In the continuing game of hiding production dates on BlueDef boxes they changed the date codes again. BlueDef and dealers do not want you to know if you are buying old DEF so they scramble the production date codes. Some time in the last few months it changed again. So far I cannot find a code cypher to translate the latest scramble of numbers. Anyone break the code?

Expires 12-21?? Only a guess. That'd be too easy, though.

The prior codes gave date of manufacture. Year was minus 1 and day was minus 360. And it started with a letter indicating factory where made.

The previous code was the year of expiration. Subtract 1 year from expiration for manufacture date. Then, the reverse Julian date, for cripe's sake. Maybe big brother spent some of our tax dollars to mandate a reasonable and across the market readable code?

With only a 1 year shelf life, the 12-21 sorta makes sense if you recently bought this box. I have emailed Old World Ind asking for the cypher code.

Edit to add response from PEAK tech support team:

So, it appears that they still use the same ridiculous reverse Julian date to keep everyone clueless. Apparently a new manufacture site or recoding to numerical from alphabetical added more confusion. I expressed my confusion and desire to have them change to a user friendly date code like Expires on: Dec 21 2021.

Maybe I missed an update. The old cypher I was working from was year of manufacture. They are clearly trying to hide the truth. Date of manufacture in hot climates is very important.
