Is There Something Religious About This Kind of Advent Calendar?

I believe advent it's something to do with the religious aspect of Christmas. When I was a kid, I used to have an advent calendar which was very nice. It had like a religious scene on it, some Christian image on it. And then the last picture is always the baby Jesus, there he is. But this one I've got here is completely un-Christian. There's nothing religious about this this kinder advent calendar at all. No, it's it's just full of chocolate.
