The only way I can have any accuracy about a pop culture event is if I can associate that event with a concrete event that happened in my life (and I remember the date of). It makes it fairly easy to remember events that happened when I was in school (what grade was I in? what year was I in that grade?) but harder for things since I have been working (where did I live/work? well that narrows it down to a few years).
What I’ve noticed is people who think that various 90s bands were from the 80s, or vice versa.
