Change MonthCalendar Culture

Is it possible to change the date format of the MonthCalendar object of a WinForms application?

It happens that the culture selected on a client's station is Polish and this is causing an error in handling application dates.

I tried to use some alternatives like:

Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");

But I was not successful, the calendar retains the default date format (set in the OS Regional Settings).
