As Christmas approaches, many people look forward to counting down the days until the big day with an Advent calendar. These calendars, filled with small treats or surprises, provide a fun and engaging way to mark the passing of time and build excitement for the festive season.
The joke "Why is it getting harder to buy Advent calendars? Their days are numbered!" plays on the dual meaning of the phrase "their days are numbered". On the one hand, it can refer to the fact that Advent calendars have a limited lifespan, lasting only from the beginning of Advent until Christmas Eve. On the other hand, it can also refer to the numbered doors on the calendar, each concealing a treat or surprise.
