Now...some facts about this day

Saint Valentine's Day, often simply Valentine's Day, is observed on February 14 each year. Today Valentine's Day is celebrated in many countries around the world, mostly in the West, although it remains a working day in all of them.

The original "St. Valentine" was a liturgical celebration of one or more early Christian saints named Valentinus. Modern romantic connotations were added several centuries later by poets. Several martyrdom stories were invented for the various Valentines that belonged to February 14, and added to later martyrologies. This celebration was deleted from the General Roman Calendar of saints in 1969 by Pope Paul VI.

The day first became associated with romantic love in the circle of Geoffrey Chaucer in the High Middle Ages, when the tradition of courtly love flourished. By the 15th century, it had 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").

Modern Valentine's Day symbols 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.

In Brazil, the Dia dos Namorados (lit. "Lovers' Day", or "Boyfriends'/Girlfriends' Day") is celebrated on June 12, probably because it is the day before Saint Anthony's day, known there as the marriage saint, when traditionally many single women perform popular rituals, called simpatias, in order to find a good husband or boyfriend. Couples exchange gifts, chocolates, cards and flower bouquets. The February 14's Valentine's Day is not celebrated at all because it usually falls too little before or after the Brazilian Carnival— that can fall anywhere from early February to early March and lasts almost a week.
