References between worksheets are always absolute in Excel so you'll have to
edit the formula. You could use a macro to make entering the date formula
simpler though. For instance, select A1 on the new sheet and run this:

Sub EnterDate()
Dim ShtIdx As Integer
ShtIdx = ActiveSheet.Index
If ShtIdx 1 Then
With ActiveCell
.Formula = "=" & Worksheets(ShtIdx - 1).Range(.Address) _
.Address(False, False, , True) & "+7"
End With
End If
End Sub
