Valentine's Day, celebrated on February 14, is a day dedicated to expressing love and affection. It is named after Saint Valentine, a Christian martyr known for his acts of love and compassion. People often exchange gifts, cards, and flowers to show their feelings for partners, friends, and family. The day has evolved into a commercial celebration, with many businesses promoting romantic dinners, chocolates, and greeting cards. While it is primarily associated with romantic love, Valentine's Day also encourages appreciation for friendships and familial bonds, making it a broader celebration of love in various forms.
