VBA Weekday

Excel VBA Weekday Function

Weekday in VBA is a date and time function which is used to identify the weekday of a given date provided it as an input, this function returns an integer value from 1 to 7 range, there is an optional argument provided to this function which is the first day of the week but if we do not provide the first day of the week then the function assumes Sunday as the first day of the week by default.

Can we tell the weekday number by looking at a particular date? Yes, we can tell the day number that week depending upon the starting day of the week. In regular worksheet functions, we have a function called WEEKDAY in excel to tell the number of the week for a particular date. In VBA too we have the same function to find the same thing.

What does Weekday Function do?

Weekday function returns the provided date’s day number in the week. For example, if you have dates 01^st April to 07^th April and if you want to know the day of the date 05^th April if the starting day of the week is from Monday it is the 5^th day.

To find this we have the same function “Weekday” in a worksheet as well as in VBA. Below is the syntax of the function.

Date: For which date we are trying to find the weekday. This should be a proper date with the correct format.

[First Day of Week]: In order to determine the weekday of the provided Date we need to mention what is the first day of the week. By default, VBA considers “Monday” as the starting day of the week. Apart from this, we can supply the below days as well.

Examples

Example #1

To start the proceedings let me start with a simple example first up. Now we will try to find the weekday for the date “10-April-2019”.

Step 1: Define the variable as String

Code:

Sub Weekday_Example1()

    Dim k As String

End Sub

Step 2: Assign value to the variable

Assign the value to the variable “k” by applying the WEEKDAY function.

Code:

Sub Weekday_Example1()

    Dim k As String

    k = Weekday(

End Sub

Step 3: Enter Date in Function

The date we are testing here is “10-Apr-2019”, so pass the date as “10-Apr-2019”.

Code:

Sub Weekday_Example1()

    Dim k As String

    k = Weekday("10-Apr-2019"

End Sub

Step 4: Show Value of Variable in MsgBox

By default, it takes the first day of the week as “Monday”, so ignore this part. Close the bracket. In the next line show the value of variable “k” in the VBA message box.

Code:

Sub Weekday_Example1()

    Dim k As String

    k = Weekday("10-Apr-2019")

    MsgBox k

End Sub

Ok, we are done.

If we run the code we will get the result as “4” because starting from Sunday the provided date (10-Apr-2019) falls on the 4^th day of the week.

Similarly, if you change the start day of the week it keeps varying. Below is an example line for the same.

Code:

k = Weekday("10-Apr-2019", vbMonday)

‘This returns 3

k = Weekday("10-Apr-2019", vbTuesday)

‘This returns 2

k = Weekday("10-Apr-2019", vbWednesday)

‘This returns 1

k = Weekday("10-Apr-2019", vbThursday)

‘This returns 7

k = Weekday("10-Apr-2019", vbFriday)

‘This returns 6

k = Weekday("10-Apr-2019", vbSaturday)

‘This returns 5

k = Weekday("10-Apr-2019", vbSunday)

‘This returns 4

Example #2 – Arrive Whether the Date is on Weekend or Not

Assume you have a date like the below and you want to find the next weekend date then we can use WEEKDAY function to arrive at the results.

We need to use WEEKDAY with IF condition and loops to arrive at the result. I have written the code for you to go line by line to get the logic.

Code:

Sub Weekend_Dates()

    Dim k As Integer

    For k = 2 To 9

        If Weekday(Cells(k, 1).Value, vbMonday) = 1 Then
             Cells(k, 2).Value = Cells(k, 1) + 5
        ElseIf Weekday(Cells(k, 1).Value, vbMonday) = 2 Then
             Cells(k, 2).Value = Cells(k, 1) + 4
        ElseIf Weekday(Cells(k, 1).Value, vbMonday) = 3 Then
             Cells(k, 2).Value = Cells(k, 1) + 3
        ElseIf Weekday(Cells(k, 1).Value, vbMonday) = 4 Then
             Cells(k, 2).Value = Cells(k, 1) + 2
        ElseIf Weekday(Cells(k, 1).Value, vbMonday) = 5 Then
             Cells(k, 2).Value = Cells(k, 1) + 1
        Else
             Cells(k, 2).Value = "This is actually the weekend Date"
        End If

    Next k

End Sub

This will arrive at the results below.

Look at the cells B6 & B7 we got the result as “This is actually the weekend date” because dates “04-May-2019” and “06-Apr-2019” are actually weekend dates, so no need of showing the weekend date for weekend dates. By default, we get the result as this.
