The Persian festival Yalda, or Shab-e Yalda is a celebration of the winter solstice in Iran that started in ancient times. It marks the last day of the Persian month of Azar. Yalda is viewed traditionally as the victory of light over dark, and the birthday of the sun god Mithra. Families celebrate together with special foods like nuts and pomegranates and some stay awake all night long to welcome the morning sun.
