Valentine's Day is indeed celebrated on the 14th of February and has become a significant cultural and commercial celebration of love and affection. The holiday has roots in both Christian and Roman traditions. While there are various legends associated with the origin of Valentine's Day, one of the popular ones involves a Christian martyr named St. Valentine.

According to one legend, St. Valentine was a Roman priest during the third century. The Roman Emperor Claudius II had prohibited young men from getting married, as he believed that single men made better soldiers. St. Valentine defied this decree and continued to perform marriages for young couples in secret. When his actions were discovered, he was arrested and later executed on February 14th.

Another legend suggests that St. Valentine, while imprisoned, fell in love with his jailor's daughter. Before his execution, he is said to have sent her a letter signed "from your Valentine," a phrase that has endured and is still used in modern Valentine's Day greetings.

Over time, Valentine's Day has evolved into a celebration of love and affection, marked by the exchange of cards, flowers, and gifts between romantic partners. It is celebrated in various countries around the world, and its traditions have expanded to include expressions of love for family and friends.
