Production date in Serial Number

For new accessory products the production date is not always printed separately on the label.

For all accessory products containing a serial number you can find the production week by looking at the first 4 digits:

s/n: YYWWSSSXXXXXX
YY = year (08 for 2008)
WW = week (03 for week 3)
SSS = Supplier information
X = serial running number
