PowerPoint: Add Date of Yesterday and Tomorrow to a Slide

I want to have a table on my PowerPoint (2016) slide which should look like this:

To keep the slides intuitive, the dates should be updated automatically.

By using Insert -> Text -> Date & Time I can add a field containing the current date for the center column.

How do I add a dynamic field for yesterday and tomorrow?

First, follow the steps here to name your table. After that, insert a module (Alt+F11, Insert - Module) and add this piece of code:

Sub SetTableHeaders()
    
    Const SlideNo = 1
    Const TableName = "TableName Here"
    
    Dim MyTable As Table
    Set MyTable = ActivePresentation.Slides(SlideNo).Shapes(TableName).Table
    
    MyTable.Rows(1).Cells(1).Shape.TextFrame.TextRange.Text = Format(Now - 1, "yyyy-mm-dd")
    MyTable.Rows(1).Cells(2).Shape.TextFrame.TextRange.Text = Format(Now, "yyyy-mm-dd")
    MyTable.Rows(1).Cells(3).Shape.TextFrame.TextRange.Text = Format(Now + 1, "yyyy-mm-dd")
    
End Sub

Replace the SlideNo and TableName values with the right ones. Run it (F5) to set the headers.
