Yes, they are defined by a span of years. An arbitrary span no one agrees on. Thus, Generation X not definitively 1965-1980 as you said. Even the U.S. government disagrees with that definition.
It's anything from the late 1920s to the mid 1980s depending on who you ask.
So you are saying it’s arbitrary and then in the very next sentence make the statement that it is defined as 1920 - 1980? Do you even know what you are trying to say at this point?
I’m reading just fine thank you. “Gen X is anything from 1965 to 1980.” What is the difference between that and what you said? Just the date range. It’s obvious this concept is just too much for your brain to handle or you are just being stubborn. No need to message me anymore.
Jesus Christ you are an idiot. Back to my original point, regardless of who you ask or what years are used to define it, a generation is literally defined by a range of years. You said, and I quote, “I'm amused with all the people who think there's some hard line where you have to be born before or after some exact year to be of a named generation.” What is so amusing about that? It’s the fucking definition you absolute brain dead fucking idiot. Shut the fuck up already.
