excel formula

[Guest]

6GN3839883
6G = NEVER CHANGES
N = MONTH 1-9 JAN - SEP, O - D OCT - DEC
3 = YEAR
39883 = IS UNIQUE TO THE PRODUCT
I WANT TO SET UP A FORMULA THAT WILL AUTOMATICALLY TELL ME IF THE PRODUCT IS
WITHIN WARRANTY.
IT CAN NOT BE ANY OLDER THAN 2 YEARS, I.E. 6GD901234 (6G DEC 1999) WOULD BE
TO OLD
SO IT HAS TO SHOW THAT IS WITHIN SAY 6G23????? AND 6G15?????.
I HAVE TRIED USING 'IF' BUT I CAN NOT SEEM TO GET THE FORMULA RIGHT.
IS THERE A FORMULA I CAN USE?

How would you display 1994, 2004 or 2009?
What I am meaning is how do you know (or how would excel know) 9 is 1999
and not 1909 or 2009? If there would be some system behind telling that
years greater than 4 is 1990 + the year and less than or equal is 2000 plus
the year, if so you can use something like

=IF(DATE(IF(--MID(A1,4,1)>4,MID(A1,4,1)+1990,MID(A1,4,1)+2000)+2,VLOOKUP(MID(A1,3,1),{"1",1;"2",2;"3",3;"4",4;"5",5;"6",6;"7",7;"8",8;"9",9;"O",10;"N",11;"D",12},2,0),1)<DATE(YEAR(TODAY()),MONTH(TODAY()),1),"No Warranty","Warranty")
