No. Actually Pope Gregory XIII introduced the calendar in the 1500s. I wasn't born until the 1950s.


He was one smart Pontiff, figuring out tire date codes back then. :B
Mike. Comments are anecdotal or personal opinions, and worth what you paid for them.

"Date codes differ from mfg to mfg but the info above could be correct."

Beg to differ, sir. A portion of the DOT required alpha-numeric string can
be used by the tire manufacturer for his unique coding, however the last 4 digits must, by DOT rules for every tire requiring DOT marking sold in the USA, indicate week and year tire was manufactured.
