It is the traditional day on which lovers express their love for each other; sending Valentine's cards, donating to charity or gifting candy. It is very common to present flowers on Valentine's Day.
A continued point of controversy is whether courtly love was purely literary or was actually practiced in real life. There are no historical records that offer evidence of its presence in reality. Historian John Benton found no documentary evidence in law codes, court cases, chronicles or other historical documents. However, the existence of the non-fiction genre of courtesy books is perhaps evidence for its practice. For example, according to the courtesy book by Christine de Pizan called Book of the Three Virtues (ca. 1405), which expresses disapproval of courtly love, the convention was being used to justify and cover-up illicit love affairs. Courtly love probably found expression in the real world in customs such as the crowning of Queens of Love and Beauty at tournaments. Philip le Bon, in his Feast of the Pheasant in 1454, relied on parables drawn from courtly love to incite his nobles to swear to participate in an anticipated crusade, while well into the 15th century numerous actual political and
social conventions were largely based on the formulas dictated by the "rules" of courtly love.
