Anyone wanted to arrange "generations" sensibly, in sliding window 5 & 10 year cohorts, would get my attention. There's some demographic value there.

This stupid crap inflicted on us, no. But:

I was born in '62. My cohort runs roughly '57-'67. I've got a lot in common with their experiences.

Someone born in 1980 had a lot in common with those born 75-85. And so on.

We have computers these days. This would be doable, if the poison of generational identification weren't so enjoyable.
