What is the Advent Calendar ad format?

Think of those chocolate advent calendars, but for your product — each day unlocks a new offer, sneak peek, or mini-surprise behind a numbered door or tile. Brands use this during holiday countdowns or product launches to build anticipation and keep people coming back, turning a single campaign into a multi-day ritual. It works best when you've got enough variety to sustain daily reveals and an audience eager enough to check in repeatedly.
