If you’re near the cusp, pick whichever makes you feel better. Generations are a sociological construct and are appropriately applied in the aggregate, not to individuals and they’re always fuzzy around the edges. Much like Hari Seldon can’t predict specific individual events, sociological generations don’t always apply exactly the same to individual people.
If you’re born anywhere between around 1978 and 1984, you will likely find at least one sociologist who draws the line on either side of you.
I tend to go with Strauss-Howe, who consider GenX to be 1961-1981 and Millennials to be 1982-2005 – mostly because I like their idea of turnings and cyclical archetypes.
You think that’s absurd? Have you never gotten married? Wedding photos are extremely important and while “she almost vomited” may be hyperbole, I can definitely understand being very pissed off if that was the only version of the photo. Our wedding photographer whitened our teeth in our photos and we requested that they undo that so we look like ourselves. The sentiment was nice, but we didn’t want that. I would have been pretty unhappy if they hadn’t held onto the originals and were unable to revert our teeth back to their normal shades. Photos of our bridal showers and dress hunting were nearly as important as the wedding photos themselves. I can understand being upset with this undesired result.
