Tonight is "Sinterklaas", the night we Dutchies eat Speculaas, Pepernoten, Chocolate Letters & Schuimpjes, and exchange gifts.
Dutch Children don't believe in Santa, or the "Christmas Man" as we call him here. They believe in Sinterklaas, or Sint Nicolaas. You can probably tell from the name that he has the same origin as your Saint Nick. However, we don't believe he lives in Denmark, or on the Northpole, and he has nothing to do with Christmas.
We believe Sinterklaas lives in Spain, together with his helpers, the "Zwarte Pieten" (Black Petes). There are different stories on why they are black. Some say they used to be his slaves but he freed them and they were so thankful that they stayed with him, but the story I learned when I was little was that they are black because they go down the chimney to deliver the presents.
Every November Sinterklaas takes a trip to the Netherlands on his Steamboat. From then on, kids get to put their shoe in front of the fireplace, with a carrot & some hay for Sinterklaas' white horse. Zwarte Piet will go down the chimney, and replaces the carrot and the hay with a small present. Little did we know that we put the same carrot in our shoe every night ;)
December 5th (or December 6th in Belgium!) is Sinterklaas' birthday, this is when the big presents come! For Children anyway. Adults usually do a Secret Santa type thing, where the gift has to be accompanied by a rhyme, and often a self created something to hide the present in, I always loved making those things, and it was always fun to see what other people would make for you.
Happy Sinterklaas everyone!
