Sharp GF-767 Date Code

[MinerAC4]

I know this is probably going to be laughed at, but I always forget how you're supposed to read these. Can anyone help me figure out this date code in the back plastic of my 767?

 

[caution]

Pretty sure from left to right it's 1982, September 16th. Only having 0-3 as options for the third digit makes sense that it would be the first digit for the day of the month. Not sure about the fifth "1-4" digit, it could be a lot code for the mold or something.
