Saint Valentine's Day, also known as Valentine's Day or the Feast of Saint Valentine, is observed on February 14 each year. It is celebrated in many countries around the world, although it is not a holiday in most of them. St. Valentine's Day began as a liturgical celebration of one or more early Christian saints named Valentinus. Several martyrdom stories were invented for the various Valentines that belonged to February 14, and added to later martyrologies.
A popular hagiographical account of Saint Valentine of Rome states that he was imprisoned for performing weddings for soldiers who were forbidden to marry and for ministering to Christians, who were persecuted under the Roman Empire. According to legend, during his imprisonment, he healed the daughter of his jailer, Asterius. An embellishment to this story states that before his execution he wrote her a letter signed "Your Valentine" as a farewell. Today, Saint Valentine's Day is an official feast day in the Anglican Communion, as well as in the Lutheran Church.
The day was first associated with romantic love in the circle of Geoffrey Chaucer in the High Middle Ages, when the tradition of courtly love flourished. In 18th-century England, it evolved into an occasion in which lovers expressed their love for each other by presenting flowers, offering confectionery, and sending greeting cards (known as "valentines"). Valentine's Day symbols that are used today include the heart-shaped outline, doves, and the figure of the winged Cupid. Since the 19th century, handwritten valentines have given way to mass-produced greeting cards.
Numerous early Christian martyrs were named Valentine. The Valentines honored on February 14 are Valentine of Rome and Valentine of Terni. The Catholic Encyclopedia also speaks of a third saint named Valentine who was mentioned in early martyrologies under date of February 14. He was martyred in Africa with a number of companions, but nothing more is known about him.
While the European folk traditions connected with Saint Valentine and St. Valentine's Day have become marginalized by the modern Anglo-American customs connecting the day with romantic love, there are some remaining associations connecting the saint with the advent of spring. While the custom of sending cards, flowers, chocolates and other gifts originated in the UK, Valentine's Day still remains connected with various regional customs in England. In Norfolk, a character called 'Jack' Valentine knocks on the rear door of houses leaving sweets and presents for children.
In Slovenia, Saint Valentine or Zdravko was one of the saints of spring, the saint of good health and the patron of beekeepers and pilgrims. A proverb says that "Saint Valentine brings the keys of roots". Plants and flowers start to grow on this day. It has been celebrated as the day when the first work in the vineyards and in the fields commences. It is also said that birds propose to each other or marry on that day. Another proverb says "Valentin – prvi spomladin" ("Valentine — the first spring saint"), as in some places (especially White Carniola), Saint Valentine marks the beginning of spring. Valentine's Day has only recently been celebrated as the day of love.
In Ancient Rome, Lupercalia, observed February 13–15, was an archaic rite connected to fertility. Lupercalia was a festival local to the city of Rome. The more general Festival of Juno Februa, meaning "Juno the purifier "or "the chaste Juno", was celebrated on February 13–14. Pope Gelasius I (492–496) abolished Lupercalia. Some researchers have theorized that Gelasius I replaced Lupercalia with the celebration of the Purification of Mary in February 14 and claim a connection to the 14th century's connotations of romantic love, but there is no historical indication that he ever intended such a thing.
