Dior date codes and authenticity cards

Oh wow haha I thought I got it all figured out. Do you mind sharing how the system work (no worries if you dont)? I just assumed the first 2 digits means the year it was made.
1126 is looked at this way: 12 and 16 (first and third digit, and then second and fourth digit). 12 is the month of production (December), and 16 is the year (2016).
