WeekdayName Function |
Microsoft.VisualBasic.DateAndTime
WeekdayName( Weekday , [ abbreviate [, FirstDayOfWeekValue ]])
The ordinal number of the required weekday, from 1 to 7
Specifies whether to return the full day name or an abbreviation
Member of the FirstDayOfWeek enum indicating the first day of the week
A String
Returns the name of the day
Weekday must be a number between 1 and 7, or the function generates an ArgumentException error.
The default value of abbreviate is False .
For a list of the members of the FirstDayOfWeek enumeration, see the Weekday Function entry.
The default value of FirstDayOfWeekValue is FirstDayOfWeek.Monday.
Since Weekday is an integer, to determine the name of the day of a particular date, combine WeekDayName with a call to the WeekDay function, as the following code fragment shows:
sDay = WeekDayName(Weekday(dDate, iFirstDay), _ bFullName, iFirstDay)
Note that the value of the FirstDayOfWeek argument must be the same in the calls to both functions for WeekdayName to return an accurate result.
Unlike the Weekday function, the WeekdayName function behaves predictably. For example, if you ask for the name of the first day of the week when the week starts on Monday, the function returns Mon or Monday . If you ask for the fifth day of the week for a week that starts on Sunday, the function returns Thu or Thursday .
