:mrdocs:

Invalidate the calendar having the specified `calendarName` in this calendar cache, and remove it from the cache. If a calendar having `calendarName` is not present in this cache, this method has no effect. Return the number of calendars that were invalidated. Note that a calendar that has been invalidated in the cache remains valid to all outstanding references to it, obtained via earlier calls to the `getCalendar` and `lookupCalendar` methods, until all of those references have been destroyed.
