Just as the USA has Halloween, we have it too. Only in Danish it is called "Fastelavn" or a closer word would be Carnival. In a religious case, it is the day/evening before the feast started. It is nowadays (and have been for many years back) been celebrated as a child's day where they dress up, and instead of doing trick or treat they will take a bat and hit on this barrel which has candy inside it. These barrels were mostly for older children. For the smaller ones, it is all about dressing up and have a good time.
It's also a celebration of the time between winter and spring, though not that many people think about it on the day itself. I didn't think about it till I was older. Looking back, I haven't tried a day like this with deaf/hard of hearing people/friends, so I can't tell of my experience on that side. I can tell for me it was a bit confusing when I was in Kindergarden, as there were many all lined up waiting to hit the barrel and it went so fast at times. It was hard to see or hear who became "cat" king or queen. ("cat" queen hits open the top of the barrel, "cat" king hits open the end of the barrel - it is called cat, as there is a cat painted on the barrel).
