Valentine's Day is a holiday celebrated on February 14 by many people throughout the world. In the English-speaking countries, it is the traditional day on which lovers express their love for each other by sending Valentine's cards, presenting flowers, or offering confectionery. The holiday is named after two among the numerous Early Christian martyrs named Valentine. The day became associated with romantic love in the circle of Geoffrey Chaucer in the High Middle Ages, when the tradition of courtly love flourished.
In the second half of the twentieth century, the practice of exchanging cards was extended to all manner of gifts in the United States, usually from a man to a woman. 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 day has come to be associated with a generic platonic greeting of "Happy Valentine's Day." As a joke, Valentine's Day is also referred to as "Singles Awareness Day." In some North American elementary schools, children decorate classrooms, exchange cards, and eat sweets. The greeting cards of these students often mention what they appreciate about each other.
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.
The U.S. Greeting Card Association estimates that approximately one billion valentines are sent each year worldwide, making the day the second largest card-sending holiday of the year, behind Christmas. The association estimates that, in the US, men spend on average twice as much money as women. (From: Wikipedia, license: CCA-SA)
