Father's Day
Father's Day was not celebrated in the US, outside Catholic traditions, until the 20th century. As a civic celebration in the US, it was inaugurated in the early 20th century to complement Mother's Day by celebrating fathers and male parenting.
After Anna Jarvis' successful promotion of Mother's Day in Grafton, West Virginia, the first observance of a "Father's Day" was held on July 5, 1908, in Fairmont, West Virginia, in the Williams Memorial Methodist Episcopal Church South, now known as Central United Methodist Church. Grace Golden Clayton was mourning the loss of her father, when in December 1907, the Monongah Mining Disaster in nearby Monongah killed 361 men, 250 of them fathers, leaving around a thousand fatherless children. Clayton suggested that her pastor Robert Thomas Webb honor all those fathers.
Saint Patrick's Day in the United States
The New York parade is moved to the previous Saturday (16 March) in years where 17 March is a Sunday. The event also has been moved on the rare occasions when, due to Easter's falling on a very early date, 17 March would land in Holy Week. This same scenario arose again in 2008, when Easter fell on 23 March, but the festivities occurred on their normal date and were enjoyed by a record number of viewers. In many other American cities (such as Philadelphia), the parade is always held on the Sunday before 17 March, regardless of the liturgical calendar.
