Answer 1

You don't need to build your own culture. You only need to change the property DateTimeFormat.DayNames and DateTimeFormat.MonthNames in the current culture.

i.e.

        string[] newNames = { "Lunes", "Martes", "Miercoles", "Jueves", "Viernes", "Sabado", "Domingo" };
        Thread.CurrentThread.CurrentCulture.DateTimeFormat.DayNames = newNames;

However, it's weird that en-US show months and days with the first uppercase letter and for mx-ES not.

Hope it helps!.
