hi,

my guess, about what is wanted

function DayOfYear(DT : TDateTime) : Integer;
var dt1,dt2 : TDateTime;
    m,d,y    : Word;
begin
  dt1 := Trunc(DT);
  decodeDate(dt1,y,m,d);
  dt2 := encodeDate(y,1,1);
  Result := Trunc(dt1-dt2);  //maybe +1
end;

//sample to call
procedure TForm1.Button1Click(Sender: TObject);
begin
  edit1.text := inttostr(DayOfYear(DateTimePicker1.Date));
end;
