      featuring such gems as “An ISO week-numbering year has 52 or 53 full weeks. That is 364 or 371 days instead of the usual 365 or 366 days.”

   It seems cursed, but not sure there's another way. 365 isn't divisible by 7 so either you have weird week numbering, or you have a week that lasts 1-2 days depending if leap year or not. Pick your poison 😅

         Haha yeah that would certainly simplify things. While we're at it, get rid of timezones too.
