I don’t know why I do it, exactly, but I started this five years ago and it’s just “something I do” now.
I buy the Farmer’s Almanac for the year.
It has zero practical necessity for me.
I get some kind of kick from it, a “how would you know these things with no internet or tv” vibe from it.
Each month gets the “various times” page above, and also a really quirky bit featuring old astronomical symbols.
So yeah, not at all useful, but still fun.
