Additionally, season 1 episode 2 "AKA Crush Syndrome" and season 1 episode 6 "AKA You're a Winner!" include flashbacks to a semi-recent event involving Kevin "Kilgrave" Thompson. Trish "Patsy" Walker refers to this when she says, "It's been a year, Jess."
2015 - 1 = 2014.
Season 1 episode 5 "AKA The Sandwich Saved Me", includes another flashback to an earlier point in the life of Jessica Jones .
Season 1 episode 11 "AKA I've Got the Blues" opens with an extended flashback to Jessica's adolescent trauma. Season 1 episode 12 "AKA Take a Bloody Number" shows a close-up of some medical documents pertaining to this accident presented by Dorothy Walker. The top of the document reads "STATEMENT DATE 04/13/00" surely representing April 13th, 2000 AD. The accident couldn't have been long before this hospital bill was made so the episode 11 flashback must take place in 2000 AD.
It is the third chronological TV show in the Marvel Cinematic Universe and can be watched at its timeline point or entirely separately.
