I’d agree. Born in 81 and don’t consider myself to be part of either generation. I’d group things more along the lines of 1960-1975, 1976-1985, 1985-2000, 2000->
But then we’d run out of alphabet letters.
I was born in 1980 (hence the 7-4-80), and I’ve seen the “XY Cusp” or “MTV Generation” used for those born between approximately 1975 and 1985.
