Father's Day
Father's Day is a celebration honoring fathers and celebrating fatherhood, paternal bonds, and the influence of fathers in society. In Catholic Europe, it has been celebrated on March 19 (St. Joseph's Day) since the Middle Ages. This celebration was brought by the Spanish and Portuguese to Latin America, where March 19 is often still used for it, though many countries in Europe and the Americas have adopted the U.S. date, which is the third Sunday of June. It is celebrated on various days in many parts of the world, most commonly in the months of March, April and June. It complements similar celebrations honoring family members, such as Mother's Day, Siblings Day, and Grandparents' Day.
National Grandparents Day
The celebration was introduced to the UK in 1990 by the charity Age Concern. It has been celebrated on the first Sunday in October since 2008, although it is not widely advertised and has not been as commercially successful as Mother's and Father's Day. Businesses specialising in gifts and greeting cards have started merging the respective grandparents days with Mother's Day and Father's Day to try to boost sales.
