Remarks
The LongDatePattern property defines the culture-specific format of date strings that are returned by calls to the DateTime..::..ToString and DateTimeOffset.ToString methods and by composite format strings that are supplied the "D" standard format string.
See Custom Date and Time Format Strings for individual custom format specifiers that can be combined to construct custom format strings such as "dddd, dd MMMM yyyy".
You should set the date separator in the long date pattern to an exact string instead of using the date separator placeholder. For example, to obtain the pattern MM-DD-yyyy, set the long date pattern to "MM-DD-yyyy".
