At the end of Age of Ultron,

Tony Stark activates an AI named FRIDAY for the final battle in Sovokia against Ultron, as a replacement for JARVIS.

JARVIS is an acronym for for Just A Rather Very Intelligent System. What is FRIDAY an acronym for?

    Good question. Considering it's written as an acronym on the chip. I just figured we'd find out next Iron Man.

    @MichaelEdenfield It's from the novelization of IM1.

    ... "Yeti". I'm pretty sure the last word is "yeti".

    FYI: I don't think the mere name of something that appears in the movie is a spoiler, so I've tried to make the question more meaningful; if others disagree feel free to roll back.

I don’t think it stands for anything (yet). Here’s a picture of the disk; note that it doesn’t contain any periods:

enter image description here

There’s a minor character in the comics called “Friday” (Marvel Wikia), an AI that Tony develops as his “Girl Friday” AI to be his new assistant. He developed her rather than having to hire another human secretary. I think that’s what this disk is referring to.

Notice the disk labelled Jocasta? That’s the name of another AI from the comics (Marvel Wikia) built by Ultron so that he could have a mate, but just as Ultron’s comic origins were changed for the movie, so apparently were Jocasta’s.

Neither of these characters have names that correspond to acronyms in the comics. If they do stand for something, I don’t think it’s been revealed in the canon.

Edit: I went to see the film, and as Matthew Read correctly points out in comments, as he’s loading it on the screen, it definitely says “F.R.I.D.A.Y.”. I looked quite carefully for an expansion on screen, but I didn’t see anything. Sadface.

I did see that it’s labelled “Mark XLV (45) OS”. He’s using a Mark 43 when the film starts, so I don’t know what happened to the Mark 44. And that doesn’t tell us what FRIDAY stands for.

    To be fair, JARVIS is both an acronym and a reference to the comics character.

    @MichaelEdenfield I’ve seen suggestions that it says Tadashi (as in the Big Hero 6 character), but I haven’t found a screencap to confirm.

    It may be worth noting that "Girl Friday" is almost certainly a reference to Robinson Crusoe's manservant, Man Friday. May 6 '15 at 15:34

    In the movie, I recall IM's HUD showing F.R.I.D.A.Y. May 6 '15 at 16:35

It isn't an acronym, such as we know it. It is a nod to a comic artificial intelligence, Friday, Stark designed and used as a digital secretary.

enter image description here

Tony Stark decided there was no point in trying to hire a new secretary. Instead, he created his own “girl Friday” with a new A.I. program that would appear as a hologram of a young woman. Friday had a sweet, almost child-like disposition and was happy to show up whenever her boss needed her.

Friday grew up over time and Stark's interaction with her had become less frequent. She ultimately became a sort of adoptive daughter over time.

enter image description here

Stark has used other digital assistants in the past, all of them with acronyms for names. Friday is the only known exception.

  • H.O.M.E.R. (“Heuristically Operative Matrix Emulation Rostrum”):

  • P.L.A.T.O. (“Piezo-Electrical Logistic Analytical Tactical Operator”):

  • V.I.R.G.I.L. (“Virtual Integrated Rapidly-evolving Grid-based Intelligent Lifeform”) - from an alternative timeline

  • JOCASTA: Jocasta was, first, a person then became an enslaved artificial intelligence which helped Stark before regaining her body later.

    What's that quote from?

    Not a bad answer, except on-screen (as noted by alex in his edit), it definitely says F.R.I.D.A.Y. indicating it is an acronym in the MCU. May 15 '15 at 20:39

    Indicating lazy writers who wanted to tease viewers with an acronym for something that appeared in a comic book and calling it an Easter Egg. Acronym, not an acronym, not a big deal in the slightest. Someone could just as easily make one up and not have it confirmed one way or the other. I was not trying to make up an acronym, I was trying to explain the comic-related ORIGIN of it. May 15 '15 at 21:28
  • Note that the other chip which is fully visible in alexwlchan's still from the movie shows a blurry, but readable, JOCASTA.

It's not really an acronym for anything that I'm aware of. It just stands for, or represents the shortened version of the saying: My girl Friday, or gal Friday. It's a saying that represents an efficient and faithful female assistant. For example, "I'll have my girl Friday get the papers together." Although usually the saying is most commonly applied to a female, it can also represent a devoted male servant or assistant.

    Welcome to SFFSE! Do you have any evidence to back it up? As it stands, this answer doesn't really add anything to the answers already posted. Nov 20 '15 at 1:42
  • No, not really. It's just that Tony Stark addresses the AI in Avengers 2 as "My girl Friday." It could be an acronym for something, but as it stands I think it's just supposed to be a pun or play on the saying. I could be wrong.
