New York City

New York hosts the country’s (and the world's) largestSt. Patrick’s Day celebration, with more than two million people gathering for the city’s grand parade on March 17. The march up Fifth Avenue starts at 11 am on 44th Street and lasts about six hours, ending at 79th, with a stop at the St. Patrick’s Cathedral along the way. There are no floats or cars allowed in the parade, which features bands, bagpipes, and dancers, and typically between 150,000 to 250,000 participants. The tradition itself dates back to 1762, making the NYC St. Patrick’s Day Parade older than the U.S. itself.

The city of Chicago truly commits toSt. Patrick’s Dayby dyeing the Chicago River green every season. The tradition dates back to 1961, when the chairman of the annual parade saw green dye in the river (which at the time was used to identify a sewage problem) and got the idea to use it for the upcoming holiday. On the Saturday before St. Patrick’s Day, more than 400,000 people gather along the Chicago River to watch 45 pounds of environmentally-safe vegetable dye turn the murky river a bright shade of green. After the morning's dyeing ceremony, even more spectators gather for the city’s parade at noon. The parade lasts about three hours, with dancers and bands making their way up Columbus Drive through Grant Park.
