I think the easiest way to have 24/25 of something would be to have the "part 2" for each puzzle get released the next day. It would probably ruin the momentum about as much as having days off would (as another alternative to make the timing fit "advent"), but there could be a fun extra layer of puzzle with a hint of what the part 2 will be so people can try to speculate and modify their code in anticipation.
