What do we celebrate at valentine's day?

Saint Valentine's Day, commonly known as Valentine's Day, or the Feast of Saint Valentine, isobserved on February 14 each year. It is celebrated in many countries around the world, although it remains a working day in most of them.

St. Valentine's Day began as a liturgical celebration of one or more early Christian saints named Valentinus. The most popular martyrology associated with Saint Valentine was 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.
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. 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"). Since the 19th century, handwritten valentines have given way to mass-produced greeting cards.Valentine's Day symbols that are used today include the heart-shaped outline, doves, and the figure of the winged Cupid. In the second half of the 20th century, the practice of exchanging cards was extended to all manner of gifts. Such gifts typically include roses and chocolates packed in a red satin, heart-shaped box. In the 1980s, the diamond industry began to promote Valentine's Day as an occasion for giving jewelry.


The U.S. Greeting Card Association estimates that approximately 190 million valentines are sent each year in the US. Half of those valentines are given to family members other than husband or wife, usually to children. When you include the valentine-exchange cards made in school activities the figure goes up to 1 billion, and teachers become the people receiving the most valentines.
The rise of Internet popularity at the turn of the millennium is creating new traditions. Millions of people use, every year, digital means of creating and sending Valentine's Day greeting messages such as e-cards, love coupons or printable greeting cards. An estimated 15 million e-valentines were sent in 2010.
