Did you know that in Denmark, learning English is basically a school subject for everyone? Since the 1970s, kids here have been learning it from elementary school, just like math or history! Because of that, if you visit Copenhagen, you'll hear both Danish and English almost everywhere you go.
And here's a cool language hack: Denmark is so close to Sweden that many Danes can understand a good amount of Swedish when they hear it (even if they can't speak it perfectly themselves). It's like having a built-in translator for your neighboring country!
Here's a cool money mystery for you! Most countries in Europe use the same currency, the euro, because they're in a big team called the European Union. Denmark is on that team, but they got a special pass to keep their own money!
So, instead of euros, everyone here pays with Danish kroner (DKK for short). It's like they have their own team jersey. And right now, one US dollar unlocks about six and a half Danish kroner. Pretty neat!
