Since 1972 Father’s Day has been highlighted by the president at the request of Congress. From 1972 through 1998 the request was made by a joint resolution. In 1998 the request was stuck into the United States Code.
36 USC 109 says
The third Sunday in June is Father’s Day.
(b)Proclamation.—The President is requested to issue a proclamation—
(1) calling on United States Government officials to display the flag of the United States on all Government buildings on Father’s Day;
(2) inviting State and local governments and the people of the United States to observe Father’s Day with appropriate ceremonies; and
(3) urging the people of the United States to offer public and private expressions of Father’s Day to the abiding love and gratitude they have for their fathers.”
Prior to the federal government stepping in, there was no Father’s Day. Just kidding.
At a YMCA in Spokane, Washington, on June 19, 1910, Sonora Smart Dodd gave a speech requesting that the ministers in the city give a sermon honoring fathers. Within a few decades June Father’s Day celebrations were common nationwide. Despite attempts right away and in the intervening decades, there was resistance at the federal level to making it an official holiday and it did not become an official holiday until 1972. This delay is in stark contrast to Mother’s Day which received Congressional recognition in 1914.
Happy Father’s Day!
