    On February 14, the western world celebrates Valentine’s Day. Valentine’s Day (named after an obscure Christian saint) was first associated with romantic love by English poet Geoffrey Chaucer in 1382.
    The tradition of expressing love on Valentine’s Day began in European courts in the Middle Ages, and thrived with the development of paper Valentine’s Day cards in the 19th century. Today, the Greeting Card Association sells more than 145 million Valentine’s Day cards every year. 
    Although Valentine’s Day is primarily a Western European holiday, businesses have established the tradition of sending cards, flowers, and other gifts throughout Latin America and eastern Asia as well. The holiday’s association with Christianity and its outward expression of affection make Valentine’s Day a contentious holiday in Islamic countries such as Saudi Arabia and Iran, however.
