On March 28, 2017,  The Vietnam War Veterans Recognition Act of 2017, was signed into law, designating every March 29 as National Vietnam War Veterans Day.

National Vietnam War Veterans Day joins six other military-centric national observances codified in Title 4 of the United States Code §6 (i.e., Armed Forces Day, Memorial Day, Independence Day, National Korean War Veterans Armistice Day, Navy Day, Veterans Day).

March 29 was chosen to be celebrated in perpetuity as March 29, 1973 was the day Military Assistance Command Vietnam was deactivated.
