why valentine's day is celebrated ?

Valentine's Day is celebrated on February 14th and is a holiday that honors Saint Valentine, a Catholic priest who lived in the 3rd century. According to one popular legend, Saint Valentine performed secret marriages for Christian couples who were not allowed to wed because of a ban imposed by the Roman Empire. In another legend, Saint Valentine was imprisoned and ultimately executed for helping Christians escape Roman prisons. He became the patron saint of lovers and his name became associated with the celebration of love and affection that we now know as Valentine's Day.

Today, Valentine's Day is celebrated in many countries around the world as a day to express love and affection to significant others, friends, and family. People typically exchange cards, gifts, and flowers, and share special meals and treats to mark the occasion. The holiday has also become a commercialized occasion, with the sale of cards, chocolates, and other gifts contributing to the economy.
