Thought I would ask the experts! 12B 080 357 4HS07 142029 11L 11U 19A 11B I hope I understand all of it but I've been told that the "080" is the "Day of Production". I know 12B is the second week of December. Do the production days start the third week of August? You count every week day and subtract holidays to get the total 80? I think that is correct I just want confirmation. I know the rest. Thanks, Brian
