how can I match an day integer to AbbreviatedDayNames-CodePudding

I have the following function that return a list of the short day names in a week.

        public static string[] GetDayNames(string cultureCode)
    {
        var culture = CultureInfo.CreateSpecificCulture(cultureCode);
        string[] names = culture.DateTimeFormat.AbbreviatedDayNames;
        return names;
    }

I now need to match a specific dates day (integer value) to the correct AbbreviatedDayName, how can I do that?

The only way to do this is to convert the day into a date time and then to get the AbbreviatedDayName:

var ab = culture.DateTimeFormat.AbbreviatedDayNames[((int)dt.DayOfWeek)];

This is not possible. Not every 1^st of every month is the same day of the week. You need to observe the entire date (year, month and day) before you can take a stab at what day of the week it is.
