Bulgarians celebrate Baba Marta on March 1st by exchanging and wearing small dolls or tassels called "martenitsa" that are white and red in color. The martenitsa symbolizes new life, fertility, and spring. People wear the martenitsa until they see a stork, considered a sign of spring, or a blooming tree, at which point they remove it, believing winter is over. The tradition is a way to ask Baba Marta, a personification of March, for mercy and a swift end to winter.
