How do you read expiration code on grizzly tobacco can?

The last two digits of the code found on the bottom of the can.

For example; a code that reads S13AO2H2. The "H2" is the date.

The "H" represents the month and the "2" represents the year.

H2 would be August 2012

A=January

B=Feb

C=March

D=April

E=May

F=June

G=July

H=Aug

I=Sept

J=Oct

K=Nov

L=December

The letter "I' is skipped in the process. So, J=Sept, K=Oct, L=Nov, M=Dec.
