Format a range of columns based on their title - Excel - excel

Question

I've got part of a solution but it isn't working like I'd hope, so I've come to you for advice.
I regularly receive Excel files where I need to amend formatting. I'm trying to learn VBA by automating as much of these procedures as possible.
One particular format I complete is converting the date to "DDMMYYYY" (09091986), where it usually comes in as 09/09/1986.
Within my worksheet, there are a total of 3 columns containing dates, all of which need the same formatting and all of which have the word "DATE" in the heading. They are not adjacent to each other.
I must also be careful not to have any other data affected, as I have names and addresses which may contain the characters "DATE".
So, background out of the way... I'm trying to search the first row until I find the word "Date" and then format that for each cell until the last row, before moving on to the next column containing the word "DATE" and repeating this until all columns with the word "DATE" have been formatted.
I'm sure you have a simple solution but I can't seem to find it myself.
Here is the code I have...
Sub Dateformat()
Dim LastRow As Integer
Dim FindCol As Integer
Dim C1 As Integer
LastRow = Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
FindCol = Cells.Find(What:="DATE", LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, SearchFormat:=False).Column
For C1 = 2 To LastRow
Cells(C1, FindCol).NumberFormat = "DDMMYYYY"
Next C1
End Sub
This works for the first column containing date but doesn't move on to the next column.
Thanks for the help

As you know, you need to loop through and find each Row Header with DATE
Here is one way to do it.
Sub Dateformat()
Dim wks As Worksheet
Dim LastRow As Integer
Dim FindCol As Range
Dim sAdd As String
Set wks = ThisWorkbook.Sheets("Sheet1") ' adjust as needed
With wks
LastRow = .Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
'find first instance where DATE exists in row 1 (headers)
Set FindCol = .Rows(1).Find(What:="DATE", LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False, SearchFormat:=False)
'store address of first found instance (to check in loop)
sAdd = FindCol.Address
Do
'format column (row 2 to last used row)
.Range(.Cells(2, FindCol.Column), .Cells(LastRow, FindCol.Column)).NumberFormat = "DDMMYYYY"
'this line works as well and is a bit cleaner
'.Cells(2, FindCol.Column).Resize(LastRow - 1, 1).NumberFormat = "DDMMYYYY"
'find next instance (begin search after current instance found)
Set FindCol = .Cells.FindNext(After:=FindCol)
'keep going until nothing is found or the loop finds the first address again (in which case the code can stop)
Loop Until FindCol Is Nothing Or FindCol.Address = sAdd
End With
End Sub
