Saint Valentine's Day or Valentine's Day is a saints day commemorating Saint Valentine on February 14. It is the traditional day on which lovers express their love for each other; sending Valentine's cards, donating to charity or gifting candy. It is very common to present flowers on Valentine's Day. The holiday is named after two men, both Christian martyrs among the numerous Early Christian martyrs named Valentine. The day became associated with romantic love in the circle of Geoffrey Chaucer in High Middle Ages, when the tradition of courtly love flourished.
Though popular modern sources link unspecified Graeco-Roman February holidays alleged to be devoted to fertility and love to St Valentine's Day, Jack Oruch has demonstrated[4] that prior to Chaucer, no links between the Saints named Valentinus and romantic love existed. Thus whether or not in the ancient Athenian calendar, the period between mid-January and mid-February was the month of Gamelion, was dedicated to the sacred marriage of Zeus and Hera is immaterial.
Valentine's Day also has regional traditions in the UK. In Norfolk a character called 'Jack' Valentine knocks on the rear door of houses leaving sweets and presents for children. Although he was leaving treats, many children were scared of this mystical person.
