A lot of countries also celebrate Three Wise Men day on January 6th to commemorate the Wise Men giving gifts to Baby Jesus and on the 5th you leave a box with grass for the camel to eat and something for the Wise Men to drink and on the 6th children receive presents that the Wise Men left.
My Dominican friend also says one of the wise men is a smoker and they leave cigs for him. Ok, not appropriate for kids but funny none-the-less.
Previously, at work, we celebrated x-mas around the world. I chose China and researched their tradition and brought in fortune cookies. It was a big hit.
