    Hi deanbland 

    I'm assuming you just have the month name in a column?  If so you can add a Custom Column and use Date.FromText to create a date.

    Here's a sample PBIX file.

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8krMK00sqlSK1YlWcktNKoJzfBOLkjPALMeCoswcqBhEzqs0LxXKyIGIOJamlxaXgJnBqQUlqblJqUVgnn9yST6M7ZdfhpBwSU2GcmIB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Months = _t]),
    #"Added Custom" = Table.AddColumn(Source, "Custom", each Date.FromText("1 " & [Months] & " 2020")),
    #"Changed Type" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", type date}})
in
    #"Changed Type"

     

     

    Regards
