The document summarizes the Bulgarian tradition of Baba Marta's Day and martenitsas celebrated on March 1st. The tradition originated from a story where a swallow delivered a message to the Bulgarian people with a white string tied to its leg that had been bloodied, symbolizing new life. Now on March 1st, Bulgarians make and give martenitsas, which are red and white strings representing life and hope, to family and friends. People wear them until the first signs of spring and believe martenitsas bring health, happiness and luck for the new year. The tradition helps mark the end of winter and beginning of spring.
