Specifies the calendar name, a CFString object.

```
static let calendarName: CFDateFormatterKey!
```

## Discussion

With OS X version 10.3, [`gregorianCalendar`](/documentation/CoreFoundation/CFCalendarIdentifier/gregorianCalendar) is the only possible value. With OS X version 10.4, `kCFGregorianCalendar` and other calendar names are specified by CFLocale.
