We are in The Netherlands and we are seeing chocolate letters EVERYWHERE. Why? Because Sinterklaas (aka Santa Claus or Saint Nicholas) and his helper Zwarte Piet deliver them to you on the eve of Sinterklaas’ birthday – known as Pakjesavond! Here in The Netherlands, the Dutch celebrate the birth of Jesus on Christmas Day and the gift-giving and presents part of the holiday season is celebrated on Sinterklaas’ birthday instead – December 6th.
