Your third axiom is incorrect. nivlac seems to understand the OP.
You have to understand Groundhogese. 
No. The opposite of GH day would be “Where the hell did my coffee go?” day after day after day after day after day after day after day after day…
Well, it’s your OP, so it can mean whatever you want it to mean. 
Murray’s character remembered each day even though it got reset. He didn’t age or die [permanently].
My problem is that my days (and weeks) sorta blend in to each other, with nothing memorable about them. (In other words, I don’t remember what I did last Tuesday at work.) My days don’t reset. I am not immortal, and I will die going “wha… so soon? I was just getting started!” 
It isn’t just going home and drinking coffee. It’s going home and drinking your 5475th cup of coffee. It’s going home and knowing that you’ll be drinking one cup of coffee like you have done every day for the past 15 years. Man!
Do you mean this:
In Groundhog Day the world started in the same state at 6:00 AM and Phil was a changed person from the day before. In your “opposite of Groundog Day”, the world is different each day, but Phil continues to do the same thing, day after day, no matter what. He’s at least trying to be the exact same person he was the day before.
?
OK…so, what’s the point?
Unless it is like having an amazing idea but you just can’t seem to find a way to explain it and every time you do try your audience just doesn’t get why this is such an awesome idea. And shit.
OK… I’m still not following Kozmik’s posts as all. But he said that **nivlac **understood what he’s been trying to say.
From nivlac’s post, it sounds to me like instead of Groundhog Day, in which a man keeps reliving the same day over and over against his will, Kozmik is suggesting a movie about a man who has the power to *intentionally *rewind the day to it’s beginning whenever he wants. It’s not something he can do at will, but it requires a specific trigger event; eg, finishing a cup of coffee, finishing the morning paper, or saying “Shazam!”
Am I close?
Eliza Dushku’s short-lived television series, Tru Calling, comes to mind. Although she didn’t exactly have control over the trigger event that caused her day to rewind.
This is actually addressed in the movie, when Bill asks one of the drunk guys (paraphrasing here), “What if you every day is exactly the same and you do the same thing day after day?” And the guy replies, “That pretty much sums it up for me.”
The OP has described pretty much the plot of every Philip K. Dick novel ever written.
Stranger
Yes.
Don Gorske is who I had in mind as the “opposite” of Phil Conners.
Don Gorske has eaten at least one Big Mac from McDonald’s every day since May 17, 1972:
OK but that whole thing where you were saying that the day doesn’t start till after someone eats their Big Mac/reads their paper doesn’t make sense. Stuff is still happening.
I never said that the day doesn’t start till after someone eats their Big Mac/reads their paper/drinks their coffee.
What’s the difference between the day starting and commencing?
What’s the difference between the day starting and ending?
the day starting: “I read my paper, I am on time at work, and I am ready *to begin **my *day.”
the day ending: “No time to read my paper, I got to be on time for work, I’ll read my paper after work, and *I will end **my *day.”
Wait, are you using the word “commence” to mean end? That might be why we’re having difficulties communicating.
Don’t fight the antithetical!
I’ll let the OP confirm (or, less likely, deny) this…but assuming it to be the case, allow me to hypothesize that the OP perhaps has long conflated the words “commence” and “consummate” (the latter does imply an ending of sorts). And/or, was misled by the noun “commencement”, which has come to be equated with “graduation”, which is definitely an ending…but what many of us forget is that the use of “commencement” in this context was meant to refer to the beginning of the rest of ones’s life, the beginning of one’s real-life career as a high school or college graduate.
Common mistake, I’d wager.
Yes, I wasn’t using the right words. I hope I can be understood now.
Quite so!
Well, the OP’s idea sounds a bit like Nicholson Baker’s book “The Fermata”, in which the narrator can stop time for everyone else pretty much at will, but do whatever he wants to while time is stopped.
Not quite the same, but perhaps along those lines. Especially in that the book is written, like Groundhog Day, with a kind of everyday-humor style that you don’t get from most sci-fi.
But in the OP you use these examples of someone saying that the president being shot/other events don’t matter until the coffee has been drunk which suggests that the day doesn’t begin until after that thing happens. But now you’re saying it doesn’t end until that thing happens?
I’m inclined to say the answer to the OP is no. You can’t experience the opposite of Groundhog Day. It’s like trying to find an opposite of “green.”
