Santa's List Day

04 Dec
Santa's List Day has found two potential meanings for this holiday: either this is the day that Santa makes his Naughty and Nice lists, or that this is the day that kids need to mail their lists of things they want to Santa so that his elves have enough time to make all the Christmas presents.
There are more references to the Naughty/Nice list meaning for this holiday, though none of them are authoritative and we wonder if these lists are finalized closer to Christmas to make sure kids are still being good during the holiday season. Otherwise, that could potentially give the kids 17 days of bad behavior immunity.
Perhaps, this holiday was meant to remind kids that Santa will be finalizing his lists -- Naughty, Nice, Gifts -- in the near future.
To be on the safe side until we know more about this holiday's origin, this is a good day for the kids to send their Christmas lists to give Santa and his elves enough time, and that they should be extra good now and leading up to Christmas to make sure they end up on the right list.

Santa Claus

Santa Claus, also known as Saint Nicholas, Father Christmas and simply 'Santa', is a figure with legendary, mythical, historical and folkloric origins who, in many western cultures, is said to bring gifts to the homes of the good children during the late evening and overnight hours of Christmas Eve, December 24. The modern figure was derived from the Dutch figure of Sinterklaas,which, in turn, may have part of its basis in hagiographical tales concerning the historical figure of gift giver Saint Nicholas. A nearly identical story is attributed by Greek and Byzantine folklore to Basil of Caesarea. Basil's feast day on January 1 is considered the time of exchanging gifts in Greece.
Santa Claus is generally depicted as a portly, joyous, white-bearded man - sometimes with spectacles - wearing a red coat with white collar and cuffs, white-cuffed red trousers, and black leather belt and boots (images of him rarely have a beard with no moustache). This image became popular in the United States and Canada in the 19th century due to the significant influence of Clement Clarke Moore's 1823 poem 'A Visit From St. Nicholas' and of caricaturist and political cartoonist Thomas Nast. This image has been maintained and reinforced through song, radio, television, children's books and films.
According to a tradition which can be traced to the 1820s, Santa Claus lives at the North Pole, with a large number of magical elves, and nine (originally eight) flying reindeer. Since the 20th century, in an idea popularized by the 1934 song 'Santa Claus Is Coming to Town', Santa Claus has been believed to make a list of children throughout the world, categorizing them according to their behavior ('naughty' or 'nice') and to deliver presents, including toys, and candy to all of the well-behaved children in the world, and sometimes coal to the naughty children, on the single night of Christmas Eve. He accomplishes this feat with the aid of the elves who make the toys in the workshop and the reindeer who pull his sleigh.

Saint Nicholas

Saint Nicholas of Myra is the primary inspiration for the Christian figure of Sinterklaas. He was a 4th century Greek Christian bishop of Myra (now Demre) in Lycia, a province of the Byzantine Anatolia, now in Turkey. Nicholas was famous for his generous gifts to the poor, in particular presenting the three impoverished daughters of a pious Christian with dowries so that they would not have to become prostitutes. He was very religious from an early age and devoted his life entirely to Christianity. In continental Europe (more precisely the Netherlands, Belgium, Austria and Germany) he is usually portrayed as a bearded bishop in canonical robes. In 1087, the Italian city of Bari, wanting to enter the profitable pilgrimage industry of the times, mounted an expedition to locate the tomb of the Christian Saint and procure his remains. The reliquary of St. Nicholas was desecrated by Italian sailors and the spoils, including his relics, taken to Bariwhere they are kept to this day. A basilica was constructed the same year to store the loot and the area became a pilgrimage site for the devout, thus justifying the economic cost of the expedition. Saint Nicholas was later claimed as a patron saint of many diverse groups, from archers, sailors, and children to pawnbrokers. He is also the patron saint of both Amsterdam and Moscow.
