I miss it EVERY year

When I was a child we weren't a very religious family, but every year we'd celebrate St. Nicholas Day. I think my mom and dad probably introduced it to us one year and every year after that we insisted on celebrating it. Until we were like 10 or something. I never knew why .. but I'd put my shoes outside the door, be it our bedroom door or the garage door, and the next day there would be candy in them. This is generally celebrated December 6th so I missed it again this year, but that got me thinking ... what is St. Nicholas day.
Here is an explanation via the wonderful world wide web:

Early in the Advent season celebrate a feast that has been popular for centuries in Christian countries, especially in Northern Europe. In our over-commercialized society, this holiday gives us a good "teaching moment" to remind children that Jolly Santa Claus, is, in fact, Saint Nicholas, a fourth century bishop of the city of Myra in what is now Turkey.

Saint Nicholas was renowned for his great kindness and his generous aid to those in distress. Among the kind and miraculous acts attributed to him are saving three young girls from prostitution by secretly providing them with dowries, raising three murdered boys from the dead, and saving sailors caught in stormy seas. For these reasons, he is considered the patron saint of children, unmarried girls, and sailors, among others.

Traditional celebrations of Saint Nicholas Day in Northern Europe included gifts left in children's shoes (the origin of our American Christmas stockings). Good children receive treats - candies, cookies, apples and nuts, while naughty children receive switches or lumps of coal. Sometimes coins were left in the shoes, reminiscent of the the life-saving doweries the saint provided. Today - especially in families of German extraction - children still put a shoe outside their bedroom doors on the eve of Saint Nicholas Day, and expect to find candy and coins or small gifts in their shoe on December 6th.

In some households the father of the family may dress up as Saint Nicholas on the eve of his feast. He comes in, sometimes with his sidekick, Krampus or Black Peter, and helps each child examine his conscience. He admonishes the bad and rewards the good. If your family enjoys theatrics, this is a wonderful opportunity early in Advent to inspire children to amend their ways in preparation for the coming King. (Your family might get together with other families with young children and celebrate together.)
