When Does the Second TV Show "The Flash" Season One (2014) Take Place?
"The Flash" season one is a science fiction superhero television show showran by Andrew Kreisberg [adapting "Showcase" #4 (1956) by Robert Kanigher as well as "The Flash: Rebirth" # () by Geoff Johns] and released October 7th, 2014.
It takes place on an alternate timeline of the fictional DC Films Universe in the years:
We know this because in season 1 episode 10 "Revenge of the Rogues", Caitlin Snow attempts to solve the mystery of what happened to Ronnie Raymond by searching in a database of some kind for the word "Firestorm" and among the results is an entry for "FIRESTORM Movie (2011) - Direct-to-DVD Release" and "3 Years Ago" below it.
2014 AD - 2015 AD
2011 + 3 = 2014.
Additionally, season 1 episode 1 "Pilot" (2014) starts with the incident which turns Barry Allen into The Flash just a fifth in but includes a title card very early afterward that reads "9 MONTHS LATER". So season 1 episode 1's beginning takes place almost a year before the rest of the episode and the rest of the season, in either late 2013 AD or early 2014 AD.
There are also three flashbacks in season 1 episode 11 "The Sound and the Fury" (2015) labeled "2 YEARS AGO" so they probably take place in early 2013 AD. Since the episode's main action is after season 1 episode 9 "The Man in the Yellow Suit" (2014) (which depicts the characters enjoying Christmas in December of 2014 AD), the season takes place over more than one calendar year, into early 2015 AD.
Finally, in season 1 episode 21 "Grodd Lives" (2015) Barry refers to the time since he became The Flash as "this past year" and in season 1 episode 23 "Fast Enough" (2015) Detective Joe West also says, "this past year" just after saying the phrase "why you became the Flash", conclusively showing the story takes place over more than 1 full year from early 2013 AD or 2014 AD to early 2015 AD. In season 2 episode 1 "The Man Who Saved Central City", an issue of "Central City Picture News" is shown with a front page describing the very previous scene and is dated for "WEDNESDAY, OCTOBER 7, 2015" but these final episodes' events are twice said to be "6 months" in the past. Specifically, it's April of 2015 AD at the conclusion of the first season.
10.2015 - 6 months = 4.2015.
MANY episodes also include flashbacks to Barry's childhood in March of 2000 AD. This can be so specific because the key date is mentioned in season 2 episode 1 "The Man Who Saved Central City" as "on the night of March 18th in the year 2000". The fateful day the viewers see over and over again first in season 1 episode 1 "Pilot" also opens as a prologue that includes a time setting title card reading: "14 YEARS AGO".
2014 - 14 = 2000.
In the second half of the season, these title cards change to "15 YEARS AGO".
2015 - 15 = 2000.
It is an early chronological TV show in the DC Films multiverse timeline (a first chronological show to feature Barry Allen/the Flash) and can be watched either at its timeline point, before "Justice League" (2017) as an extended flashback, or (mostly) separately.
