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 "2/28/85" representing February 28th, 1985 AD next to "DOB" representing date of birth and he's listed as "AGE: 10".

1995 AD
We know this because the computer screen in the police cruiser displays John Connor’s file and he's registered as "2/28/85" representing February 28th, 1985 AD next to "DOB" representing date of birth and he's listed as "AGE: 10".
1,985 + 10 = 1,995.
Additionally, there's a prologue presenting the horrors of the world after Judgement Day. Sarah Connor's psychiatrist Doctor Peter Silberman says, "The year ah... 2029, if I remember correctly." Though he considers Sarah’s future knowledge to be delusions. Furthermore, it's labeled with a time and place setting title card as being "LOS ANGELES 2029A.D." so presumably, it is 2029 AD.
It is the second chronological film in the Terminator universe and can be watched at its timeline point.
