Type: System.String A one-dimensional array of type String containing the culture-specific abbreviated names of the days of the week. The array for InvariantInfo contains "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", and "Sat".
If setting this property, the array must be one-dimensional and must have exactly seven elements.
If a custom format string includes the "ddd" format specifier, the DateTime.ToString or ToString method includes the appropriate member of the AbbreviatedDayNames array in place of the "ddd" in the result string.
This property is affected if the value of the Calendar property changes. If the selected Calendar does not support abbreviated day names, the array contains the full day names.
