Valentine's Day, celebrated on February 14th, is a holiday dedicated to love and affection between intimate partners. Its origins trace back to the Roman festival of Lupercalia, which was a celebration of fertility, but it later became associated with Saint Valentine, a Christian martyr. The day became more romantically linked during the Middle Ages when the tradition of courtly love flourished. People commonly express their love by exchanging cards, known as "valentines," flowers, chocolates, and other gifts. Romantic dinners and outings are popular activities that couples enjoy on this day. In recent times, Valentine's Day has expanded to include expressions of love between friends and family as well, not just romantic partners. The holiday is now celebrated worldwide, each culture adding its unique customs and traditions.
