September 18 is always a day I think of when it rolls around.
One time, in 1973, I was going through some of the work of moving us into an apartment, student housing somewhere.
I had to walk/run part of the way, because the housing office was some distance from the actual apartment complex. But it was right at the edge of town.
So there I was on that day. And I checked this out on a moon calendar place a few years ago just to verify it. The moon was up in the western sky. Why I remember that particular day, I don't know.
Every year as far as I can recall I think of this. There was something significant about that day ... and the moon.
