Mattel Hot Wheels Date (base) Codes

Starting in 2008, Mattel introduced a manufacture date code on the bottom of Hot Wheels and Matchbox - refer to as the Base Code. The first character is a letter that represents the year and the numbers which represent which week of the year the car was manufactured.

For example, if you have a base code that reads "B30", that is a casting from the 30th week of 2009. A base code reading "P41" is a casting from the 41th week of 2021 (the week of October 10, 2021). Letter "I", "O", & "Q" are not used.
