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
St. Patrick's Day is indirectly observed as an official holiday in Boston, as it coincides with the official Evacuation Day holiday observed annually since 1901 to commemorate the day in 1776 that British troops ended their occupation of Boston. A large St. Patrick's Day parade is held in South Boston, Massachusetts. The 3.2-mile parade route starts at Andrew Square (at Broadway MBTA Red Line stop), at the intersection of Dorchester Avenue and Broadway in South Boston, Massachusetts, and travels Dorchester Street to Telegraph Street looping through Dorchester Heights and then bearing right onto East Fourth Street it continues down to 'P' Street bearing left onto East Broadway where it ends (at the Andrew MBTA Red Line stop). Major George F.H. Murray of the Ninth Regiment of the Army was the first chief marshal of Boston's St Patrick's Day parade in 1901. In 2015 the first gay groups (Boston Pride and OutVets) marched in Boston's St. Patrick's Day parade.
