According to Sunshineweek.org, “Sunshine Sunday began in Florida in 2002, led by the Florida Society of Newspaper Editors. National Sunshine Week was launched in 2005 by the American Society of Newspaper Editors with the support of the John S. and James L. Knight Foundation. In 2019, the American Society of News Editors merged with the Associated Press Media Editors to become the News Leaders Association.”

From The American Presidency Project, Proclamation 5447—Freedom of Information Day, 1986, “March 16 is the anniversary of the birth of James Madison, our fourth President and one of the principal figures in the Constitutional Convention. Madison eloquently expressed the guarantees in the Bill of Rights, in particular in the freedoms of religion, speech, and of the press protected by the First Amendment. He understood the value of information in a democratic society, as well as the importance of its free and open dissemination. He believed that through the interaction of the Government and its citizens, facilitated by a free press and open access to information, the Government could be most responsive to the people it serves. Surely the American experience has proved him right.

“This year [1986] marks the twentieth anniversary of the enactment by the Federal government of the Freedom of Information Act [1966]. On President Madison's birthday, it is particularly fitting that we recognize the value of reasonable access to information in our political process.” - Ronald Reagan, President of the United States of America
