Thanks Ralph. So if Oct 2004 is 01 then we should be good for deciphering dates until 99 months later which is still over 3 years from now. As long as Ilford don't change the coding system then we should be able to simply start again at 01 in 99 months from Oct 2004. Of course at that point there will be two "01s" but it is unlikely that retailers will still be selling Oct 2004 paper although some e-bay sellers might be! However a simple question such as: "Is this paper many years old?" will still determine which of two possible dates is the correct date.

You don't have to wait until then to have two '01s'. Ilford is using this system for decades! July 1996 was another '01'. As I said earlier, Kodak was using a similar system for paper. Agfa was using a completely different system. They just printed the use-by-date on the box, and saved us from all this hassle.
Keep in mind, this is the result of my attempt to decipher the code. I may be completely wrong. It's just my guess!
