## Calendar class


[Calendar](./) which defines how the dates are handled, calculated, formatted, etc. Setter operations are only enabled on non-read-only objects. Objects of this class should only be allocated using [System::MakeObject()](../../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../../system/smartptr/) pointer and use this pointer to pass it to functions as argument.

```cpp
class Calendar : public System::ICloneable
```
