Answer 1

first two Solutions works fine but what if we would like to extend this to any culture so i came up with this approach i change the current culture date time arrays into TitleCase

private void SetDateTimeFormatNames()
        {

            Thread.CurrentThread.CurrentCulture.DateTimeFormat.DayNames = ConvertoToTitleCase(Thread.CurrentThread.CurrentCulture.DateTimeFormat.DayNames);
            Thread.CurrentThread.CurrentCulture.DateTimeFormat.MonthNames = ConvertoToTitleCase(Thread.CurrentThread.CurrentCulture.DateTimeFormat.MonthNames);

        }

private string[] ConvertoToTitleCase(string[] arrayToConvert)
            {
                for (int i = 0; i < arrayToConvert.Length; i++)
                {
                    arrayToConvert[i] = Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase(arrayToConvert[i]);
                }

                return arrayToConvert;
            }

how can this be improved with out the Loop?
