My favorite of these is this one from Bulgaria:
In Bulgaria, today is Baba Marta, or "Grandmother March Day." Baba Marta is a mythical figure, a temperamental old lady with big mood swings that correlate with the Bulgarian climate. When she's happy, she brings warm weather. When she's angry, the winter frost persists. So today, people in Bulgaria go around greeting each other "Chestita Baba Marta" — which means "Happy Grandmother March" — hoping that the old lady will be cheerful and bring warm weather and sunshine. And today in Bulgaria, people wear martenitsi. The martenitsa is a red and white brooch-like adornment made of yarn. It is supposed to make Baba Marta have mercy on the wearers and allow them be happy, so that they may all welcome the coming spring as soon as possible.I thought this was intriguing, so looked it up on the ever-informative Internet, and found this great site with lots more about Grandmother March and the martenitsi: history, traditions, and best of all - folk tales about the day.This is a day for cheerful optimism and hope, for getting rid of the winter doldrums, pleasing Grandmother March so that the birds will return, the fruit trees will blossom into life, the beasts bear their young. It's too late for this March 1st. not a scrap of yarn in the house - but by next March I'm going to have a little stash of martenitsi ready for greeting Baba Marta.
