Example: FD930356731
The first and second numbers are for the Year 
The 3rd and 4th numbers are the week

Please Note! Decoding the year can be confusing. Take the first two numbers and add 20. Take the total and remove the 1st digit. This will be your date. 

FD 93 03 56731

93 +20=113 then remove the 1st digit. 

You are left with 13, so the date is 2013
