NEW YORK - The Irish, their descendants and the Irish for the day are preparing to don green and pay tribute to Hibernian heritage.
A weekend of St. Patrick's Day celebrations is set from New York's Fifth Avenue to the Louisiana bayou to Dublin's Parnell Square.
With the holiday itself falling on a Sunday, many events are scheduled instead for Saturday because of religious observances.
New York's St. Patrick's Day Parade is due to proceed Saturday, with Irish Prime Minister Enda Kenny among the marchers.
Chicago is preparing for its own big parade and an eye-catching local custom: dying the Chicago River green.
Dublin's five-day St. Patrick's Day festival is unfolding with a new addition. For the first time, up to 8,000 visitors are expected to march in a "People's Parade" on Sunday.
