 In VB.Net it is
Try     Date(2018,13,1)
If Error Resume Next
This will tell it to resume at the next error without taking any other action.

 I can not understand what you want to get.
Now also .net uses Try, Catch and Finally.
If you want to continue after the error set just try:
Try something
Try something else
if you want to stop set:
Try something
if error then return
Otherwise read here:

In particular:
Public Sub Main()
  
  Dim x As Date
  
  Try x = Date(2018, 13, 1)
  If Error Then
    Print "Month max 12"
  Else
    Print "Exit"
    Return
  Endif
  
End

BUT IS:

Try If Date(2018,13,1) then stop
