When Does "Terminator 2: Judgment Day" (1991) Take Place?
"Terminator 2: Judgment Day" is a science fiction film written by James Cameron with William Wisher that released July 3rd, 1991. So when is "Judgment Day" set?
It takes place in the year:
We know this because the computer screen in the police cruiser displays John Connor’s file and he's registered as born "2/28/85" (clearly meaning February 28th, 1985 AD) and he's listed as "AGE: 10".

1995 AD

1985 + 10 = 1995.
Additionally, there's a prologue labeled with a time and place setting title card as being "Los Angeles 2029A.D." so presumably, it's 2029 AD although this doesn't appear to be confirmable by context.
