# CFCalendarCreateWithIdentifier(_:_:)

Returns a calendar object for the calendar identified by a calendar identifier.

```
func CFCalendarCreateWithIdentifier(_ allocator: CFAllocator!, _ identifier: CFCalendarIdentifier!) -> CFCalendar!
```

## Parameters

`allocator`

The allocator to use to allocate memory for the new object. Pass `NULL` or kCFAllocatorDefault to use the current default allocator.

`identifier`

A calendar identifier. Calendar identifier constants are given in [`CFLocale`](/documentation/CoreFoundation/CFLocale).

## Return Value

A calendar object for the calendar identified by `ident`. If the identifier is unknown (if, for example, it is either an unrecognized string, or the calendar is not supported by the current version of the operating system), returns `NULL`. Ownership follows the [The Create Rule](https://developer.apple.com/library/archive/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-103029).
