postheadericon Julian Date Code

Julian date coding is a simple way to put the date code on a part.

  • Fewer characters
  • Sequential (for days of the year)
  • Smaller space required
  • Great for internal QC

Examples:

0203 for January 20, 2003. The code consists of Day Day Day Year

131C4 for May 11th, third shift, 2004. The code consists of Day Day Day Shift Year

26608 for September 23, 2008. The code consists of Day Day Day Year Year
