Same. I also do this thing, where when I read about something that was some time ago with a specific year, I try to see it in the context of what I was doing back then, and what situation I was in. For example "ah, this was my last year of university, so I was living in that apartment, meeting so and so...". Again all those things are "free floating" with no feeling of calendar in my mind, but factually knowing what I was doing during some time frame and using other specific "anchor dates" of important events in my life and the world, it's fun to read about something old and reconstructing it in the context of my life back then. It does not work very well the other way around. There are a lot of memories similar to: "Oh, I remember that party... wonder when that was. I definitely was in university then, but that's not narrowing it down." (Especially because "pre-PhD" university studying lasted much longer in Germany back then than it is nowadays.) If I really wanted to know the exact year, it would be detective work.
