<p>How to set internationalization to a <code>DateTimepicker</code> or <code>Calendar WinForm</code> control in .Net when the desire culture is different to the one installed in the PC?</p>

For DateTimePicker
```
```
dtp.Format = DateTimePickerFormat.Custom;
dtp.CustomFormat = "yyyy-MM-dd"; // or the format you prefer
```
```
