Need vba function to fix dates in a field

go to the textfield's Format property and format accordingly. We probably no need to use Format function in this case (if that field is bounded to the source that's a risk we may also changed its original value).

MS ACCESS 2003: DEFINE A CUSTOM FORMAT FOR A DATE/TIME FIELD ON A FORM
http://www.techonthenet.com/access/forms/format_date.php

I do not have a form. So I need to loop through the table and fix any dates that are not in the format I need.

this worked... based on  kelvin:
Public Sub FixDate()


Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT [Date Hired], [birthdate] FROM [Employees Information2]")

'Check to see if the recordset actually contains rows
If Not (rs.EOF And rs.BOF) Then
    rs.MoveFirst 'Unnecessary in this case, but still a good habit
    Do Until rs.EOF = True
        'Perform an edit
        rs.Edit
        rs![Date Hired] = Format(rs.Fields("Date Hired"), "mm/dd/yyyy")
        rs![BirthDate] = Format(rs.Fields("Birthdate"), "mm/dd/") & "2015"
        'rs("VendorYN") = True 'The other way to refer to a field
        rs.Update

        'Example Save contact name into a variable
        'sContactName = rs!FirstName & " " & rs!LastName

        'Move to the next record. Don't ever forget to do this.
        rs.MoveNext
    Loop
Else
    MsgBox "There are no records in the recordset."
End If

MsgBox "Finished looping through records."

rs.Close 'Close the recordset
Set rs = Nothing 'Clean up
End Sub

Thanks !
