International Father’s Day is celebrated on the third Sunday of June every year. It is a day to honor fathers and father figures for their contributions to their families and communities.

The first Father’s Day was celebrated in Spokane, Washington, in 1910. Sonora Smart Dodd, who was raised by her father after her mother died, wanted to create a day to honor fathers. She chose the third Sunday of June because it was her father’s birthday.

Father’s Day is now celebrated in many countries around the world. It is a time for families to come together and celebrate the fathers in their lives.
