The day became associated with romantic love in the 14th and 15th centuries when notions of courtly love flourished, apparently by association with the “lovebirds” of early spring. In 18th-century England, it grew into an occasion in which couples expressed their love for each other by presenting flowers, offering confectionery, and sending greeting cards (known as “valentines”). Valentine’s Day symbols that are used today include the heart-shaped outline, doves, and the figure of the winged Cupid.

In Italy, Saint Valentine’s Keys are given to lovers “as a romantic symbol and an invitation to unlock the giver’s heart”.

Saint Valentine’s Day is not a public holiday in any country, although it is an official feast day in the Anglican Communion[11] and the Lutheran Church.[12] Many parts of the Eastern Orthodox Church also celebrate Saint Valentine’s Day on July 6 in honour of Roman presbyter Saint Valentine, and on July 30 in honour of Hieromartyr Valentine, the Bishop of Interamna.
