St. Patrick's Day is observed on March 17th because that is the feast of St. Patrick, the patron saint of Ireland. It is believed that he died on March 17th in the year 461 AD in the town of Saul and is burried at Downpatrick. It is also a worldwide celebration of Irish culture and history. St. Patrick's Day is a national holiday in Ireland, and a provincial holiday in the Canadian province of Newfoundland and Labrador.
In Ireland on St. Patrick's day, people traditionally wear a small bunch of shamrocks on their jackets or caps. Children wear orange, white and green badges and women and girls wear green ribbons in their hair.
34 million Americans have Irish ancestry, according to the 2003 US Census. That's almost nine times the population of Ireland, which has 4.1 million people. Some American towns have "Irish" names.
