November 11 is celebrated as the Feast of Saint Martin of Tours, one of the most beloved saints in Western Christianity. In Belgium, this day is also linked to local autumn festivals and acts of charity.
- Martin – From the Latin Martinus, derived from Mars, the Roman god of war, meaning warlike. It honors Saint Martin of Tours, a Roman soldier turned monk, remembered for his compassion—especially the story of sharing his cloak with a beggar.
- Maarten – The Dutch and Flemish form of Martin, sharing the same origin and meaning. It is particularly common in Flanders, where Sint-Maarten festivities include lantern processions and giving treats to children.
