Saint Martin's Day, also known as the Feast of Saint Martin, Martinstag or Martinmas, as well as Old Halloween and Old Hallowmas Eve, is the feast day of Saint Martin of Tours (Martin le Miséricordieux) and is celebrated on November 11 each year. This is the time when autumn wheat seeding was completed, and the annual slaughter of fattened cattle produced "Martinmas beef". Historically, hiring fairs were held where farm laborers would seek new posts.
Saint Martin of Tours started out as a Roman soldier then was baptized as an adult and became a monk. It is understood that he was a kind man who led a quiet and simple life. The best known legend of his life is that he once cut his cloak in half to share with a beggar during a snowstorm, to save the beggar from dying from the cold. That night he dreamed that Jesus was wearing the half-cloak. Martin heard Jesus say to the angels, "Here is Martin, the Roman soldier who is now baptised; he has clothed me."
St. Martin was known as friend of the children and patron of the poor. This holiday originated in France, then spread to the Low Countries, the British Isles, Germany, Scandinavia, and Eastern Europe. It celebrates the end of the agrarian year and the end of the harvest. Bishop Perpetuus of Tours, who died in 490, ordered fasting three days a week from the day after Saint Martin's Day (11 November). In the 6th century, local councils required fasting on all days except Saturdays and Sundays from Saint Martin's Day to Epiphany (the Feast of the Three Wise Men and the star, c.f. Matthew 2: 1-12) on January 6, a period of 56 days, but of 40 days fasting, like the fast of Lent. It was therefore called Quadragesima Sancti Martini (Saint Martin's Lent). This period of fasting was later shortened and called "Advent" by the Church.
The goose became a symbol of St. Martin of Tours because of a legend that when trying to avoid being ordained bishop he had hidden in a goose pen, where he was betrayed by the cackling of the geese. St. Martin's feast day falls in November, when geese are ready for killing. St. Martin’s Day was an important medieval autumn feast, and the custom of eating goose spread to Sweden from France. It was primarily observed by the craftsmen and noblemen of the towns. In the peasant community, not everyone could afford to eat goose, so many ate duck or hen instead.
