How can I read coded dates on food packages?

According to the University of Nebraska, numbers one through nine may indicate the months January to September, while the letters O, N and D represent October, November and December, respectively. When only letters are used to denote months, letters A through L are used to indicate the January through December.

Years are numbered based on the last two integers of a given year. One stands for 2001 while 14 stands for 2014. The date may be mentioned as the day of a given month and labeled with numbers one through 31, or as the day of a given year, and denoted by the numbers 1 through 365, according to Newsday.
