La Chandeleur or now know in other parts in the world as national crêpe day. The Catholic holiday of Candlemas, celebrated every year on February 2, is a feast of crêpes that's meant to commemorate Mary and the presentation of baby Jesus 40 days from his birth. In France, this holiday is called la Chandeleur. They celebrate this holiday by holding a feast of crêpes. Jour des crêpes!
Not only do the french eat a lot of crêpes on la Chandeleur, but they also do a bit of fortune-telling while they make them. It is traditional to hold a coin in your writing hand and the crêpe pan in your other hand. Then flip the crêpe in the air. If you manage to catch the crêpe in the pan, your family will be supposedly prosperous.
