Parameters or Arguments
- number
- A value from 1 to 7, representing a day of the week.

Constant Value Explanation vbUseSystem 0 Use the NLS API settings vbSunday 1 Sunday (default used) vbMonday 2 Monday vbTuesday 3 Tuesday vbWednesday 4 Wednesday vbThursday 5 Thursday vbFriday 6 Friday vbSaturday 7 Saturday
Returns

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
The WeekdayName function can be used in the following versions of Microsoft Access:
- Access 2019, Access 2016, Access 2013, Access 2010, Access 2007, Access 2003, Access XP, Access 2000
Example
Let's look at how to use the WeekdayName function in MS Access:
WeekdayName (3) Result: 'Tuesday' WeekdayName (3, TRUE) Result: 'Tue' WeekdayName (3, TRUE, vbMonday) Result: 'Wed' WeekdayName (3, TRUE, 2) Result: 'Wed'
Example in VBA Code
The WeekdayName function can be used in VBA code in Microsoft Access.
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'.
Example in SQL/Queries
You can also use the WeekdayName function in a query in Microsoft Access.
For example:
In this query, we have used the WeekdayName function as follows:
Expr1: WeekdayName(3,True,2)
This query will return the abbreviated weekday name for the value 3, where the first day of the week is Monday (as specified by 2 as the final parameter). The results will be displayed in a column called Expr1. You can replace Expr1 with a column name that is more meaningful.
For example:
WeekdayValue: WeekdayName(3,True,2)
The results would now be displayed in a column called WeekdayValue.
