Question: Lutzelfrau is a witch who gives gifts to children on a holiday on what date?
Context: Autumnal Equinox Day (秋分の日 , Shūbun no Hi ) is a public holiday in Japan that usually occurs on September 22 or 23, the date of Southward equinox in Japan Standard Time (autumnal equinox can occur on different dates for different timezones).  Due to the necessity of recent astronomical measurements, the date of the holiday is not officially declared until February of the previous year.  Autumnal Equinox Day became a public holiday in 1948.  In 1947 and before, it was the date of Shūki kōreisai (秋季皇霊祭 ) , an event relating to Shintoism.  Like other holidays, this holiday was repackaged as a non-religious holiday for the sake of separation of religion and state in Japan's postwar constitution. Saint Lucy's Day, also called the Feast of Saint Lucy, is a Christian feast day celebrated on 13 December in Advent, commemorating Saint Lucy, a 3rd-century martyr under the Diocletianic Persecution, who according to legend brought "food and aid to Christians hiding in the catacombs" using a candle-lit wreath to "light her way and leave her hands free to carry as much food as possible".  Her feast once coincided with the Winter Solstice, the shortest day of the year before calendar reforms, so her feast day has become a Christian festival of light.  Falling within the Advent season, Saint Lucy's Day is viewed as an event signaling the arrival of Christmastide, pointing to the arrival of the Light of Christ in the calendar, on Christmas Day. Lutzelfrau is a witch in German folklore who gives gifts — particularly apples, nuts and dried plums — to children on Saint Lucy's Day (December 13).  "Lutzelfrau" customs are also common in Slovenia and Croatia, where a "dark Luz" was contrasted to the Christian saint. Son of a Witch (2005, ISBN  ) is a fantasy novel written by Gregory Maguire.  The book is Maguire’s fifth revisionist story and the second set in the land of Oz originally conceived by L. Frank Baum.  It is a sequel to "" (1995).  Like "Wicked", "Son of a Witch" differs from the original series in tone: while Baum's books were intended as children's literature, "Son of a Witch" elaborates a darker and more mature side of the lighthearted world of Oz.  In an interview that is included with the "Son of a Witch" audio CD, Gregory Maguire gave two reasons for writing the book: "the many letters from young fans asking what happened to Nor, last seen as a chained political prisoner, and seeing the Abu Ghraib torture photographs."  "Son of a Witch" continues the story after the fall from power of the Wizard of Oz and the death of Elphaba, Maguire's reinvention of the Wicked Witch of the West.  As its title implies, the story elaborates the life of Elphaba’s possible son, Liir. The Père Fouettard (] ) (French for "Father Whipper") is a character who accompanies St. Nicholas in his rounds during St. Nicholas' Day (6 December) dispensing lumps of coal and/or floggings to the naughty children while St. Nick gives gifts to the well behaved.  He is known mainly in the far north and eastern regions of France and in the south of Belgium, although similar characters exist all over Europe (see Companions of Saint Nicholas).  This "Whipping Father" was said to bring a whip with him to spank all of the naughty kids who misbehaved. Dayenu (Hebrew:) is a song that is part of the Jewish holiday of Passover.  The word "Dayenu" means approximately "it would have been enough", "it would have been sufficient", or "it would have sufficed" ("day" in Hebrew is "enough", and "-enu" the first person plural suffix, "to us").  This traditional up-beat Passover song is over one thousand years old.  The earliest full text of the song occurs in the first medieval haggadah, which is part of the ninth-century Seder Rav Amram.  The song is about being grateful to God for all of the gifts he gave the Jewish people, such as taking them out of slavery, giving them the Torah and Shabbat, and had God only given one of the gifts, it would have still been enough.  This is to show much greater appreciation for all of them as a whole.  The song appears in the haggadah after the telling of the story of the exodus and just before the explanation of Passover, matzah and the maror. While many people believe that the act of giving gifts during Christmas became a tradition due to the biblical story about how the three wise men brought gifts of gold, myrrh, and frankincense to the baby Jesus, these gifts were not the first winter gifts given.  In fact, gift giving during the winter is an ancient tradition that can even be traced to winter-solstice celebrations before the famous birth occurred.  During the ancient ceremonies of Saturnalia, which were celebrated for seven days beginning on December 17, Romans believed that their generosity of trading gifts would bring them good fortune in the coming year.  In the beginning, these gifts were very modest and included things like wax candles, fruits and nuts, inexpensive wine, and lamps that were tied with a bit of holly to signify the return of light that would come with the passing of the winter equinox.  Children would receive small items like terra-cotta rings and tiny dolls made from dough.  Later, however, the gifts became more elaborate items like silver and silver objects. Saint Nicholas' Day, observed on December 6 in Western Christian countries, December 5 in the Netherlands and December 19 in Eastern Christian countries, is the feast day of Saint Nicholas.  It is celebrated as a Christian festival with particular regard to his reputation as a bringer of gifts, as well as through the attendance of Mass or worship services.  In Europe, especially in "Germany and Poland, boys would dress as bishops begging alms for the poor."  In Ukraine, children wait for St. Nicholas to come and to put a present under their pillows provided that the children were good during the year.  Children who behaved badly may expect to find a twig or a piece of coal under their pillows.  In the Netherlands, "Dutch children put out a clog filled with hay and a carrot for Saint Nicholas' horse.  On Saint Nicholas' Day, gifts are tagged with personal humorous rhymes written by the sender."  In the United States, one custom associated with Saint Nicholas Day is children leaving their shoes in the foyer on Saint Nicholas Eve in hope that Saint Nicholas will place some coins on the soles, for them to awake to. White Sunday is a national holiday in Samoa falling on the second Sunday of October, with the Monday following a public holiday.  It is a day for parents and communities to acknowledge and celebrate childhood by hosting special programs during church services which include scriptural recitations.  Biblical story reenactments, and creative dance performances.  Children receive gifts (often new clothing and/or school supplies) on White Sunday and are allowed privileges normally reserved for elders, such as being the first to be served food at family meal time. Ghede Linto is a loa that performs miracles, although many think he's a small boy because of his politeness.  About 5 feet tall, Linto is an old, dark-skinned man with a cane, glasses, and an old-fashioned black hat.  He's very well mannered and docile.  He loves to teach his worshipers to sing, and enjoys leaving them gifts he makes out of rum, Florida Water, a cigarette and fire.  He cuts a piece of thread for each of his servants, or children from his house, and drops the threads in his special mix to produce needles for everyone; other times, gifts like gold rings or gold chains are given.  He loves to make knots out of their scarves just to surprise them with gifts.  Linto does these miracles to ensure his children they are in good hands.
