Father's Day is a day of honouring fatherhood and paternal bonds, as well as the influence of fathers in society. In Catholic countries of Europe, it has been celebrated on March 19 as Saint Joseph's Day since the Middle Ages. In America, Father's Day was founded by Sonora Smart Dodd, and celebrated on the third Sunday of June for the first time in 1910. The day is held on various dates across the world and different regions maintain their own traditions of honouring fatherhood. Father's day complements similar celebrations honouring family members, such as Mother's Day, Siblings Day and Grandparents' Day.
