How can I incorporate the WorkDay function into my VBA code for calculating business days?

The WorkDay function is a useful tool in VBA that allows for the calculation of business days, taking into account weekends and holidays. To incorporate this function into your VBA code, you can use it in conjunction with other functions such as DateDiff or DateAdd to calculate the difference between two dates in terms of business days. This can be especially helpful in automating tasks that require the determination of business days, such as project timelines or employee leave requests. By utilizing the WorkDay function, you can ensure accuracy and efficiency in your VBA code for calculating business days.

Use WorkDay Function in VBA (With Example)


You can use the WorkDay method in VBA to add or subtract a specific number of working days to a date.

Here is one common way to use this method in practice:

Sub AddWorkDays()

Dim i As Integer

For i = 2 To 10
    Range("C" & i) = WorksheetFunction.WorkDay(Range("A" & i), Range("B" & i))
Next i

End Sub

This particular macro adds the number of working days specified in the range B2:B10 to each date in the range A2:A10 and displays the results in the range C2:C10.

The following example shows how to use this syntax in practice.

Example: How to Use WorkDay Function in VBA

Suppose we have a column of dates in Excel along with another column that specifies the number of working days to add to each date:

We can create the following macro to add the number of working days in column B to each corresponding date in column A:

Sub AddWorkDays()

Dim i As Integer

For i = 2 To 10
    Range("C" & i) = WorksheetFunction.WorkDay(Range("A" & i), Range("B" & i))
Next i

End Sub

When we run this macro, we receive the following output:

By default, column C displays the dates as serial numbers.

To instead display these values as recognizable dates, highlight the range C2:C10, then click the Insert tab along the top ribbon, then click the Number Format dropdown menu and click Short Date:

Each serial number will now be displayed as a date:

Note that if we specify a negative number in column B then the WorkDay method will subtract that number of working days from the date in column A.
