is a valid national_calendar object_id (a nation with its own calendar), which highlighted that the underlying calendar for VA is currently just the GRC rather than a proper Vatican calendar.
Notes / open questions
- Source for Vatican-proper celebrations (propriums) to layer over the GRC.
- Locale handling (Vatican is inherently Latin
la_VA, but the proper calendar layer is separate from the locale question).
