U.S. Flag protocol

The National Archives notes that U.S. flags nationwide are to be flown at half-staff for 30 days following a president's death, according to protocol set in 1954.

In that year, President Dwight Eisenhower signed a proclamation on rules with respect to the display of the nation’s flag at half-staff upon the death of the certain designated officials. For a president or former president, the flag is to be at half staff for 30 days from the day of death. This includes all buildings, grounds, and naval vessels of the Federal Government in the District of Columbia and throughout the U.S. and its Territories and possessions. The flag shall also be flown at half-staff for such period at all U.S. embassies, legations, and other facilities abroad, including all military facilities and naval vessels and stations.
