Please advise. Thanks.

I think you can forget that one. Date codes tend to be a manufacturer's "internal" code. A very common 4-digit date code format is WWYY where WW is the week from 01 to 52 and YY is the last two digits of the year. That means, a la DOS, we can't tell the difference in a cap made in 1905 and 2005!

Except that a cap made in 2005 is rarely made with a glass jar and two layers of foil, like we had when I was in school.

Also, some do a version of the "Julian Days" code, then convert to hex to reduce the number of digits.

I was going to add something similar to my post, but knowing Ron's always on the prowl, knew that I had to play the straight man at times.

Not to imply that Ron isn't straight ....
