Father’s Day is a day dedicated to fathers, celebrated on the third Sunday of June in many countries including the United States, Canada, and the United Kingdom. The day is a celebration of fatherhood and the influence of fathers in the lives of their children. Father’s Day was first celebrated in the early 20th century in the United States to complement Mother’s Day, which celebrates mothers around the world. Many people mark the day by giving gifts, spending time with their fathers, and expressing gratitude for their love and support.
