When Does "Looper" (2012) Take Place?
"Looper" is a science fiction film written by Rian Johnson that released September 28th, 2012. So when is "Looper" set?
It takes place in the year:
We know this because there's a string of identifying numbers Joe brings back from the future reading: "07153902935" that Sara marks off with a pen in two places while saying, "This is Cid's birthday and this is the med code of the hospital he was born in." So Cid was born on "07 / 15 / 39" representing July 15th, 2039 AD and he appears to be somewhere between 4 and 7 years old. So it has to be after 2043 AD and before 2046 AD.

2044 AD
2,039 + 4 = 2,043
to
2,039 + 7 = 2,046.
[HOWEVER, when Jesse (the gangster pretending to be a cop) asks "How old?", Sara responds that Sid is "10". He reiterates, "10, you said? Your boy?" Though her body language strongly indicates she doesn't trust Jesse from her very first interaction with him and almost certainly is lying. If she's not, the current year would be 2049 AD and it is sometime after July.
2,039 + 10 = 2,049.]
More specifically, the first scene includes a time and place setting title card over the footage reading "KANSAS 2044" though there's no way to confirm with via context.
There's also two short but key portions of the story that take place 30 years later after a series of title cards track the main character’s trajectory from "YEAR 1" to "YEAR 30", which brings the audience to 2074 AD [or possibly 2079 AD].
2,044 + 30 = 2,074
[or
2,049 + 30 = 2,079].
