Congress passed a joint resolution on 30 April 1934 (Pub. Res. 73-21, 48 Stat. 657) asking the President to proclaim 12 October each year as Columbus Day and to have the flag flown on government buildings, and Franklin D. Roosevelt did so in Proclamation 2101 on 30 September 1934. Neither instrument made it a holiday: the Uniform Monday Holiday Act (Pub. L. 90-363, 28 June 1968, 82 Stat. 250) added Columbus Day to the federal legal public holidays in 5 U.S.C. 6103(a) and set it on the second Monday in October, effective 1 January 1971.
A proclamation that explains itself
Harrison's Columbus proclamation sits between those two messages, signed on July 21, 1892. It recites only two grounds: a joint resolution approved on June 29, 1892, and the four hundredth anniversary. The New Orleans case is not among its grounds.
