Valentine's Day was once thought to be the day that birds found their mates.

In Great Britain women would write the name of their sweethearts on scraps of paper. The paper was then placed in clay balls and dropped into water. The name that floated to the top first was though to be the one they would marry.

In Wales wooden love spoons were given as gifts. It was popular to decorate them with hearts, keys, and keyholes. These carried the meaning of "You unlock my heart!"

In the 14 century sweethearts for the day were chosen by lot.

In Denmark it is customary to send white pressed flowers called snowdrops to friends.
