There's a fairly easy way to derive the manufacture date if you happen to know the serial number. The serial number will be in the format: ‘LLLYYWWSSSS’; where ‘YY’ is the year of manufacture and ‘WW’ is the week of manufacture. The date code can be found in the 4 middle digits of the serial number. In the case of serial number SAD08300D4W, ‘08’ is the year code and ‘30’ is the week code. You can then decode the date use the following: Here are the Manufacturing Year Codes: 01 = 1997 06 = 2002 11 = 2007 16 = 2012 02 = 1998 07 = 2003 12 = 2008 17 = 2013 03 = 1999 08 = 2004 13 = 2009 18 = 2014 04 = 2000 09 = 2005 14 = 2010 19 = 2015 05 = 2001 10 = 2006 15 = 2011 20 = 2016 And here are the Manufacturing Week Codes: 1-5 : January 15-18 : April 28-31 : July 41-44 : October 6-9 : February 19-22 : May 32-35 : August 45-48 : November 10-14 : March 23-27 : June 36-40 : September 49-52 : December I hope this helps.
