This mainly
applies to Ford Motor Company vehicles. Thanks to Bob Goodson and
friends for the research and sharing.
The Date Code, not
part of or to be confused with a
Service Part Number or "Casting Number", is arranged in a ymd or ymdd
fashion. Deciphering the year and day is straightforward but deciphering the
month can be confusing.
A letter corresponds with a month so A = January, B = February, C = March and so
on. Now comes the confusing part...
The researcher - Bob Goodson, adds, "Count the numeric position of the letter
J (10) and it's corresponding month (October). So J = October, right? Not
exactly; J = September. Why? FoMoCo does not use I or O in Date Codes. The
reason for that is so I will not be confused with 1 and O will not be confused
with 0."
