Valentine’s Day, also called Valentine’s Day, is celebrated annually on February 14.

The day is celebrated by many countries around the world, although it is not a public holiday.

It began as a Christian holiday in honor of one or two early Christian martyrs named Saint Valentine and, through newer folk traditions, has become an important cultural, religious and commercial celebration of romance and love in many regions of the world.

The day was associated with lovers’ day by Geoffrey Chaucer in the late Middle Ages, when the culture of chivalrous love flourished.

In the 18th century in England it evolved into an occasion where lovers expressed their love with flowers, gifts or greeting cards.

In Europe, Valentine keys were given to lovers “as a romantic symbol and invitation to unlock their hearts”, as well as to children to ward off Valentine’s disease.

In the 19th century handwritten cards were replaced by mass-produced greeting cards.
