How should I interpret this expiry date? I have a just opened plastic 4L container of cranberry juice that I bought several months ago. The expiry date on the container is 14 DE 15. I don't know if that should be interpreted as 14 Dec 2015, or 15 Dec 2014.

In general I have this problem with many expiry dates and am curious if there is any kind of standard.
According to this government website from Canada, the date on your product should be read as 15th of December of 2014.
