Father's Day
Father's Day, is observed on the feast day of Fathers. It is celebrated as a public international day, like in many other countries including the U.S., on the third Sunday of June.
In Greece, like in other European countries, this day is named (Fête des Peres/Feast of 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.
