Bulgarians celebrate Baba Marta in March (Grandma March). Giving each other martenitsas, which are little red and white weaved tassels, is a traditional way to celebrate this event. Wearing a martenitsa is customary up until you spot a stork or a swallow, which are regarded as signals of spring. A martenitsa on your wrist is said to bring luck and good health for the coming year.
