On June 19, 1910, the governor of the U.S. state of Washington proclaimed the nationâs first âFatherâs Day.â However, it was not until 1972, 58 years after President Woodrow Wilson made Motherâs Day official, that the day became a nationwide holiday in the United States.
Six years later, the day was made a permanent national holiday when President Richard Nixon signed it into law in 1972. In addition to Father's Day, International Men's Day is celebrated in many countries on November 19 for men and boys who are not fathers.
