Valentine's Day is celebrated on February 14th. It originated from both a Roman fertility festival called Lupercalia, where names were drawn to pair unmarried people, and from Saint Valentine, a priest who secretly married couples against the Roman emperor's orders and was imprisoned and killed on February 14th. Common Valentine's Day symbols include Cupid representing love and desire, and hearts representing passion which originated from an ancient contraceptive plant.
