      If the calendar was written in C++ or many of it’s derivatives then signed integer overflow is undefined behaviour and it could technically choose to do anything it damn well wants (unsigned integers actually do have defined overflow behaviour). Something tells me the runtime of a paper calendar is anything but standard :D

      It’s not the overflow that’s the issue, but a calculation failure that causes the date value to be “0” and thus list the date as January 1, 1970. It’s happened to me several times with Pokemon GO.
