Saint Patrick's Day first began in the 17th century as a religious feast in honor of Saint Patrick and his introduction of Christianity to Ireland. Today, it is the most widely celebrated national festival globally, particularly by North Americans of Irish descent. Celebrations include parades, music sessions, festivals, and, most commonly, "wearing of the green." In Ireland, the week of Saint Patrick's Day is known as "Irish Language Week," during which people will make an effort to use the Irish language.
