How to use the WEEKDAYNAME Function (VBA)

Description

The Microsoft Excel WEEKDAYNAME function returns a string representing the day of the week given a number from 1 to 7.

Parameters or Arguments

Note

  • If you use the WEEKDAYNAME function in a query, you'll have to use the numeric value (ie: 0 to 7) for the firstdayofweek parameter. You can only use the constant equivalent (ie: vbSunday to vbSaturday) in VBA code.

Applies To

  • Excel 2016, Excel 2013, Excel 2011 for Mac, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000

Type of Function

  • VBA function (VBA)

Example (as VBA Function)

The WEEKDAYNAME function can only be used in VBA code in Microsoft Excel.
Let's look at some Excel WEEKDAYNAME function examples and explore how to use the WEEKDAYNAME function in Excel VBA code:
WeekdayName(3)
Result: 'Tuesday'

WeekdayName(3, TRUE)
Result: 'Tue'

WeekdayName(3, TRUE, vbMonday)
Result: 'Wed'

WeekdayName(3, TRUE, 2)
Result: 'Wed'
For example:
Dim LValue As String

LValue = WeekdayName(3, TRUE, vbMonday)
In this example, the variable called LValue would now contain the value of 'Wed'.
