Valentin’s reference is the Valentine Day Valentine's Day, also called Saint Valentine's Day or the Feast of Saint Valentine, is celebrated annually on February 14. 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. There are a number of martyrdom stories associated with various Valentines connected to February 14, including an account of the imprisonment of Saint Valentine of Rome for ministering to Christians persecuted under the Roman Empire in the third century. According to an early tradition, Saint Valentine restored sight to the blind daughter of his jailer. 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 "Your Valentine" as a farewell before his execution. Another tradition posits that Saint Valentine performed weddings for Christian soldiers who were forbidden to marry. There is a tradition that the Feast of Saint Valentine was established by Pope Gelasius I in AD 496 to be celebrated on February 14 in honor of Saint Valentine of Rome. The feast is found in the Gelasian Sacramentary (which was compiled after Gelasius), meaning that it has been observed since at least the eighth century. 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.
