History of Saint Patrick's Day in the United States Part 2
The New York parade is moved to the previous Saturday (March 16) in years where March 17 is a Sunday. The event is also moved on the rare occasions when, due to Easter falling on a very early date, March 17 would land in Holy Week. This last occurred in 1913. That year the parade was held on Saturday, March 15, because Easter was on March 23 (making March 17 the Monday of Holy Week). This same scenario is scheduled to arise again in 2008, when Easter will also fall on March 23. In many other American cities (such as San Francisco), the parade is always held on the Sunday before March 17, regardless of the liturgical calendar.
Some cities paint the traffic stripe of their parade routes green. Others, including Chicago, dye major rivers green. Savannah also dyes its downtown city fountains green.
The longest-running Saint Patrick's Day celebrations in the U.S. are:
Although the baseball season usually is still in the spring training phase when St. Patrick's day rolls around, some teams such as the Chicago White Sox and Boston Red Sox, wear green uniforms for the occasion.
