Chestita Baba Marta!

In Bulgaria, on the first of March it is customary to exchange small red and white bracelets or talismans called martenitsi (which can be purchased for next to nothing on any street corner) and greet everyone with “Честита Баба Марта!” (literally translated: "Happy Grandmother March!") So far, I've received 3 and given away 5—it’s just like Valentine's Day in elementary school. You are then supposed to wear at least one bracelet until the first day of spring, or until you see the first stork, at which time you then tie the bracelet to a tree branch.
