Wow that's interesting. We have a similar tradition (latin america and spain...I don't know if there's more)
We set out our shoes (kids I mean), on the night of January 5th so the 3 Wise Kings would leave presents. We also leave water and grass for the Camels!
Do you do that in the Netherlands or rest of Europe too?
We just leave a red sock over the fireplace, if there is a fireplace, otherwise under the tree, so that Santa Claus leaves the presents there... My parents used to put my present on the balcony early morning of New Year's Day and told me Santa Claus had left it...
Santa Claus brings the presents in New Year's Day for us... Well come to think of it, St Nicolaus (his name is celebrated in 6th of December) is not the Santa Claus for us (although in the scibes he is known as a secret gift giver, such as coins in shoes etc, to the deprived ones...)...but rather, Saint Basil of Caesarea is our Santa Claus... His name day is celedrated on the 1st of January and this day is mostly associated with giving gifts in Greece, because Saint Basil was known for helping the poor, hungry and unfortunate...he also donated his whole property, once he became a Bishop, to the poor and founded various institutions for them...
But there is also another reason why we consider him more as a gift giver rather than Saint Nicolaus...when Saint Basil, back in the fourth century, was Bishop of Caesarea, Julian the Apostate was the Roman Emperor and he ordered a heavy taxation on Caesarea for his war with Persia...The Emperor was killed at that war and the Bishop gathered all the money from the taxes and donated them to various charitable institutions...What was left from those coins, he ordered to be baked in bread and given to the poor...Thus, on the first of January,we have the custom of the Saint Basil's Bread.... grandmothers bake a bread in which they put a coin...whoever gets the fake gold coin gets a present...
