Finding month of manufacture

[INNAWE]

JUST TRYING TO PURCHASE A FEW THINGS FOR MY 1992 VP V8 CALAIS AND HAVE BEEN ASKED WHAT MONTH THE CAR WAS MANUFACTURED.
NOW CAN ANYONE PLEASE TELL ME HOW TO FIND THIS INFO IF THE CAR WAS BOUGHT UNREGESTED AND NO CAR MANUAL.
IS THE INFORMATION HIDDEN WITH IN THE VIN NUMBER?

ANY HELP WOULD BE GREATLY APPRECIATED.

CHEERS

SORRY GUYS FORGET ABOUT IT ALL. JUST REMEBERED IT IS ON THE PLATE IN THE ENGINE BAY. JUST HAD A BRAIN FADE LOL
