When Does "John Wick" (2017) Take Place?
"John Wick" #1-#5 is a crime comic-book written by Greg Pak that released November 29th, 2017. So when is "John Wick" set?
It takes place on the fictional John Wick timeline roughly in the year:
We know this because at the beginning of the mini-series John Wick is not yet a professional assassin as he has become by the time of the feature film "John Wick" (2014), which takes place in 2014 AD. So it must be before 2014 AD.

~2006 AD
We know this because at the beginning of the mini-series John Wick is not yet a professional assassin as he has become by the time of the feature film "John Wick" (2014), which takes place in 2014 AD. So it must be before 2014 AD.
More specifically, Wick is shown using a cellular telephone with a color screen capable of text messaging in the second issue. Another flip-phone style cellphone with an extendable antenna is dropped in the same issue. Neither are candy-bar style cellphones like an iPhone smartphone, which first became available for purchase on June 29th, 2007 AD so it us most likely before mid-2007 AD. It could be as late as June of 2007 AD.
He is also shown in issue #1 buying a box of Cookie Crisp cereal with the mascot Chip the Wolf on it at an El Paso supermarket. Chip the Wolf became the new Cookie Crisp mascot in 2005 AD so it must be during or after 2005 AD. It could be as early as 2005 AD.
Unspecifcally, the main action of the story is only placed with the occasional free-floating that just says, "TODAY. EL PASO, TEXAS."
Additionally, there are multiple flashbacks depicting a traumatic moment in which Wick appears as an adolescent. At one point in the first issue, while referring to these events, Wick says, "Twelve years ago." This would place these explosive events in 1993 AD, 1994 AD, or 1995 AD.
2005 - 12 = 1993
or
2006 - 12 = 1994
or
2007 - 12 = 1995.
Furthermore, these flashbacks are labeled multiple times with relative time and place setting free-floating text as being "TWELVE YEARS EARLIER. EL SAUZEL, BAJA CALIFORNIA." or "MEXICO. TWELVE YEARS AGO."
It was collected as "John Wick: The Book of Rules".
