How do you read the code on Liggett and meyers cigarettes to figure out expiration date?

Look on the bottom or on the cap for example salad dressing and the first letter is the month second is the day and the last 4 digits unless ur like a million years old is the year. There's a difference between "best by" and "expired by" best by is when it will probably taste better and "expired by" it is no good anymore on that date like example "Expired/Best by 6/8/08 even though it's 2012
