finding manufacture date of a laptop

Was curious about the age of the machine I'm working on - a Macbook running Linux Mint. On MacOS, one can find details of the hardware by going to the About this Mac menu item from the Apple menu, copying the serial number and then checking sites like EveryMac.com or
https://serial-number-decoder.com/apple-serial-number/apple-serial.php

On linux, found that
dmidecode -t system
gives 

System Information

Version: 1.0
Serial Number: WxxxxxxYAGW
UUID: xxxxDA02-xxxxx-0A56-89AF-2ABCDxxxF

and that with the serial-number-decoder.com link above tells me 
"This 'MacBook Pro (15-inch, Mid 2010)' was made in Shanghai China in week 02 of 2011."
