Saint Valentine's Day or Valentine's Day falls on February 14. It is the traditional day on which lovers express their love for each other; sending Valentine's cards, candy, or donations to charities, often anonymously. It is very common to present flowers on Valentine's Day.
The day is most closely associated with the mutual exchange  of love notes in the form of "valentines". Modern Valentine symbols  include the heart-shaped outline and the figure of the winged Cupid
The holiday is named after two men, both Christian martyrs named Valentine. The day became associated with romantic love in the High Middle Ages, when the tradition of courtly love flourished.

Valentine's Day combines ancient pagan rituals and Christian beliefs into one day. Although it is more commercialized  today with an emphasis on exchanging or receiving gifts, it still remains a day for lovers and friends. It is a day when we want to spend time with our mates and friends, but also lets take time to remember the love
that Saint Valentine; Patron of Valentine's Day had for our Lord Jesus Christ.

Stephan A.

Valentine's Day was probably imported into North America in the 19th century by British settlers. In the second half of the 20th century,  the practice of exchanging cards was extended to all manners of gifts
