Parameters

Weekday
Type: System.Int32
Required. Integer. The numeric designation for the weekday, from 1 through 7; 1 indicates the first day of the week and 7 indicates the last day of the week. The identities of the first and last days depend on the setting of FirstDayOfWeekValue.
Abbreviate
Type: System.Boolean
Optional. Boolean value that indicates if the weekday name is to be abbreviated. If omitted, the default is False, which means the weekday name is not abbreviated.
FirstDayOfWeekValue
Type: Microsoft.VisualBasic.FirstDayOfWeek
Optional. A value chosen from the FirstDayOfWeek enumeration that specifies the first day of the week. If not specified, FirstDayOfWeek.System is used.

Return Value

Type: System.String
Returns a String value containing the name of the specified weekday.

The string returned by WeekdayName depends not only on the input arguments, but also on the Regional Options settings specified in the Windows Control Panel.

NoteNote:

WeekdayName uses the current calendar setting from the CurrentCulture property of the CultureInfo class in the System.Globalization namespace. The default CurrentCulture values are determined by Control Panel settings.

The FirstDayOfWeekValue argument can have one of the following settings.
