Croissant Day celebrates the delicious crescent-shaped pastry. Croissants are popular pastries in France and Austria, where they were invented. They were adapted from another crescent-shaped Austrian pastry called a Kipferl. It was the French imitators who named the pastry a croissant, the French word for crescent. There are many legends associated with the invention of the croissant, most of which have to do with celebrating the defeat of enemy forces. In one story it celebrates the French defeating the Umayyad forces who used the Islamic crescent moon as their symbol.In another story it celebrates the Austrians defeating the Ottomans, who had a crescent moon on their flag. Neither story can be proved, but they are both a testament to how ingrained croissants are in these two countries’ culture.
