Workbook call duedate more than one sheet

Sorry that this must be a very simple code to put in but what syntax shall I put in for more than one sheet for workbook calling sheets for due date

This is what I have at the moment

Sub Workbook_Open()
    Call Sheet1.duedate
    
End Sub

I want to include Sheet2 and Sheet3 as well.
I've tried comma, bracket etc but did'nt work

Thank you

Private Sub Workbook_Open()
    Sheet1.duedate
    Sheet2.duedate
    Sheet3.duedate  
    ' ...
End Sub
