filter by year only in date column

I'm trying to figure out how to filter by the year only in a column where I have dates specified as dd/mm/year.

This is being done through VBA and I tried the following (relevant code posted), but it doesn't seem to be working:

d_year = ComboBox2.Value
    If Not d_year = "" Then
                d_year = "*" & d_year & "*"
                With .Range("A1:K1")
                    .AutoFilter field:=6, Criteria1:=d_year
                End With
    End If

Any suggestions or help is appreciated.
