This Access tutorial explains how to use the Access Weekday function with syntax and examples.
The Microsoft Access Weekday function returns a number representing the day of the week (a number from 1 to 7) given a date value.
The syntax for the Microsoft Access Weekday function is:
Weekday ( date_value, [firstdayofweek] )
date_value is a valid date.
firstdayofweek is optional. It determines what day is to be the first day of the week. It can be any of the following values:
|vbUseSystem||0||Use the NLS API settings|
|vbSunday||1||Sunday (default used)|
If this parameter is omitted, the Weekday function assumes that the first day of the week is Sunday.
Please note that if you use the Weekday 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.
The Weekday function can be used in the following versions of Microsoft Access:
Weekday (#22/11/2003#) Result: 7 Weekday (#22/11/2003#, vbThursday) Result: 3 Weekday (#22/11/2003#, 5) Result: 3 Weekday (#01/01/1998#) Result: 5
The Weekday function can be used in VBA code in Microsoft Access. For example:
Dim LWeekday As Integer LWeekday = Weekday(#12/03/2001#, vbSunday)
In this example, the variable called LWeekday would now contain the value of 2.
You can also use the Weekday function in a query in Microsoft Access.
