Fuzzy math

I know math is not my stong suite but I think I can do basic math. So either the math is fuzzy or my memory is. You figure it out.
I heard over the weekend that the Thriller turned 25. I think there's a mistake because that means it came out in 1982 (2007-25=1982). I wasn't in Miami in '82 and I was in Miami when it came out. I saw the premier of the video on my first date when my now hubby that was in December 1983, I was 18. I know I was 18 when I moved to Miami so 1965+18=1983. Both hubby and I remember that we saw the premier at the club that we went to adn it makes sense, if it was a year old they would replay it around Halloween not Christmas. So, you figure it out...fuzzy math or faulty memory.
