Mark,
I cannot get the formula right, sorry. I know this is wrong, but is this
close to how you write the formula?
=IFdate((C1),value)=true, then ((A1) value=1)

For i = 1 To 300
' The following condition checks for each cell

If IsDate(Cells(i, 2).Value) = True Then
Cells(i, 2).Offset(0, 4).Value = 1
End If
