Note on the source name: The C# namespaces are still MoonBark.WorldTime.* and the csproj files still use the WorldTime name. The docs site is branded CalendarTime / MoonBark Calendar Time System as of 2026-06-02 (after two SEO reviews; calendartime won over calendar-time and timesystem). A source-level namespace rename (WorldTime.csproj → CalendarTime.csproj) is tracked as a downstream task.
