2. Generate Random Date in Excel using User Defined Function with VBA Code

You can generate a random date in excel using a User defined function with VBA code. Just do the following steps:

Step1: Press ALT + F11 to open the Visual Basic Editor (VBE).

Step2: In the VBE, go to “Insert” > “Module” to create a new module.

Step3: Copy and paste the following VBA code into the new module. Save the module and close the VBE.

Function RandomDate_ExcelHow(startDate As Date, endDate As Date) As Date
    RandomDate_ExcelHow = Int((endDate - startDate + 1) * Rnd + startDate)
End Function

Step4: Go back to your Excel workbook and select the cell where you want to use the user-defined function. Enter the following formula in a blank cell:

=RandomDate(DATE(2022,1,1), DATE(2022,12,31))

Where “DATE(2022,1,1)” and ” DATE(2022,12,31)” are the dates between which you want to generate a random date.

Step5: Press ENTER to generate the random date.
