Reading a code on a label

Food plants and depots often print the pack date as a Julian code, because it is short and sorts in order. A carton marked 27045 was packed on day 45 of 2027, February 14. A 4-digit code like 7045 drops the decade, so you have to know roughly when it was made. US egg cartons use just the three digits for the pack date.
