all these "years" and "months" and "dates" are just time systems for old people, I now declare that all human events be categorized in terms of series/season/episode

but I'm stuck bc you could have

s1: holocene era
s2: ancient era
s3: postclassical
s4: modern

or even then you've got

Humans: Modern Era
s1: renaissance
s2: late modern
s3: contemporary

alternatively:

humans s2021e01: Bean Dad

i mean we're talking about badly plotted episodes + seasons + arcs we may as well go all-in
