What in the serial number will tell me the year and week that a MacBook was built?

Thanks!
 
Serial number will be in the format 4H8123XXXXXXX

First 2 digits 4H are the factory - you can ignore them.

Next digit is the year - in this case 8

Next 2 digits are the week no - week 01 is January 1 (probably ISO standard) in this case week 12 - end of March.
