Re: Looking for Excel Time Bomb to delete worksheet based on future date

Dear Excel Forum,
This is what I have on "ThisWorkbook"
As mentioned in my introduction the first two macro's work great.
Unfortunately, my third attempt at creating a Time Bomb macro based on a future date isn't working.
I get a Compile error: Ambiguous name detected: Workbook_Open
The File name is" Elbe Selector 2019

Private Sub workbook_beforeclose(Cancel As Boolean)
    Worksheets("Elbe").[B4,E4,E6,E7,E8,E10,E12,E14,E17,E19,E20,E22,E23,E25,E26,E27,E28,E29,E30,E50,E51,E93,E94,E95,I2,I3] = ""
    Worksheets("Companion Flanges").[D20,D22,D24,D26,D28] = ""
    Worksheets("Duty Cycle").[E12,E13,E14,E15,E16,E17,E18,E19,E20,E21,E22,G12,G13,G14,G15,G16,G17,G18,G19,G20,G21,G22,I11,I12,I13,I14,I15,I16,I17,I18,I19,I20,I21,I22] = ""
    Worksheets("Driveline Geomentry").[B3,B5,B7,B9,B11,B13,B14] = ""
   End Sub

Private Sub Workbook_Open()
Splashscreen.Show
End Sub

Private Sub Workbook_Open()
If Date < #8/1/2018# Then Exit Sub
With ThisWorkbook
.Saved = True
Kill .FullName
.Close False
End With
End Sub

Question: Is a Time Bomb option possible based on a date in the future?
I'm looking to delete my: "Elbe Selector 2019" spreadsheet each quarter based on a future calendar date.
I won't be needing a Read Only option. Just need to delete the entire file each quarter.
