Celebrated on the third Sunday of June, Father’s Day is celebrated to recognise the contribution of fathers and fatherhood. Although different countries celebrate Father’s Day on different dates, the date of third Sunday as Father’s Day was first observed by USA and subsequently adopted my many countries.
In several countries of Europe, Father’s Day is celebrated on 19th March, as St. Joseph’s Day. In Germany, Father's Day is celebrated on the same date as Ascension Day. In USA, Mrs. Sonora Dodd is said to be the founder of Fathers’ Day, who requested that a day be commemorated in the memory of her father, a war veteran, as also all fathers around the world.
