You know that thing where you think back to the way you used to think? And you just can’t understand something about yourself? Like, there’s something you would have absolutely figured you would have cared about, and you cannot find any evidence that you did at all? Yeah, so I’m having one of those moments. Like, 1983 was the 400th full year since Pope Gregory’s reform of the calendar, so it was the first time that the modern calendar had experienced its full 400-year cycle. There is no way this wouldn’t be interesting to the young me, someone who still remembers where he was the day he heard Pluto had passed within the orbit of Neptune for the first time in 230 years. And yet … I have not the faintest memory of thinking of this fact at all in 1983. What’s going on there, you know? Seriously.
