While most give a card and chocolates, it was customary for women in 18th-century Britain to pin bay leaves to the corners of their pillows. It was also tradition to eat eggs with salt replacing the yolks, which was said to encourage women to dream of their future husbands. Women would also write their lover's names on paper and place them in clay balls, which would be dropped into rivers or streams. Whichever paper came up first would be the first husband.
In Finland, Valentine's Day is called Ystävänpäivä, which translates as "Friend's Day". Rather than romance, it is a day when close friends send cards and gifts to each other. However, it is still a popular day for people to become engaged.

Spoons on Welsh Valentine's Day
This day actually takes place on 25 January and commemorates the Welsh saint Dwynwen. The legend states that she fell in love with a young price named Maeron, but they could not be together so an unknown reason. Three reasons are suggested: Maeron raped Dwynwen, her father forbade the marriage or her father had promised her to someone else.

Traditionally, St. Dwynwen's Day is celebrated by giving and receiving lovespoons.
In Japan, it is traditional for women to gift men chocolates, depending on the nature of their relationship. Giri-choko is bought for colleagues, bosses and close male friends.

Men are expected to return the favour one month later, with gifts at least two or three times as valuable than the chocolates they received. Not returning a gift is peceived as the man placing himself in a position of authority.
