valentine is a card or gift given on Valentine’s Day. 

Valentine’s Day,[1] is celebrated annually on February 14.[2] It originated as a Christian feast day honoring one or two early Christian martyrs named Saint Valentine and, through later folk traditions, has become a significant cultural, religious, and commercial celebration of romance and love in many regions of the world.[3]

There are a number of martyrdom stories associated with various Valentines connected to February 14,[4] including an account of the imprisonment of the Saint of Rome for ministering to Christians persecuted under the Roman Empire in the third century.[5]

[6] According to an early tradition, the Saint restored sight to the blind daughter of his jailer.[7] Numerous later additions to the legend have better related it to the theme of love: an 18th-century embellishment to the legend claims he wrote the jailer’s daughter a letter signed

was established by Pope Gelasius I in AD 496 to be celebrated on February 14 in honour of Saint Valentine of Rome, who died on that date in AD 269.[9][10] The day became associated with romantic love in the 14th and 15th centuries when notions of courtly love flourished, apparently by association with the “lovebirds” of early spring. In 18th-century England, it grew into an occasion in which couples expressed their love for each other by presenting flowers, offering confectionery, and sending greeting cards .

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.[11] In Italy, Saint’s Keys are given to lovers “as a romantic symbol and an invitation to unlock the giver’s heart”, as well as to children to ward off epilepsy .[12]

this Day is not a public holiday in any country, although it is an official feast day in the Anglican Communion[13] and the Lutheran Church.[14] Many parts of the Eastern Orthodox Church also celebrate the Saint Day on July 6 in honor of Roman presbyter Saint Valentine, and on July 30 in honor of Hieromartyr , the Bishop of Interamna (modern Terni).[15]
