  • After that, type the following code:
Sub overdue_days()

Dim cell As Integer
Dim J As Integer
Dim due_date As Date

due_date = #1/11/2022#

For cell = 5 To 11
If Cells(cell, 4).Value = due_date Then
 Cells(cell, 5).Value = "Submitted Today"
  ElseIf Cells(cell, 4).Value > due_date Then
  J  = due_date - Cells(cell, 4).Value
   J = Abs(J)
   Cells(cell, 5).Value = J & " Overdue Days"

💬 Things to Remember

VBA Date function actually works like the TODAY function in Excel.

VBA DATE is a non-volatile function in excel. That means it will retain the data even there is a break in the power supply.

Basically, VBA saves Date values as DATE at the time of implementation.

So, if you try to assign a date variable as a string/text, it will cause an error.

The default value of Date is 0:00:00 (midnight) on January 1, 0001.
