Valentine's Day is celebrated annually on February 14. It originated as a Christian feast day honouring one or perhaps two early Christian martyrs named Saint Valentine. Through later folk traditions, it has become a significant cultural, religious, and commercial celebration of romance and love in many regions of the world.
Valentine's Day customs – sending greeting cards (known as "valentines"), offering confectionery and presenting flowers – developed in early modern England and spread throughout the English-speaking world in the 19th century and then worldwide. (source - Wikipedia).
