If you need to generate random dates in Excel, this post will show you how to do it using a formula and a VBA code. While there is a built-in formula for generating random numbers in Excel, there is no direct formula for generating random dates.
However, you can create a user-defined function in VBA that will generate a random date between two given dates. Or you can also use a combination with RANDBEWEEN and DATE functions to generate random date in Excel.

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 Randomize 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:
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.
