I like the doors! Great look :) How about putting them in a random order, like on a real Advent calendar?? (And, of course, this being Puzzling, maybe we should use a magic square - albeit with no 25: a central blank?) — Stiv Dec 1 at 8:25

(On a quick Google search, most — but certainly not all — of the pictures I see of physical Advent calendar do in fact have the numbers in order.)
